getState

public static StatsCollectionState getState()

Returns the current StatsCollectionState.

Once getState() is called, subsequent calls to setState(StatsCollectionState) will throw an IllegalStateException.

Returns:

the current StatsCollectionState.

Since:

setState

@Deprecated
public static void setState(StatsCollectionState state)

Deprecated.

This method is deprecated because other libraries could cache the result of getState(), use a stale value, and behave incorrectly. It is only safe to call early in initialization. This method throws IllegalStateException after getState() has been called, in order to limit changes to the result of getState().

Sets the current StatsCollectionState.

When no implementation is available, setState does not change the state.

If state is set to StatsCollectionState.DISABLED, all stats that are previously recorded will be cleared.

Parameters:

state - the new StatsCollectionState.

Throws:

java.lang.IllegalStateException - if getState() was previously called.

0.8
