Description copied from interface: EvaluatablePathElement

Evaluate this key as if it is an write path element.

Specified by:

evaluate in interface EvaluatablePathElement

Parameters:

walkedPath - "up the tree" list of LiteralPathElements, that may be used by this key as it is computing

Returns:

String path element to use for write tree building

getExplicitArrayIndex

public Integer getExplicitArrayIndex()

isExplicitArrayIndex
