Interface XMLFilter

public interface XMLFilter extends XMLReader

Interface for an XML filter.

An XML filter is like an XML reader, except that it obtains its events from another XML reader rather than a primary source like an XML document or database. Filters can modify a stream of events as they pass on to the final application.

The XMLFilterImpl helper class provides a convenient base for creating SAX2 filters, by passing on all EntityResolver, DTDHandler, ContentHandler and ErrorHandler events automatically.

Get the parent reader.
abstract voidsetParent(XMLReader parent)

Method Detail

getParent

public abstract XMLReader getParent()
Get the parent reader.

This method allows the application to query the parent reader (which may be another filter). It is generally a bad idea to perform any operations on the parent reader directly: they should all pass through this filter.

Returns: The parent filter, or null if none has been set.

setParent

public abstract void setParent(XMLReader parent)
Set the parent reader.

This method allows the application to link the filter to a parent reader (which may be another filter). The argument may not be null.

Parameters: parent The parent reader.
