Constructor Detail

AutoInvoke

public AutoInvoke(AutoEngineInfo thisAutoInfo,
                  java.util.ArrayList thisParamList,
                  ObjectsMap thisObjectsMap,
                  Service thisService)

Create a new instance of AutoInvoke and set the method variables and objects.

Parameters:

thisAutoInfo - the process script elements parsed into their actual objects and definitions.

thisParamList - an external set of KeyValue objects that can replace named or tagged fields in the method parameter lists. If empty or no match, then nothing gets changed.

thisObjectsMap - mapping of variable names to instances. This method can ad more variables, but should be for the method invocation only, so immediately cloned.

thisService - the service to execute on.

Method Detail

invokeMethod

public AutoOut invokeMethod()
                     throws LicasException,
                            java.lang.Exception

Invoke the method in the autoInfo object, making variable replacements first. From that object, the evaluator is used to execute the method. The evaluation can be compared to the function. The input can be used to replace a tagged Const.QUERY parameter and so should be an XML element. If the reply is OK, the autoInfo effOutput is returned as the next set of actions.

Returns:

the result of the evaluation. This is the effector list of the input parameter if the evaluation is true, or an empty list if it is false. Evaluating to true can include matching exactly to an XML description, or just have any result, for example, by using a checkReply method.

Throws:

LicasException - for a licas-specific mapping problem.

java.lang.Exception - any error.

isLicasCall

protected boolean isLicasCall(java.lang.Object evaluator)

Return true if the evaluator object indicates a licas service that should be invoked.

Parameters:

evaluator - the evaluator object.

Returns:

true if it indicates a licas service to perform the evaluation.

isWsCall

protected boolean isWsCall(java.lang.Object evaluator)

Return true if the evaluator object indicates a web service that should be invoked.

Parameters:

evaluator - the evaluator object.

Returns:

true if it indicates a web service to perform the evaluation.
