Nested Class Summary

Nested Classes

Modifier and Type	Interface	Description
static class	Generics.GenericsHierarchy	Stores the type parameters for a class and, for parameters passed to super classes, the corresponding super class type parameters.
static class	Generics.GenericType	Stores a type and its type parameters, recursively.

Method Detail

buildHierarchy

Generics.GenericsHierarchy buildHierarchy(Class type)

Builds a Generics.GenericsHierarchy for the specified type.

pushGenericType

void pushGenericType(Generics.GenericType fieldType)

Sets the type that is currently being serialized. Must be balanced by popGenericType(). Between those calls, the type parameters are returned by nextGenericTypes() and nextGenericClass().

popGenericType

void popGenericType()

Removes the generic types being tracked since the corresponding pushGenericType(GenericType). This is safe to call even if pushGenericType(GenericType) was not called.

nextGenericTypes

Generics.GenericType[] nextGenericTypes()

Returns the current type parameters and pushes the next level of type parameters for subsequent calls. Must be balanced by popGenericType() (optional if null is returned). If multiple type parameters are returned, the last is used to advance to the next level of type parameters.

nextGenericClass() is easier to use when a class has a single type parameter. When a class has multiple type parameters, pushGenericType(GenericType) must be used for all except the last parameter.

Returns:

May be null.

nextGenericClass

Class nextGenericClass()

Resolves the first type parameter and returns the class, or null if it could not be resolved or there are no type parameters. Uses nextGenericTypes(), so must be balanced by popGenericType() (optional if null is returned).

This method is intended for ease of use when a class has a single type parameter.

Returns:

May be null.

pushTypeVariables

int pushTypeVariables(Generics.GenericsHierarchy hierarchy,
                      Generics.GenericType[] args)

Stores the types of the type parameters for the specified class hierarchy. Must be balanced by popTypeVariables(int) if >0 is returned.

Parameters:

args - May contain null for type arguments that aren't known.

Returns:

The number of entries that were pushed.

popTypeVariables

void popTypeVariables(int count)

Removes the number of entries that were pushed by pushTypeVariables(GenericsHierarchy, GenericType[]).

Parameters:

count - Must be even.

resolveTypeVariable

Class resolveTypeVariable(TypeVariable typeVariable)

Returns the class for the specified type variable, or null if it is not known.

Returns:

May be null.

getGenericTypesSize

int getGenericTypesSize()

Returns the number of generic types currently tracked
