Method Summary

Modifier and TypeMethod and Description
protected FastCopyHashMap<String, Object>
childValue(final FastCopyHashMap<String, Object>
the parent thread's value
parentValue)

Overrides java.lang.InheritableThreadLocal.childValue.

Computes the child's initial value for this inheritable thread-local variable as a function of the parent's value at the time the child thread is created.

protected FastCopyHashMap<String, Object> childValue(final FastCopyHashMap<String, Object> parentValue)

Overrides java.lang.InheritableThreadLocal.childValue.

Doc from java.lang.InheritableThreadLocal.childValue.

Computes the child's initial value for this inheritable thread-local variable as a function of the parent's value at the time the child thread is created. This method is called from within the parent thread before the child is started.

This method merely returns its input argument, and should be overridden if a different behavior is desired.

Parameters
parentValue:FastCopyHashMap<String, Object>

the parent thread's value

Returns:FastCopyHashMap<String, Object>

the child thread's initial value

Annotations

protected FastCopyHashMap<String, Object> initialValue()

Overrides java.lang.ThreadLocal.initialValue.

Doc from java.lang.ThreadLocal.initialValue.

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

Returns:FastCopyHashMap<String, Object>

the initial value for this thread-local
