Method Detail

getConstraints

public IConstraint[] getConstraints()

Return the IConstraints for this HavingNode.

toString

public String toString(int indent)

Description copied from class: CoreBaseBOp

The contract of this method at this level is under-specified. Sub-classes may choose between: - return a string representation of the object, similar to the use of CoreBaseBOp.toString() Or: - return a pretty-print representation of the object with indent Note that the former contract may or may not include recursive descent through a tree-like object, whereas the latter almost certainly does.
