Specified by:

getDescription in class AbstractStructuredFieldPosition

linkSelf

public boolean linkSelf()

Description copied from interface: StructuredFieldPosition

Normally paths would require onlt parent chaining. for some it is parent and child chaining.

linkSelf in interface StructuredFieldPosition

Overrides:

linkSelf in class AbstractStructuredFieldPosition

Returns:

isTerminal

public boolean isTerminal()

Description copied from interface: StructuredFieldPosition

If this position is last in the chain and it is terminal it will ensure it is an exact match for the length of the chain found. If false, it will effectively allow prefix mathces for the likes of descendant-and-below style queries.

Specified by:

isTerminal in interface StructuredFieldPosition

Overrides:

isTerminal in class AbstractStructuredFieldPosition

Returns:
