Method Detail

getNodeShape

public ShowlNodeShape getNodeShape()

flatten

public List<ShowlPropertyShape> flatten()

Flatten this list if possible. A ShowlUniqueKeyCollection can be flattened only if there is a single way to identify the associated NodeShape. In other words, the collection can be flattened if it contains a single key, and each ShowlUniqueKeyCollection nested within it also contains a single key.

Returns:

A flat list of PropertyShape entities contained within this collection provided it can be flattened, and null otherwise.

findMatch

public ShowlUniqueKey findMatch(ShowlUniqueKey pattern)
