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
