### Field Detail

#### NO_TYPE

    public static final SchemaType NO_TYPE

The SchemaType object given to an XmlObject instance when no type can be determined.

The NO_TYPE is the universal derived type. That is, it is derived from all other schema types, and no instances of the NO_TYPE are valid. (It is not to be confused with the anyType, which is the universal base type from which all other types can be derived, and of which all instances are valid.)

### Method Detail

    public static String compilePath(String pathExpr)
                              throws XmlException

Compiles an XPath, returning a String equal to that which was passed, but whose identity is that of one which has been precompiled and cached.

Throws:
  `XmlException`

#### compilePath

    public static String compilePath(String pathExpr,
                                     XmlOptions options)
                              throws XmlException

Compiles an XPath, returning a String equal to that which was passed, but whose identity is that of one which has been precompiled and cached; takes an option for specifying text that indicates the name of context node. The default is "this", as in "$this".

Parameters:
  `options` - Options for the path. For example, you can call the `XmlOptions.setXqueryCurrentNodeVar(String)` method to specify a particular name for the expression variable that indicates the context node.
Throws:
  `XmlException`

#### compileQuery

    public static String compileQuery(String queryExpr)
                               throws XmlException

                               throws XmlException

Compiles an XQuery, returning a String equal to that which was passed, but whose identity is that of one which has been precompiled and cached; takes an option for specifying text that indicates the context node.

Parameters:
  `options` - Options for the query.

Throws:
  `XmlException`

#### getContextTypeLoader

    public static SchemaTypeLoader getContextTypeLoader()

The "parse" methods of XmlBeans all delegate to the "parseInstance" methods of the context type loader.

#### getBuiltinTypeSystem

    public static SchemaTypeSystem getBuiltinTypeSystem()

Returns the builtin type system. This SchemaTypeSystem contains only the 46 builtin types defined by the XML Schema specification.

    public static SchemaTypeLoader loadXsd(XmlObject... schemas)
                                    throws XmlException

Returns the SchemaTypeSystem that results from compiling the XML schema definitions passed.

Just like compileXsd, but uses the context type loader for linking, and returns a unioned typeloader that is suitable for creating instances.

Throws:
  `XmlException`

#### loadXsd

    public static SchemaTypeLoader loadXsd(XmlObject[] schemas,
                                           XmlOptions options)
                                    throws XmlException

Returns the SchemaTypeSystem that results from compiling the XML schema definitions passed in schemas.

This is just like compileXsd, but uses the context type loader for linking, and returns a unioned typeloader that is suitable for creating instances.

Use the options parameter to specify one or both of the following:

- A collection instance that should be used as an error listener during compilation, as described in `XmlOptions.setErrorListener(java.util.Collection<org.apache.xmlbeans.XmlError>)`.
- Whether validation should not be done when building the SchemaTypeSystem, as described in `XmlOptions.setCompileNoValidation()`.

Parameters:
  `schemas` - The schema definitions from which to build the schema type system.
  `options` - Options specifying an error listener and/or validation behavior.
Throws:
  `XmlException`

#### compileXsd

    public static SchemaTypeSystem compileXsd(XmlObject[] schemas,
                                              SchemaTypeLoader typepath,
                                              XmlOptions options)
                                       throws XmlException

Returns the SchemaTypeSystem that results from compiling the XML schema definitions passed.

The XmlObjects passed in should be w3c <schema> elements whose type is org.w3c.x2001.xmlSchema.Schema. (That is, schema elements in the XML namespace http://www.w3c.org/2001/XMLSchema.) Also org.w3c.x2001.xmlSchema.SchemaDocument is permitted.

The optional second argument is a SchemaTypeLoader which will be consulted for already-compiled schema types which may be linked while processing the given schemas.

The SchemaTypeSystem that is returned should be combined (via `typeLoaderUnion(org.apache.xmlbeans.SchemaTypeLoader...)`) with the typepath typeloader in order to create a typeloader that can be used for creating and validating instances.

Use the options parameter to specify the following:

- A collection instance that should be used as an error listener during compilation, as described in `XmlOptions.setErrorListener(java.util.Collection<org.apache.xmlbeans.XmlError>)`.
- Whether validation should not be done when building the SchemaTypeSystem, as described in `XmlOptions.setCompileNoValidation()`.

Parameters:
  `schemas` - The schema definitions from which to build the schema type system.
  `typepath` - The path to already-compiled schema types for linking while processing.
  `options` - Options specifying an error listener and/or validation behavior.
Throws:
  `XmlException`

#### compileXsd

    public static SchemaTypeSystem compileXsd(SchemaTypeSystem system,
                                              XmlObject[] schemas,
                                              SchemaTypeLoader typepath,
                                              XmlOptions options)
                                       throws XmlException

Returns the SchemaTypeSystem that results from augumenting the SchemaTypeSystem passed in by incrementally adding the given XML schema definitions.

These could be new definitions (if the Schema document is not recorded into the existing SchemaTypeSystem), modifications to the already existing definitions (if the Schema document is already recorded in the existing SchemaTypeSystem), or deletions (if the Schema document is already recorded in the existing SchemaTypeSystem and the new definitions are empty). The identity of documents is established using `XmlDocumentProperties.getSourceName()`, so if the caller choses to construct the Schema definitions using other methods than parsing an XML document, they should make sure that the names returned by that method are consistent with the caller's intent (add/modify).

The XmlObjects passed in should be w3c <schema> elements whose type is org.w3c.x2001.xmlSchema.Schema. (That is, schema elements in the XML namespace http://www.w3c.org/2001/XMLSchema.) Also org.w3c.x2001.xmlSchema.SchemaDocument is permitted.

The optional second argument is a SchemaTypeLoader which will be consulted for already-compiled schema types which may be linked while processing the given schemas.

The SchemaTypeSystem that is returned should be combined (via `typeLoaderUnion(org.apache.xmlbeans.SchemaTypeLoader...)`) with the typepath typeloader in order to create a typeloader that can be used for creating and validating instances.

Use the options parameter to specify the following:

- A collection instance that should be used as an error listener during compilation, as described in `XmlOptions.setErrorListener(java.util.Collection<org.apache.xmlbeans.XmlError>)`.
- Whether validation should not be done when building the SchemaTypeSystem, as described in `XmlOptions.setCompileNoValidation()`.

Parameters:
  `schemas` - The schema definitions from which to build the schema type system.
  `typepath` - The path to already-compiled schema types for linking while processing.
  `options` - Options specifying an error listener and/or validation behavior.
Throws:
  `XmlException`

#### compileXmlBeans

    public static SchemaTypeSystem compileXmlBeans(String name,
                                                   SchemaTypeSystem system,
                                                   XmlObject[] schemas,
                                                   BindingConfig config,

                                            throws XmlException

Returns the SchemaTypeSystem that results from augumenting the SchemaTypeSystem passed in by incrementally adding the given XML schema definitions.

These could be new definitions (if the Schema document is not recorded into the existing SchemaTypeSystem), modifications to the already existing definitions (if the Schema document is already recorded in the existing SchemaTypeSystem), or deletions (if the Schema document is already recorded in the existing SchemaTypeSystem and the new definitions are empty). The identity of documents is established using `XmlDocumentProperties.getSourceName()`, so if the caller choses to construct the Schema definitions using other methods than parsing an XML document, they should make sure that the names returned by that method are consistent with the caller's intent (add/modify).

The XmlObjects passed in should be w3c <schema> elements whose type is org.w3c.x2001.xmlSchema.Schema. (That is, schema elements in the XML namespace http://www.w3c.org/2001/XMLSchema.) Also org.w3c.x2001.xmlSchema.SchemaDocument is permitted.

The optional name argument is used to name the compiled schema type system. A randomly generated name will be used if the name is null.

The optional `BindingConfig` argument is used to control the shape of the generated code. A `BindingConfig` isn't used if `Filer` is null.

The optional SchemaTypeLoader argument will be consulted for already-compiled schema types which may be linked while processing the given schemas. If not specified, the context typeloader (as returned by `getContextTypeLoader()`) will be used.

The optional `Filer` argument is used to create new binary or source files which are the product of the compilation. If the Filer is null, the schema binaries (.xsb) files and source files won't be generated.

The SchemaTypeSystem that is returned should be combined (via `typeLoaderUnion(org.apache.xmlbeans.SchemaTypeLoader...)`) with the typepath typeloader in order to create a typeloader that can be used for creating and validating instances.

Use the options parameter to specify the following:

- A collection instance that should be used as an error listener during compilation, as described in `XmlOptions.setErrorListener(java.util.Collection<org.apache.xmlbeans.XmlError>)`.
- Whether validation should not be done when building the SchemaTypeSystem, as described in `XmlOptions.setCompileNoValidation()`.

Parameters:
  `name` - The type system name or null to use a randomly generated name.
  `system` - A pre-existing SchemaTypeSystem used in incremental compilation.
  `schemas` - The schema definitions from which to build the schema type system.
  `config` - The configuration controls the code generation shape.
  `typepath` - The path to already-compiled schema types for linking while processing.
  `filer` - The Filer instance used to create binary binding files and source text files.
  `options` - Options specifying an error listener and/or validation behavior.
Throws:
  `XmlException`
