net.sf.saxon.event.ReceivingContentHandler

All Implemented Interfaces:

SourceLocator, LocationProvider, SaxonLocator, SourceLocationProvider, ContentHandler, DTDHandler, LexicalHandler, Locator

Direct Known Subclasses:

IdentityTransformerHandler, TemplatesHandlerImpl, TransformerHandlerImpl

public class ReceivingContentHandler
extends Object
implements ContentHandler, LexicalHandler, DTDHandler, SaxonLocator, SourceLocationProvider

ReceivingContentHandler is a glue class that provides a standard SAX ContentHandler interface to a Saxon Receiver. To achieve this it needs to map names supplied as strings to numeric name codes, for which purpose it needs access to a name pool. The class also performs the function of assembling adjacent text nodes.

The class was previously named ContentEmitter.

Constructor Details

ReceivingContentHandler

public ReceivingContentHandler()

create a ReceivingContentHandler and initialise variables

Method Details

reset

public void reset()

Set the ReceivingContentHandler to its initial state, except for the local name cache, which is retained

setIgnoreIgnorableWhitespace

public void setIgnoreIgnorableWhitespace(boolean ignore)

Set whether "ignorable whitespace" should be ignored. This method is effective only if called after setPipelineConfiguration, since the default value is taken from the configuration.

isIgnoringIgnorableWhitespace

public boolean isIgnoringIgnorableWhitespace()

Determine whether "ignorable whitespace" is ignored. This returns the value that was set using setIgnoreIgnorableWhitespace(boolean) if that has been called; otherwise the value from the configuration.
