Method Detail

isEquivalent

public boolean isEquivalent(Clause clause,
                            Clause clause1)

Compares two clauses for equivalence suitable for use in Issue Navigator; e.g. clauses that may actually be logically equivalent, but are structured differently, would fail this test. Note that ordering is not important within MultiClauses

It is assumed that both clauses have been normalised before being passed in, so that their structures are as similar as possible.

Parameters:

clause - a normalised Clause; never null

clause1 - a normalised Clause; never null

Returns:

true if the clauses are equivalent; false otherwise.
