• java.lang.Object

Fields Summary

Constructors Summary
protected TypeInfoProvider() Constructor for the derived class. The constructor does nothing.

Methods Summary
public abstract org.w3c.dom.TypeInfo	getAttributeTypeInfo(int index) Returns the immutable {@link TypeInfo} object for the specified attribute of the current element. The method may only be called by the startElement event of the {@link org.xml.sax.ContentHandler} that the application sets to the {@link ValidatorHandler}. param index The index of the attribute. The same index for the {@link org.xml.sax.Attributes} object passed to the startElement callback. throws IndexOutOfBoundsException If the index is invalid. throws IllegalStateException If this method is called from other {@link org.xml.sax.ContentHandler} methods. return An immutable {@link TypeInfo} object that represents the type of the specified attribute. Note that the caller can keep references to the obtained {@link TypeInfo} longer than the callback scope. Otherwise, this method returns null if the validator is unable to determine the type.
public abstract org.w3c.dom.TypeInfo	getElementTypeInfo() Returns the immutable {@link TypeInfo} object for the current element. The method may only be called by the startElement event of the {@link org.xml.sax.ContentHandler} that the application sets to the {@link ValidatorHandler}. throws IllegalStateException If this method is called from other {@link org.xml.sax.ContentHandler} methods. return An immutable {@link TypeInfo} object that represents the type of the current element. Note that the caller can keep references to the obtained {@link 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.)
public abstract boolean	isIdAttribute(int index) Returns true if the specified attribute is determined to be ID. Exacly 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 {@link javax.xml.parsers.DocumentBuilder} uses this information to properly implement {@link org.w3c.dom.Attr#isId()}. The method may only be called by the startElement event of the {@link org.xml.sax.ContentHandler} that the application sets to the {@link ValidatorHandler}. param index The index of the attribute. The same index for the {@link org.xml.sax.Attributes} object passed to the startElement callback. throws IndexOutOfBoundsException If the index is invalid. throws IllegalStateException If this method is called from other {@link org.xml.sax.ContentHandler} methods. return true if the type of the specified attribute is ID.
public abstract boolean	isSpecified(int index) Returns false if the attribute was added by the validator. This method provides information necessary for a {@link javax.xml.parsers.DocumentBuilder} to determine what the DOM tree should return from the {@link org.w3c.dom.Attr#getSpecified()} method. The method may only be called by the startElement event of the {@link org.xml.sax.ContentHandler} that the application sets to the {@link 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. param index The index of the attribute. The same index for the {@link org.xml.sax.Attributes} object passed to the startElement callback. throws IndexOutOfBoundsException If the index is invalid. throws IllegalStateException If this method is called from other {@link org.xml.sax.ContentHandler} methods. return true if the attribute was present before the validator processes input. false if the attribute was added by the validator.
