increment

public void increment(int level)

Increment a specific level of the counter. If this is not the deepest level of the counter the counter will lose the deeper levels.

Parameters:

level -

down

public void down()

Add a new level to the counter hierarchy starting at 1.

down

public void down(int i)

Discard a level in the hierarchy.

before

public boolean before(java.lang.String input)

Is the current value before (or equal to) this input?

after

public boolean after(java.lang.String input)

IS the current value after (or equal to) this input?

compare

public int compare(java.lang.String input)

Does the given string come before or after the current value. The following sequence is increasing: 1 1.1 1.2 1.2.1 1.2.2 1.3. Returns -1 if the current value comes before the input string, 0 if they are equal or 1 if the current value comes after the input.
