If this is a parameterized type, returns the generic type this type parameterizes. Otherwise, returns null.

Description copied from interface: IType

True if this type cannot be extended.

Specified by:

public boolean isInterface()

Description copied from interface: IType

Returns true if this type is an interface.

isParameterizedType

public boolean isParameterizedType()

Description copied from interface: IType

Returns true if this ia a Parameterized Type.

Note a Parameterzied Type is not the same as a Generic Type. The difference is that a Parameterized Type is a concrete version of a Generic Type. For instance, the class ArrayList is a Generic Type, while the class ArrayList is a Parameterized Type of the the Generic Type ArrayList.

public IType getParameterizedType(IType... ofType)

Description copied from interface: IType

Assuming this intrinsic type is a Generic type, return the parameterized type associated with the given list of type parameters. If the type has not been created yet, creates the parameterized type. Successive calls to this method having identical parameter types must return the identical parameterized type.

Specified by:

getParameterizedType in interface IType

Parameters:

ofType - The type parameters.

Returns:

The concrete type associated with the type parameters.

True if this type represents a primitive type e.g., Java int, char, etc.

Specified by:

isMutable

public boolean isMutable()

Description copied from interface: IType

Are intances of this type mutable? Note sometimes it's difficult to determine. For instance, java classes don't contain any information about mutability.
