protected static final int STATE_CALLID_PARSED

callID

protected long callID

See "callidState" for explanations.

contextState

protected int contextState

In case "isContextPresent" is set to "true", defines the state of context construction process in the similar way as it is done for "tableState".

STATE_CONTEXT_INACTIVE

protected static final int STATE_CONTEXT_INACTIVE

STATE_CONTEXT_ACTIVE

protected static final int STATE_CONTEXT_ACTIVE

STATE_CONTEXT_COMPLETE

protected static final int STATE_CONTEXT_COMPLETE
