All Implemented Interfaces:

DynReflect

public class DynReflectImpl
extends Object
implements DynReflect

A base for implementating "dynamic" reflection that abstracts how to find methods and constructors, and how to produce functions that invoke them.

Constructor Detail

DynReflectImpl

public DynReflectImpl()

Default constructor, which leaves the helper mechanisms unspecified.

The mechanisms to use for finding methods and constructors (ReflectFinder) and for producing a method or constructor invoker (ReflectFactory) are left unspecified when this default constructor is used. Therefore, they must be specified using the appropriate setters: setReflectFinder(info.javelot.functionalj.reflect.helper.ReflectFinder) and setReflectFactory(info.javelot.functionalj.reflect.helper.ReflectFactory).

DynReflectImpl

public DynReflectImpl(ReflectFinder p_finder,
                      ReflectFactory p_factory,
                      ReflectParameters p_rp)

Constructor that accepts the mechanisms used for reflection.

Parameters:

p_finder - the mechanism used for finding methods and constructors.

p_factory - the mechanism used for producing a method or constructor invoker.

p_rp - the mechanism used for finding elements that are compatible with parameters.

Method Detail

setReflectFinder

public void setReflectFinder(ReflectFinder p_finder)

Sets the mechanism to use for finding methods and constructors.

setReflectFactory

public void setReflectFactory(ReflectFactory p_factory)

Sets the mechanism to use for producing a method or constructor invoker.

setReflectParameters

public void setReflectParameters(ReflectParameters p_rp)

Sets the mechanism to use for finding elements that are compatible with parameters.

constructor

public FunctionN constructor(Class p_class)
                      throws FunctionException

Description copied from interface: DynReflect

Produces a function that creates an instance of the specified class, using a constructor.

Specified by:

constructor in interface DynReflect

Parameters:

p_class - an instance of this class will be created by the function. The parameters to the constructor will be the same as the parameters provided to the function.

Returns:

a function that passes its parameters to the constructor and returns an instance of the class.

Throws:

FunctionException - thrown if a matching constructor was not found.

constructor

public FunctionN constructor(String p_class)
                      throws FunctionException

Description copied from interface: DynReflect

Version of DynReflect.constructor(Class) that accepts a String to specify the class by name.

Specified by:

constructor in interface DynReflect

Throws:

FunctionException

instanceFunction

public FunctionN instanceFunction(Class p_class,
                                  String p_name)
                           throws FunctionException

Description copied from interface: DynReflect

Produces a function that invokes the instance method of specified class which has the specified name, using the parameters passed to the function.

Specified by:

instanceFunction in interface DynReflect

Parameters:

p_class - the class which contains the instance method to be invoked by the produced function.

p_name - the name of the method.

Returns:

a function that invokes the method on the object that is specified as its first parameter, passing the rest of its parameters to the method and returning the result of the invocation.

Throws:

FunctionException - thrown if a matching instance method was not found.
