Method Details

getSupportedTypes

public int getSupportedTypes()

Specified by:

getSupportedTypes in class Comparison

evaluateBooleanImpl

protected boolean evaluateBooleanImpl(VMXState vm)

Overrides:

evaluateBooleanImpl in class Expression

getPromotedType

public int getPromotedType(Expression expr1,

Description copied from class: Expression

Determines the type id (see TypeId) of the binarily promoted type of the operands expr1 and expr2 (binary promotion is defined by the Java Language Specification, it includes unboxing).

Overrides:

getPromotedType in class Expression

Parameters:

expr1 - first operand

Returns:

type id of promoted type

writeConditional

public int writeConditional(BytecodeWriter writer,
 org.objectweb.asm.Label falseLabel,
 org.objectweb.asm.Label trueLabel)

Overrides:

writeConditional in class Expression
