public static class FloatSets.EmptySet

Method Detail

remove

public boolean remove(float ok)

Description copied from interface: FloatSet

Removes an element from this set.

Note that the corresponding method of a 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 FloatSet

Collection.remove(Object)

clone

public java.lang.Object clone()

equals

public boolean equals(java.lang.Object o)

Specified by:

equals in interface java.util.Collection<java.lang.Float>

Specified by:

equals in interface java.util.Set<java.lang.Float>

Overrides:

equals in class FloatCollections.EmptyCollection

rem

@Deprecated
public boolean rem(float k)

Deprecated.

Description copied from class: AbstractFloatCollection

Removes a single instance of the specified element from this collection, if it is present (optional operation).

Note that this method should be called remove(), but the clash with the similarly named index-based method in the List interface forces us to use a distinguished name. For simplicity, the set interfaces reinstates remove().

This implementation iterates over the elements in the collection, looking for the specified element and tries to remove it.

Specified by:

rem in interface FloatCollection

Specified by:

rem in interface FloatSet

Overrides:

rem in class AbstractFloatCollection
