Method Detail

initialValue

public T initialValue()

Description copied from interface: ContextLocal

Returns the current context’s “initial value” for this context-local variable. This method will be invoked the first time a context accesses the variable with the ContextLocal.get() method, unless the context previously invoked the ContextLocal.set(T) method, in which case the initialValue method will not be invoked for the context. Normally, this method is invoked at most once per context, but it may be invoked again in case of subsequent invocations of ContextLocal.remove() followed by ContextLocal.get().

Specified by:

initialValue in interface ContextLocal<T>

Specified by:

initialValue in class ContextLocal.InitialValueProvider<T>

Returns:
