Modifier and Type	Method and Description
T	cast(Object object) Cast the given object to the underlying type of this token.
boolean	equals(Object obj) Generic equal implementation for type tokens that evaluates to equal, if the given object is an instance of the direct supertype of the questioned instance, plus having equal generic types.
Type	getType() Gets the token's type.
boolean	isInstance(Object object) Test the given object to be an instance of the underlying (raw) type of this token.

public TypeToken()

Method Detail

getType

public final Type getType()

Gets the token's type.

Returns:

The type of this token.

Since:

4.2.405

cast

public T cast(Object object)

Cast the given object to the underlying type of this token. Will throw ClassCastException, if the given object is not assignable to this token's raw type, but will not check for the generic type.

Parameters:

object - The object to be cast.

Returns:

The cast instance.

Since:

4.2.405

isInstance

public boolean isInstance(Object object)

Test the given object to be an instance of the underlying (raw) type of this token.

Parameters:

object - The object to be tested.

Returns:

true, iff the object is a matching instance.

Since:

4.2.405

equals

public final boolean equals(Object obj)

Generic equal implementation for type tokens that evaluates to equal, if the given object is an instance of the direct supertype of the questioned instance, plus having equal generic types.

The implementation is optimzed to return early where the generic type of the compared type token differs. If they are the same then a relativ costly check for the equality of the superclassis performed.

Overrides:

equals in class Object

Parameters:

obj - The object given for comparison.

Returns:

true, iff both instances have the same supertype and equal generic types.

4.2.405
