com.ibm.websphere.sca.mq.selector
Class MQFunctionSelector

java.lang.Object
  extended by com.ibm.websphere.sca.mq.selector.MQFunctionSelector
All Implemented Interfaces:
commonj.connector.runtime.FunctionSelector

public abstract class MQFunctionSelector
extends java.lang.Object
implements commonj.connector.runtime.FunctionSelector

A helper class which makes it easier to write FunctionSelectors for use with WMQ Exports.

The commonj.connection.runtime.FunctionSelector interface provides a single method which takes an array of arbitrary objects as a solitary argument.

MQFunctionSelector implements this method by calling an abstract method with a more descriptive argument list. An implementation of MQFunctionSelector will implement the new abstract method with the descriptive argument list.

generateEISFunctionName

public final java.lang.String generateEISFunctionName(java.lang.Object[] arg)
                                               throws commonj.connector.runtime.SelectorException
Given an array of arguments, returns the selected native method name.

This implementation calls the more descriptive, abstract method, and is an implementation of the generateEISFunctionName method from commonj.connector.runtime.FunctionSelector. An implementation of this MQFunctionSelector interface is not required to override this method.

Specified by:
generateEISFunctionName in interface commonj.connector.runtime.FunctionSelector
Returns:
A string containing the native method name.
Throws:
commonj.connector.runtime.SelectorException

A more descriptive WMQ-specific method to extract a native method name using the FunctionSelector interface.

Implement this method to provide a native function name from the contents of a WMQ message by extracting the relevant data from the provided WMQ-centric parameters.

Returns:
A string containing the native method name.
Throws:
java.io.IOException
commonj.connector.runtime.SelectorException
