clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

rem

@Deprecated
public boolean rem(double k)

Deprecated.

Description copied from interface: DoubleSet

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.

rem in interface it.unimi.dsi.fastutil.doubles.DoubleCollection

Specified by:

rem in interface DoubleSet

Overrides:

rem in class it.unimi.dsi.fastutil.doubles.AbstractDoubleCollection
