Method Details

getLocalId

public static CounterId getLocalId()

fromInt

public static CounterId fromInt(int n)

Pack an int in a valid CounterId so that the resulting ids respects the numerical ordering. Used for creating handcrafted but easy to understand contexts in unit tests (see CounterContextTest). Also used to generate a special ID for special-case update contexts (see CounterContext.createUpdate()).
