Type checked get method

Type Parameters:

T - Return type

Parameters:

key - Key

restriction - restriction class

Returns:

Object that is guaranteed to be of class restriction or null

getGenerics

public <T> T getGenerics(K key,
                         Class<?> restriction)

(Largely) type checked get method for use with generic types

Type Parameters:

T - Return type

Parameters:

key - Key

restriction - restriction class

Returns:

Object that is guaranteed to be of class restriction or null

get

@Deprecated
public Object get(Object key)

Deprecated. use get(Object, Class) or getGenerics(Object, Class) instead, for type safety!

Depreciate the use of the untyped get method.
