Constructor Detail 

public XMLFilterImpl()
Construct an empty XML filter, with no parent.

This filter will have no parent: you must assign a parent before you start a parse or do any configuration with setFeature or setProperty.



Construct an XML filter with the specified parent.














Method Detail





setParent



Set the parent reader.

 this filter will obtain its events and to which it will pass its 
 configuration requests.  The parent may itself be another filter.


 
If there is no parent reader set, any attempt to parse
 or to set or get a feature or property will fail.














getParent




Get the parent reader.














setFeature


public void setFeature(java.lang.String name,
                       boolean state)



Set the state of a feature.

 
This will always fail if the parent is null.







            XMLReader recognizes the feature name but 









getFeature


public boolean getFeature(java.lang.String name)



Look up the state of a feature.

 
This will always fail if the parent is null.







            XMLReader recognizes the feature name but 









setProperty


public void setProperty(java.lang.String name,
                        java.lang.Object value)



Set the value of a property.

 
This will always fail if the parent is null.







            XMLReader recognizes the property name but 









getProperty


public java.lang.Object getProperty(java.lang.String name)



Look up the value of a property.







            XMLReader recognizes the property name but 







setEntityResolver



Set the entity resolver.








Parameters:
resolver - The new entity resolver.
Throws:
java.lang.NullPointerException - If the resolver









getEntityResolver




Get the current entity resolver.














setDTDHandler



Set the DTD event handler.








Parameters:
resolver - The new DTD handler.
Throws:
java.lang.NullPointerException - If the handler









getDTDHandler




Get the current DTD event handler.














setContentHandler



Set the content event handler.








Parameters:
resolver - The new content handler.
Throws:
java.lang.NullPointerException - If the handler









getContentHandler




Get the content event handler.














setErrorHandler



Set the error event handler.








Parameters:
handle - The new error handler.
Throws:
java.lang.NullPointerException - If the handler









getErrorHandler




Get the current error event handler.














parse

                  java.io.IOException




Parse a document.







            wrapping another exception.
java.io.IOException - An IO exception from the parser,
            possibly from a byte stream or character stream









parse


public void parse(java.lang.String systemId)
                  java.io.IOException




Parse a document.







            wrapping another exception.
java.io.IOException - An IO exception from the parser,
            possibly from a byte stream or character stream









resolveEntity


                                 java.lang.String systemId)
                                 java.io.IOException




Filter an external entity resolution.





            an exception during processing.
java.io.IOException - The client may throw an
            I/O-related exception while obtaining the









notationDecl


public void notationDecl(java.lang.String name,
