All Implemented Interfaces:

IProcessingContext

public final class Arguments
extends AbstractDialectAwareProcessingContext

Objects of this class contain all the required arguments for template processing.

These objects are created internally by the Template Engine in order to provide processors with all the information they might need for performing their tasks.

Arguments include many attributes, among which some should be used internally only, and never by developers of attribute/element processors. Public attributes are:

• The Template Engine configuration (Configuration): getConfiguration()
• The template name: getTemplateName()
• The Context (IContext): AbstractProcessingContext.getContext()
• The current map of ID Counts (used for adding a unique index to repeated id attributes): getIdCounts()
• The Expression roots:
  • For normal (non selected) evaluation (${...} in standard dialect): AbstractProcessingContext.getExpressionEvaluationRoot()
  • For selected evaluation (*{...} in standard dialect): AbstractProcessingContext.getExpressionSelectionEvaluationRoot()
• Information about whether processing non-element nodes is allowed at a specific point of a template execution or not (default is to process only elements).

Arguments

public Arguments(TemplateEngine templateEngine,
                 TemplateProcessingParameters templateProcessingParameters,
                 TemplateResolution templateResolution,
                 TemplateRepository templateRepository,
                 Document document)

Create a new Arguments instance.

Mainly for internal use. Should not be called directly except for testing purposes or when processing a template (e.g. a fragment) using the TemplateEngine from a element/attribute processor.

Parameters:

templateProcessingParameters - the template processing parameters.

templateResolution - the template resolution object.

templateRepository - the template repository in use.

document - the parsed document.

Method Detail

getTemplateEngine

public TemplateEngine getTemplateEngine()

Returns the Template Engine associated to this Arguments instance.

Returns:

the template processing parameters

Since:

2.0.14

getTemplateProcessingParameters

public TemplateProcessingParameters getTemplateProcessingParameters()

Returns the Template Processing Parameters used for resolving and parsing the template being processed.

Returns:

the template processing parameters

getConfiguration

public Configuration getConfiguration()

Returns the Template Engine configuration being used for processing templates.

Returns:

the configuration

getTemplateResolution

public TemplateResolution getTemplateResolution()

Returns the template resolution object corresponding to the template currently being processed.
