intersect

public ClauseContext intersect(Set<? extends ClauseContext> childClauseContexts)

Returns:

the intersection of ClauseContext's that were passed in.

union

public ClauseContext union(Set<? extends ClauseContext> childClauseContexts)

childClauseContexts - the child clause contexts to union, must never be null or contain null elements
