Interface EventConsumer
- CallFilter, Consumer, DomConsumer, EventFilter, LinkFilter, NSFilter, TeeConsumer, TextConsumer, ValidationConsumer, WellFormednessFilter, XIncludeFilter, XsltFilter
Collects the event consumption apparatus of a SAX pipeline stage.
Consumers which permit some handlers or other characteristics to be
configured will provide methods to support that configuration.
Two important categories of consumers include
filters, which
process events and pass them on to other consumers, and
terminus
(or
terminal) stages, which don't pass events on. Filters are not
necessarily derived from the
EventFilter class, although that
class can substantially simplify their construction by automating the
most common activities.
Event consumers which follow certain conventions for the signatures
of their constructors can be automatically assembled into pipelines
by the
PipelineFactory class.
getProperty
public Object getProperty(String id)
throws SAXNotRecognizedException This method works like the SAX2 XMLReader method of the same name,
and is used to retrieve the optional lexical and declaration handlers
in a pipeline.
id - This is a URI identifying the type of property desired.
- The value of that property, if it is defined.
setErrorHandler
public void setErrorHandler(ErrorHandler handler)
This method provides a filter stage with a handler that abstracts
presentation of warnings and both recoverable and fatal errors.
Most pipeline stages should share a single policy and mechanism
for such reports, since application components require consistency
in such activities. Accordingly, typical responses to this method
invocation involve saving the handler for use; filters will pass
it on to any other consumers they use.
handler - encapsulates error handling policy for this stage
