| ↳ | 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
getTypeInfoProvider() method.

Constructor for the derived class.
The constructor does nothing.
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 ContentHandler that the application sets to the
ValidatorHandler.
| index | The index of the attribute. The same index for
the Attributes object passed to the
startElement callback. |
|---|
| IndexOutOfBoundsException | If the index is invalid. |
|---|---|
| IllegalStateException | If this method is called from other ContentHandler
methods. |
Returns the immutable TypeInfo object for the current element.
The method may only be called by the startElement and endElement event of
the ContentHandler that the application sets to the
ValidatorHandler.
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.)
| IllegalStateException | If this method is called from other ContentHandler
methods. |
|---|
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 DocumentBuilder uses this information
to properly implement isId().
The method may only be called by the startElement event of
the ContentHandler that the application sets to the
ValidatorHandler.
| index | The index of the attribute. The same index for
the Attributes object passed to the
startElement callback. |
|---|
| IndexOutOfBoundsException | If the index is invalid. |
|---|---|
| IllegalStateException | If this method is called from other ContentHandler
methods. |
Returns false if the attribute was added by the validator.
This method provides information necessary for
a DocumentBuilder to determine what
the DOM tree should return from the getSpecified() method.
The method may only be called by the startElement event of
the 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.
| index | The index of the attribute. The same index for
the Attributes object passed to the
startElement callback. |

| IndexOutOfBoundsException | If the index is invalid. |
