Method Detail

channelIndex

int channelIndex()

Specified by:

channelIndex in interface StorageHashChannelPart

reset

void reset()

Description copied from interface: StorageChannelResetablePart

Closes all resources (files, locks, etc.). Clears all variable length items (cache, registry, etc.). Resets internal state to initial values. For itself and all its parts (entity cache, file manager, etc.). Basically a "back to just being born" action.

Specified by:

reset in interface StorageChannelResetablePart
