HandlerDefinition

public class HandlerDefinition implements java.io.Serializable(Code)

A HandlerDefinition defines a "handler" that may be invoked in the process of executing an event. A HandlerDefinition has an id, java method, input definitions, output definitions, and child handlers.

The java method to be invoked must have the following method signature:

public void beginDisplay(HandlerContext handlerCtx)

void above can return a value. Depending on the type of event, return values may be handled differently.

	Constructor

Method Detail

addChildHandler
public void addChildHandler(Handler desc)(Code)
	This method adds a Handler to the list of child handlers. Child Handlers are executed PRIOR to this handler executing. Parameters: desc - The Handler to add

addInputDef
public void addInputDef(IODescriptor desc)(Code)
	This method adds an IODescriptor to the list of input descriptors. These descriptors define the input parameters to this handler. Parameters: desc - The input IODescriptor to add

addOutputDef
public void addOutputDef(IODescriptor desc)(Code)
	This method adds an IODescriptor to the list of output descriptors. These descriptors define the output parameters to this handler. Parameters: desc - The IODescriptor to add

getChildHandlers
public List getChildHandlers()(Code)
	This method retrieves the List of child Handler. The List of child Handler for this handler.

getDescription
public String getDescription()(Code)
	For future tool support

getHandlerMethod
public Method getHandlerMethod()(Code)

getId
public String getId()(Code)
	This method returns the id for this handler.

getInputDef
public IODescriptor getInputDef(String name)(Code)
	This method returns the requested IODescriptor, null if not found.

getInputDefs
public Map getInputDefs()(Code)
	This method retrieves the Map of input IODescriptors. The Map of IODescriptors

getOutputDef
public IODescriptor getOutputDef(String name)(Code)
	This method returns the requested IODescriptor, null if not found.

getOutputDefs
public Map getOutputDefs()(Code)
	This method retrieves the Map of output IODescriptors. The Map of output IODescriptors

isStatic
public boolean isStatic()(Code)
	This method determines if the handler is static.

setChildHandlers
public void setChildHandlers(List childHandlers)(Code)
	This method sets the List of child Handlers for this HandlerDefinition. Parameters: childHandlers - The List of child Handler objects

setDescription
public void setDescription(String desc)(Code)
	For future tool support

setHandlerMethod

public void setHandlerMethod(String cls, String methodName)(Code)

This method sets the event handler (method) to be invoked. The method should be public and accept a prameter of type "HandlerContext" Example:

public void beginDisplay(HandlerContext handlerCtx)

Parameters:
cls - The full class name containing method
Parameters:
methodName - The method name of the handler within class

setHandlerMethod
public void setHandlerMethod(Method method)(Code)

setInputDefs
public void setInputDefs(Map inputDefs)(Code)
	This method sets the input IODescriptors for this handler. Parameters: inputDefs - The Map of IODescriptors

setOutputDefs
public void setOutputDefs(Map outputDefs)(Code)
	This method sets the output IODescriptors for this handler. Parameters: outputDefs - The Map of output IODescriptors
