New Revision: 1089
Added:
trunk/engine/src/test/java/com/metamatrix/query/sql/lang/TestJoinPredicate.java
Modified:
trunk/engine/src/main/java/com/metamatrix/query/sql/lang/JoinPredicate.java
trunk/engine/src/test/java/com/metamatrix/query/parser/TestParser.java
Log:
TEIID-695: Equality comparison of JoinPredicate returns true even when JoinPredicate criteria is different
Fixed JoinPredicate.equals(Object) method to compare its own criteria to the Object's criteria instead of comparing its own criteria to itself.
Added TestJoinPredicate UnitTest to cover equality checks on JoinPredicate object.
Fixed TestParser to build JoinPredicate in the same manner that the Parser is building it during parsing of a query which contains JoinPredicate.
