DocumentElementPreprocessor

public DocumentElementPreprocessor()

Constructs a DocumentElementPreprocessor.

Method Detail

addElementPreprocessor

public DocumentElementPreprocessor addElementPreprocessor(DocumentElementPreprocessor.ElementPreprocessor preprocessor)

Adds an DocumentElementPreprocessor.ElementPreprocessor to the DocumentElementPreprocessor.

Parameters:

preprocessor - the DocumentElementPreprocessor.ElementPreprocessor to add

Returns:

the DocumentElementPreprocessor (this) to support fluent-style calls

preprocess

public boolean preprocess(ProcessingContext context,
                          XmlElement xmlElement)
                   throws ConfigurationException

Performs pre-processing of the an XmlElement, optionally mutating it (or it's children) as required.

Implementations of this interface may traverse and/or perform any mutations on the specified XmlElement.

Note: It is illegal to modify an XmlElement outside the scope of the provided XmlElement. eg: Attempting to modify any of the parents of the provided XmlElement may result in undefined and unexpected behavior. Only mutations of the XmlElement itself or children is permitted.

Specified by:

preprocess in interface DocumentPreprocessor

Parameters:

context - the ProcessingContext in which the XmlElement is being pre-processed

xmlElement - the XmlElement to pre-process

Returns:

true if the specified XmlElement should be reconsidered either by this or other DocumentPreprocessors for re-preprocessing due to mutations on the XmlElement, false otherwise.

Throws:

ConfigurationException - if during pre-processing of the XmlElement a configuration issue was discovered (or if pre-processing fails for some reason)
