asListback to summary
public ImmutableList<E> asList()

Overrides com.google.common.collect.ImmutableCollection.asList.

Doc from com.google.common.collect.ImmutableCollection.asList.

Returns an ImmutableList containing the same elements, in the same order, as this collection.

Performance note: in most cases this method can return quickly without actually copying anything. The exact circumstances under which the copy is performed are undefined and subject to change.

public boolean contains(Object target)

Implements abstract com.google.common.collect.ImmutableCollection.contains.

Implements java.util.Set.contains, java.util.Collection.contains.

Doc from java.util.Set.contains.

Returns true if this set contains the specified element. More formally, returns true if and only if this set contains an element e such that Objects.equals(o, e).

Parameters
target:Object

element whose presence in this set is to be tested

Returns:boolean

true if this set contains the specified element

hashCodeback to summary
public final int hashCode()

Overrides com.google.common.collect.ImmutableSet.hashCode.

Implements java.util.Set.hashCode, java.util.Collection.hashCode.

Doc from java.util.Set.hashCode.

Returns the hash code value for this set. The hash code of a set is defined to be the sum of the hash codes of the elements in the set, where the hash code of a null element is defined to be zero. This ensures that s1.equals(s2) implies that s1.hashCode()==s2.hashCode() for any two sets s1 and s2, as required by the general contract of Object#hashCode.

Returns:int

the hash code value for this set

pack-priv boolean isPartialView()

Implements abstract com.google.common.collect.ImmutableCollection.isPartialView.

Doc from com.google.common.collect.ImmutableCollection.isPartialView.

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.

Annotations

public UnmodifiableIterator<E> iterator()

Implements abstract com.google.common.collect.ImmutableSet.iterator.

Implements java.util.Set.iterator, java.util.Collection.iterator.

Doc from java.util.Set.iterator.

Returns an iterator over the elements in this set. The elements are returned in no particular order (unless this set is an instance of some class that provides a guarantee).

Returns:UnmodifiableIterator<E>

an iterator over the elements in this set

@Override
sizeback to summary
public int size()

Implements abstract java.util.AbstractCollection.size.

Implements java.util.Set.size, java.util.Collection.size.

Doc from java.util.Set.size.

Returns the number of elements in this set (its cardinality). If this set contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

Returns:int

the number of elements in this set (its cardinality)

Annotations
@Override
toStringback to summary
public String toString()

Overrides java.util.AbstractCollection.toString.

Doc from java.util.AbstractCollection.toString.

Returns a string representation of this collection. The string representation consists of a list of the collection's elements in the order they are returned by its iterator, enclosed in square brackets ("[]"). Adjacent elements are separated by the characters ", " (comma and space). Elements are converted to strings as by String#valueOf(Object).

Returns:String

a string representation of this collection
