Method Detail

wantTag

public abstract boolean wantTag(Tag t)

Decide whether this tag should be aggregated by this aggregator.

considerTag

public abstract void considerTag(Tag t,
                                 Unit u,
                                 LinkedList<Tag> tags,
                                 LinkedList<Unit> units)

Aggregate the given tag assigned to the given unit

aggregatedName

public abstract String aggregatedName()

Return name of the resulting aggregated tag.

internalTransform

protected void internalTransform(Body b,
                                 String phaseName,
                                 Map<String,String> options)

Description copied from class: BodyTransformer

This method is called to perform the transformation itself. It is declared abstract; subclasses must implement this method by making it the entry point to their actual Body transformation.

Specified by:

internalTransform in class BodyTransformer

Parameters:

b - the body on which to apply the transformation

phaseName - the phasename for this transform; not typically used by implementations.

options - the actual computed options; a combination of default options and Scene specified options.

fini

public void fini()

Called after all tags for a method have been aggregated.
