Method Detail

contains

public boolean contains(java.lang.Object target)

Specified by:

contains in interface java.util.Collection<E>

Specified by:

contains in interface java.util.Set<E>

Specified by:

contains in class ImmutableCollection<E>

size

public int size()

Specified by:

size in interface java.util.Collection<E>

Specified by:

size in interface java.util.Set<E>

Specified by:

size in class java.util.AbstractCollection<E>

Description copied from class: ImmutableCollection

Returns an unmodifiable iterator across the elements in this collection.

Specified by:

iterator in interface java.util.Collection<E>

Specified by:

iterator in interface java.lang.Iterable<E>

Specified by:

iterator in interface java.util.Set<E>

Specified by:

iterator in class ImmutableSet<E>

spliterator

public java.util.Spliterator<E> spliterator()

Specified by:

spliterator in interface java.util.Collection<E>

Specified by:

spliterator in interface java.lang.Iterable<E>

Specified by:

spliterator in interface java.util.Set<E>

Overrides:

spliterator in class ImmutableCollection<E>

internalArray

java.lang.Object[] internalArray()

Description copied from class: ImmutableCollection

If this collection is backed by an array of its elements in insertion order, returns it.

Overrides:

internalArray in class ImmutableCollection<E>

internalArrayStart

int internalArrayStart()

Description copied from class: ImmutableCollection

If this collection is backed by an array of its elements in insertion order, returns the offset where this collection's elements start.

Overrides:

internalArrayStart in class ImmutableCollection<E>

internalArrayEnd

int internalArrayEnd()

Description copied from class: ImmutableCollection

If this collection is backed by an array of its elements in insertion order, returns the offset where this collection's elements end.

Overrides:

createAsList

ImmutableList<E> createAsList()

Overrides:

isPartialView

boolean isPartialView()

Description copied from class: ImmutableCollection

Returns true if this immutable collection's implementation contains references to user-created objects that aren't accessible via this collection's methods. This is generally used to determine whether copyOf implementations should make an explicit copy to avoid memory leaks.

Specified by:

isPartialView in class ImmutableCollection<E>

isHashCodeFast

boolean isHashCodeFast()

Description copied from class: ImmutableSet

Returns true if the hashCode() method runs quickly.

Overrides:

isHashCodeFast in class ImmutableSet<E>
