ilog.rules.factory
Class IlrBinaryTest

java.lang.Object
  ilog.rules.factory.IlrBaseTest
      ilog.rules.factory.IlrBinaryTest

All Implemented Interfaces:

ilog.rules.factory.IlrSourceElement, IlrTest, Serializable

Direct Known Subclasses:

IlrPropertyMatchTest

public class IlrBinaryTest
extends IlrBaseTest

This class represents a binary test of the rule language. A binary test uses two values and performs a test between those values. The kind of test is specified by the field kind. The possible values of this field are defined in IlrBinaryTester. The test itself is performed by a IlrBinaryTester, which is returned by the method getTester(). If this method returns a null object, the current binary test is not a valid test expression.

Warning: Serialized objects of this class will not be compatible with future releases. The current serialization support is appropriate for short term storage or RMI between applications running the same version of IBM Decision Server.

Constructor Detail

IlrBinaryTest

public IlrBinaryTest(int kind,
                     IlrValue first,
                     IlrValue second)

Constructs a binary test. This test involves two values.

Parameters:

kind - The kind of test, as defined in IlrBinaryTester. The possible values are those between IlrBinaryTester.EQUAL and IlrBinaryTester.NOT_IN. In case an incorrect value is given, an IllegalArgumentException is thrown.

first - The first argument value.

second - The second argument value.

IlrBinaryTest

protected IlrBinaryTest()

Method Detail

getKind

public final int getKind()

Gets the kind of test. The possible values are defined in IlrBinaryTester.

Returns:

The kind of this test.

setKind

public void setKind(int kind)

Sets the kind of test.

Parameters:

kind - The possible values are defined in IlrBinaryTester.

getFirstArgument

public final IlrValue getFirstArgument()

Gets the first argument value involved in this test.

Returns:

The first argument value involved in this test.

setFirstArgument

public final void setFirstArgument(IlrValue first)

Changes the first argument value involved in this test.

Parameters:

first - The first argument value involved in this test.

getSecondArgument

public final IlrValue getSecondArgument()

Gets the second argument value involved in this test.

Returns:

The second argument value involved in this test.

setSecondArgument

public final void setSecondArgument(IlrValue second)

Changes the second argument value involved in this test.

Parameters:

second - The second argument value involved in this test.

getTester

public IlrBinaryTester getTester()

Determines and returns the binary tester used to perform the test. The tester is determined using the types of the arguments and the kind of the test. If this method returns null, the test is not a valid test expression.

Returns:

A binary tester, or null if the test is not valid.

exploreTest

public Object exploreTest(IlrFactoryExplorer explorer)

Explores this binary test using a factory explorer and returns an object as a result.

Parameters:

explorer - The factory explorer.

Returns:

An object which represents the result of the exploration, or null if the method does not return a value.
