Constructor Detail

AsmClassAccess

protected AsmClassAccess(Class<C> clazz)

Constructor, intended for use by generated subclasses

Parameters:

clazz - The Class to be accessed

Method Detail

isNonStaticMemberClass

public boolean isNonStaticMemberClass()

Indicates if the class being accessed is a non-static member class

Returns:

True if the class is a non-static member class

get

public static <C> AsmClassAccess<C> get(Class<C> clazz)

Get a new instance that can access the given Class. If the ClassAccess for this class has not been obtained before, then the specific AsmClassAccess is created by generating a specialised subclass of this class and returning it.

Type Parameters:

C - The type of class

Parameters:

clazz - Class to be accessed

Returns:

New AsmClassAccess instance

newInstance

public abstract C newInstance()

Description copied from interface: ClassAccess

Create a new, uninitialised instance of the given class (if supported). Depending on strategy, this may or may not initialise instance fields, and may or may not invoke constructors.

Specified by:

newInstance in interface ClassAccess<C>

Returns:

The new instance of the type, C.
