Method Detail

buildHierarchy

public Generics.GenericsHierarchy buildHierarchy(Class type)

Description copied from interface: Generics

Builds a Generics.GenericsHierarchy for the specified type.

Specified by:

buildHierarchy in interface Generics

pushGenericType

public void pushGenericType(Generics.GenericType fieldType)

Description copied from interface: Generics

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

Specified by:

pushGenericType in interface Generics

popGenericType

public void popGenericType()

Description copied from interface: Generics

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

Specified by:

popGenericType in interface Generics

nextGenericTypes

public Generics.GenericType[] nextGenericTypes()

Description copied from interface: Generics

Returns the current type parameters and pushes the next level of type parameters for subsequent calls. Must be balanced by Generics.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.

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

Specified by:

nextGenericTypes in interface Generics

Returns:

May be null.

nextGenericClass

public Class nextGenericClass()

Description copied from interface: Generics

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

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

Specified by:

nextGenericClass in interface Generics

Returns:

May be null.

pushTypeVariables

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

Description copied from interface: Generics

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

Specified by:

pushTypeVariables in interface Generics

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

Returns:

The number of entries that were pushed.

popTypeVariables

public void popTypeVariables(int count)

Description copied from interface: Generics

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

Specified by:

popTypeVariables in interface Generics

Parameters:

count - Must be even.

resolveTypeVariable

public Class resolveTypeVariable(TypeVariable typeVariable)

Description copied from interface: Generics

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

Specified by:

resolveTypeVariable in interface Generics

Returns:

May be null.

getGenericTypesSize

public int getGenericTypesSize()

Description copied from interface: Generics

Returns the number of generic types currently tracked

Specified by:

getGenericTypesSize in interface Generics
