Class AbleTypedVariableCompoundLiteral

java.lang.Object
  com.ibm.able.data.AbleLiteral
      com.ibm.able.data.AbleTypedVariableCompoundLiteral

All Implemented Interfaces:

AbleRd, java.io.Serializable

public class AbleTypedVariableCompoundLiteral

extends AbleLiteral

This class performs a sequence of field access and method invocations starting on an AbleTypedVariable. This literal behaves somewhat differently from other AbleLiterals, in that is not strictly a constant, it invokes the same methods on the same typed variable, but the underlying Object being invoked may change during the course of a ruleset evaluation.

Any nested dot notation field references or method calls get parsed and turned into an instance of this class. Any number of arguments may appear in the source statement.

Field Detail

myTypedVariable

protected AbleTypedVariable myTypedVariable

                                 throws AbleDataException

Create a new Able data method object with the specified information. The initial value of this literal is null, and it remains null until this literal is requested to give up a value. At that time, the method is called to produce a value. Each time a value is requested from this literal, the method is recalled; be aware that the current value may thus change from time to time.

Parameters:

theTypedVariable - A typed variable that contains the following field.

theLiterals - A list of AbleRd objects whose runtime values will be passed to the user-defined function as arguments. Each converted argument will be a Boolean, a Double, a String, or an Object, depending on the type of each AbleRd object in the argument list. The list can be empty, but it must never be null.
