Class MapSrcProcessor

java.lang.Object

jetbrains.mps.generator.impl.MapSrcProcessor

All Implemented Interfaces:

NodePostProcessor

Direct Known Subclasses:

MapSrcProcessor.MapSrcMacroProcessorInterpreted

public abstract class MapSrcProcessor
extends Object
implements NodePostProcessor

Default implementation of NodePostProcessor, with default implementation. Left abstract to stress there's no value in this class unless NodePostProcessor.substitute() and/or NodePostProcessor.postProcess(SNode) are overridden.

Constructor Detail

MapSrcProcessor

protected MapSrcProcessor(@NotNull
                          SNodeReference templateNode,
                          @NotNull
                          SNode outputAnchor,
                          @NotNull
                          TemplateContext context)

Method Detail

getTemplateNode

@NotNull
public final SNodeReference getTemplateNode()

Specified by:

getTemplateNode in interface NodePostProcessor

Returns:

pointer to the post-processing origin (e.g. MapSrcMacro) for log/navigation purposes.

getOutputAnchor

@NotNull
public final SNode getOutputAnchor()

Specified by:

getOutputAnchor in interface NodePostProcessor

Returns:

node in output model that is subject to substitute and/or post-processing

substitute

@NotNull
public SNode substitute()
                 throws GenerationFailureException

Default implementation returns getOutputAnchor()

Specified by:

substitute in interface NodePostProcessor

Returns:

generally shall supply a new node to replace output mode. Shall return NodePostProcessor.getOutputAnchor() to skip the substitution step.

Throws:

GenerationFailureException

postProcess

public void postProcess(@NotNull
                        SNode outputNode)
                 throws GenerationFailureException

Default implementation does nothing

Specified by:

postProcess in interface NodePostProcessor

Parameters:

outputNode - node in output model to process (outcome of NodePostProcessor.substitute() call, even if it gave NodePostProcessor.getOutputAnchor()).

Throws:

GenerationFailureException

getTemplateContext

@NotNull
public TemplateContext getTemplateContext()

Specified by:

getTemplateContext in interface NodePostProcessor

Returns:

context this post-processing code has been instantiated in
