Method Detail

get

public T get()

Description copied from interface: ContextLocal

Returns the value in the current context’s copy of this context-local variable. If the variable has no value for the current context, it is first initialized to the value returned by an invocation of the ContextLocal.initialValue() method.

Specified by:

get in interface ContextLocal<T>

Returns:

the current thread’s value of this thread-local

set

public void set(T value)

Description copied from interface: ContextLocal

Sets the current context’s copy of this context-local variable to the specified value. Most subclasses will have no need to override this method, relying solely on the ContextLocal.initialValue() method to set the values of context-locals.

Specified by:

set in interface ContextLocal<T>

Parameters:

value - the value to be stored in the current context’s copy of this context-local.

remove

public void remove()

Description copied from interface: ContextLocal

Removes the current context’s value for this context-local variable. If this context-local variable is subsequently read by the current thread, its value will be reinitialized by invoking its ContextLocal.initialValue() method, unless its value is set by the current context in the interim. This may result in multiple invocations of the initialValue method in the current context.

Specified by:

remove in interface ContextLocal<T>
