TypeInfoProvider

abstract class TypeInfoProvider

kotlin.Any
↳	javax.xml.validation.TypeInfoProvider

This class provides access to the type information determined by ValidatorHandler.

Some schema languages, such as W3C XML Schema, encourages a validator to report the "type" it assigns to each attribute/element. Those applications who wish to access this type information can invoke methods defined on this "interface" to access such type information.

Implementation of this "interface" can be obtained through the ValidatorHandler#getTypeInfoProvider() method.

Summary

Protected constructors
`TypeInfoProvider()` Constructor for the derived class.

Public methods
abstract TypeInfo!	`getAttributeTypeInfo(index: Int)` Returns the immutable `TypeInfo` object for the specified attribute of the current element.
abstract TypeInfo!	`getElementTypeInfo()` Returns the immutable `TypeInfo` object for the current element.
abstract Boolean	`isIdAttribute(index: Int)` Returns true if the specified attribute is determined to be ID.
abstract Boolean	`isSpecified(index: Int)` Returns false if the attribute was added by the validator.

protected TypeInfoProvider()

Constructor for the derived class.

The constructor does nothing.

Public methods

getAttributeTypeInfo

Added in API level 8

abstract fun getAttributeTypeInfo(index: Int): TypeInfo!

Returns the immutable TypeInfo object for the specified attribute of the current element.

The method may only be called by the startElement event of the org.xml.sax.ContentHandler that the application sets to the ValidatorHandler.

Parameters
`index`	Int: The index of the attribute. The same index for the `org.xml.sax.Attributes` object passed to the startElement callback.

Return
`TypeInfo!`	An immutable `TypeInfo` object that represents the type of the specified attribute. Note that the caller can keep references to the obtained `TypeInfo` longer than the callback scope. Otherwise, this method returns null if the validator is unable to determine the type.

Exceptions
`java.lang.IndexOutOfBoundsException`	If the index is invalid.
`java.lang.IllegalStateException`	If this method is called from other `org.xml.sax.ContentHandler` methods.

getElementTypeInfo

Added in API level 8

abstract fun getElementTypeInfo(): TypeInfo!

Returns the immutable TypeInfo object for the current element.

The method may only be called by the startElement and endElement event of the org.xml.sax.ContentHandler that the application sets to the ValidatorHandler.

Return
`TypeInfo!`	An immutable `TypeInfo` object that represents the type of the current element. Note that the caller can keep references to the obtained `TypeInfo` longer than the callback scope. Otherwise, this method returns null if the validator is unable to determine the type of the current element for some reason (for example, if the validator is recovering from an earlier error.)

Exceptions
`java.lang.IllegalStateException`	If this method is called from other `org.xml.sax.ContentHandler` methods.

isIdAttribute

Added in API level 8

abstract fun isIdAttribute(index: Int): Boolean

Returns true if the specified attribute is determined to be ID.

Exactly how an attribute is "determined to be ID" is up to the schema language. In case of W3C XML Schema, this means that the actual type of the attribute is the built-in ID type or its derived type.

A javax.xml.parsers.DocumentBuilder uses this information to properly implement org.w3c.dom.Attr#isId().

The method may only be called by the startElement event of the org.xml.sax.ContentHandler that the application sets to the ValidatorHandler.

Parameters
`index`	Int: The index of the attribute. The same index for the `org.xml.sax.Attributes` object passed to the startElement callback.

Return
`Boolean`	true if the type of the specified attribute is ID.

Exceptions
`java.lang.IndexOutOfBoundsException`	If the index is invalid.
`java.lang.IllegalStateException`	If this method is called from other `org.xml.sax.ContentHandler` methods.

isSpecified

Added in API level 8

abstract fun isSpecified(index: Int): Boolean

Returns false if the attribute was added by the validator.

This method provides information necessary for a javax.xml.parsers.DocumentBuilder to determine what the DOM tree should return from the org.w3c.dom.Attr#getSpecified() method.

The method may only be called by the startElement event of the org.xml.sax.ContentHandler that the application sets to the ValidatorHandler.

A general guideline for validators is to return true if the attribute was originally present in the pipeline, and false if it was added by the validator.

Parameters
`index`	Int: The index of the attribute. The same index for the `org.xml.sax.Attributes` object passed to the startElement callback.

Return
`Boolean`	true if the attribute was present before the validator processes input. false if the attribute was added by the validator.

Exceptions
`java.lang.IndexOutOfBoundsException`	If the index is invalid.
`java.lang.IllegalStateException`	If this method is called from other `org.xml.sax.ContentHandler` methods.
