Method Detail

remove

public boolean remove(char ok)
Description copied from interface: CharSet
Removes an element from this set.

Note that the corresponding method of the type-specific collection is rem(). This unfortunate situation is caused by the clash with the similarly named index-based method in the List interface.

Specified by:
remove in interface CharSet

clone
