java.lang.Object | ||
android.os.ConditionVariable |
Class that implements the condition variable locking paradigm.
This differs from the built-in java.lang.Object wait() and notify() in that this class contains the condition to wait on itself. That means open(), close() and block() are sticky. If open() is called before block(), block() will not block, and instead return immediately.
This class uses itself is at the object to wait on, so if you wait() or notify() on a ConditionVariable, the results are undefined.
ConditionVariable() | ||||||
Create the ConditionVariable in the default closed state. | ||||||
ConditionVariable(boolean state) | ||||||
Create the ConditionVariable with the given state. |
boolean | block(long timeout) | |||||
Block the current thread until the condition is opened or until timeout milliseconds have passed. | ||||||
void | block() | |||||
Block the current thread until the condition is opened. | ||||||
void | close() | |||||
Reset the condition to the closed state. | ||||||
void | open() | |||||
Open the condition, and release all threads that are blocked. |
Pass true for opened and false for closed.
If the condition is already opened, return immediately.
timeout | the minimum time to wait in milliseconds. |
---|
If the condition is already opened, return immediately.
Any threads that call block() will block until someone calls open.
Any threads that later approach block() will not block unless close() is called.
