Method Detail

setUp

protected void setUp()
              throws Exception

Overrides:

setUp in class TestCase

Throws:

Exception

check

void check(Boolean encapsulateType,
           RexNode node,
           String expected)

testPreTests

public void testPreTests()

testNonBooleans

public void testNonBooleans()

testOrUnchanged

public void testOrUnchanged()

the or operator should pass through unchanged since e.g. x OR y should return true if x=null and y=true if it was transformed into something like (x ISNOTNULL) AND (y ISNOTNULL) AND (x OR y) an incorrect result could be produced

testSimpleAnd

public void testSimpleAnd()

testSimpleEquals

public void testSimpleEquals()

testSimpleNotEquals

public void testSimpleNotEquals()

testSimpleGreaterThan

public void testSimpleGreaterThan()

testSimpleGreaterEquals

public void testSimpleGreaterEquals()

testSimpleLessThan

public void testSimpleLessThan()

testSimpleLessEqual

public void testSimpleLessEqual()

testOptimizeNonNullLiterals

public void testOptimizeNonNullLiterals()

testSimpleIdentifier

public void testSimpleIdentifier()

testMixed1

public void testMixed1()

testMixed2
