Interface IlrBinaryTester

All Superinterfaces:

Serializable

public interface IlrBinaryTester
extends Serializable

A binary tester for performing tests involving two values. Internally, each time an object of the class IlrBinaryTest is created, a binary tester is determined and attached to that object. The evaluate method can then be used to perform the test operation.

Field Summary

static int	EQUAL An equality test between two values.
static int	GREATER_OR_EQUAL The first value is tested to be greater than or equal to the second value.
static int	GREATER_THAN The first value is tested to be greater than the second value.
static int	IN The first value is tested to be contained by the second value.
static int	LESS_OR_EQUAL The first value is tested to be less than or equal to the second value.
static int	LESS_THAN The first value is tested to be less than the second value.
static int	MATCH The first value (rule property) is tested to match (be equal to) the second value.
static int	MATCH_DOWN The first value (rule property) is tested to be in the path formed from the second value to the hierarchy leaves.
static int	MATCH_UP The first value (rule property) is tested to be in the path formed from the hierarchy root to the second value.
static int	MATCH_UPDOWN The first value (rule property) is tested to either match up or match down the second value.
static int	NOT_EQUAL A nonequality test between two values.
static int	NOT_IN The first value is tested to be not contained by the second value.

Method Summary

boolean	evaluate(Object arg1, Object arg2) Performs the test operation.
int	getKind() Gets the kind of the binary test.

Method Detail

getKind

int getKind()

Gets the kind of the binary test. The kind of the test is defined by the integer constants of this interface.

Returns:

The kind of the binary test.

evaluate

boolean evaluate(Object arg1,
                 Object arg2)

Performs the test operation. It takes two values as arguments and returns a Boolean value as the result. If the arguments are of primitive types, they should be wrapped using their respective wrapping class to use this method. If the result is a primitive type, it is also wrapped using the corresponding wrapping type.

Parameters:

arg1 - The first argument of the operation.

arg2 - The second argument of the operation.

Returns:

A Boolean value, the result of the test operation.
