Method Detail

getProxyInterfaces

public static Class<?>[] getProxyInterfaces(Class<?> claz)

Returns an array of all interfaces an lrmi based proxy to the specified class should implement

Parameters:

claz - proxy class

Returns:

an array of all interfaces an lrmi based proxy to the specified class should implement

getDeclaredRemoteInterfaces

public static List<Class<?>> getDeclaredRemoteInterfaces(Class<?> claz)

Returns a list of all java.rmi.Remote interfaces implemented supplied class.

Parameters:

claz - The class to get all java.rmi.Remote interfaces.

getDeclaredInterfaces

public static List<Class<?>> getDeclaredInterfaces(Class claz,
                                                   Class... assignableClasses)

Returns an array of all declared interfaces of desired class (super-classes comes an account). If assignableClasses is null all implemented interface will be added to array, otherwise only assignable classes.

Parameters:

claz - The class to get all interfaces.

createRemoteMethodCache

public static RemoteMethodCache createRemoteMethodCache(List<Class<?>> remoteInterfaces,
                                                        Map<String,Integer> methodMapping,
                                                        Map<String,LRMIMethodMetadata> overrideMethodsMetadata)

Returns a ~cache of sorted java.rmi.Remote methods of desired exported Remote object.

getMethodNameAndDescriptor

public static String getMethodNameAndDescriptor(IMethod m)

Returns a string consisting of the given method's name followed by its "method descriptor", as appropriate for use in the computation of the "method hash". See section 4.3.3 of The Java(TM) Virtual Machine Specification for the definition of a "method descriptor".

getMethodDisplayString

getMappingMethodDescriptor

public static Map<String,IMethod> getMappingMethodDescriptor(Class clazz)

Returns the cross instance/platform mapping table of desired class with method descriptors(method hash). Key: String method descriptor (method hash) Value: Method instance of provided class.
The method descriptor generates

Parameters:

clazz - the class to get mapping descriptors from.

Returns:

the mapping descriptor table.
