public class GenericType
extends ReifiedType

XXXX: Currently, in case of arrays getActualTypeArgument(0) returns something similar to what Class.getComponentType() does for arrays. I don't think this is quite right since getActualTypeArgument() should return the given parameterized type not the component type. Need to check this behavior with the spec.

getActualTypeArgument

public ReifiedType getActualTypeArgument(int i)

Description copied from class: ReifiedType

Return a type parameter for this type. The type parameter refers to a parameter in a generic type declaration given by the zero-based index i. For example, in the following example:

 Map<String, ? extends Metadata>
 

type parameter 0 is String, and type parameter 1 is Metadata.

This implementation returns a Reified Type that has Object as class. Any object is assignable to Object and therefore no conversion is then necessary. This is compatible with versions of Java language prior to Java 5. This method should be overridden by a subclass that provides access to the generic type parameter information for Java 5 and later.

Overrides:

getActualTypeArgument in class ReifiedType

Parameters:

i - The zero-based index of the requested type parameter.

Returns:

The ReifiedType for the generic type parameter at the specified index.

size

public int size()

Description copied from class: ReifiedType

Return the number of type parameters for this type.

This implementation returns 0. This method should be overridden by a subclass that provides access to the generic type parameter information for Java 5 and later.

Overrides:

size in class ReifiedType

Returns:

The number of type parameters for this type.

toString

public String toString()

Overrides:

toString in class Object

equals

public boolean equals(Object object)

Overrides:

equals in class Object
