rem

@Deprecated
public boolean rem(char k)

Deprecated.

Description copied from interface: CharSet

Removes an element from this set.

This method is inherited from the type-specific collection this type-specific set is based on, but it should not used as this interface reinstates remove() as removal method.

Specified by:

rem in interface CharSet

Overrides:

rem in class it.unimi.dsi.fastutil.chars.AbstractCharCollection
