Detailed Description

The base interface of all collections managed by Coherence.

A collection is a group of objects also known as elements. The following behaviors of a collection are implementation dependent:

Unless otherwise stated, collections are assumed to not support any of the above.

Member Function Documentation

virtual size32_t size (  )  const [pure virtual]

Return the number of elements in this collection.

Returns:
the number of elements in this collection

Implemented in AbstractCollection, CircularArrayList, DeltaSet, LinkedList, LiteSet, ReadOnlyMultiList, SafeHashMap::EntrySet, SubList, SubSet, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual bool isEmpty (  )  const [pure virtual]

Determine whether this collection contains any elements.

Returns:
true if this collection has no elements

Implemented in AbstractCollection, LiteSet, SubSet, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual bool contains ( Object::View  v  )  const [pure virtual]

Determine if this collection contains the specified element.

Parameters:
v  the element to test for containment
Returns:
true iff this collection contains the given element

Implemented in AbstractCollection, ConverterCollections::ConverterCollection, ConverterCollections::ConverterSet, DeltaSet, LiteSet, MapKeySet, MapValuesCollection, ReadOnlyMultiList, SafeHashMap::EntrySet, SubSet, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual bool containsAll ( Collection::View  vCol  )  const [pure virtual]

Determine if this collection contains all elements from the supplied collection.

Parameters:
vCol  the collection of elements to test for containment
Returns:
true iff this collection contains all elements from the supplied collection
Exceptions:
coherence::lang::NullPointerException  if the specified collection is NULL
See also:
contains()

Implemented in AbstractCollection, ConverterCollections::ConverterCollection, ConverterCollections::ConverterSet, LiteSet, MapKeySet, MapValuesCollection, SubSet, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual Iterator::Handle iterator (  )  const [pure virtual]

Return an Iterator over this collection.

Returns:
an Iterator over this collection

Implemented in CircularArrayList, ConverterCollections::ConverterCollection, ConverterCollections::ConverterSet, DeltaSet, LinkedList, LiteSet, MappedSet, ReadOnlyMultiList, SafeHashMap::EntrySet, SubList, SubSet, TypedCollections::TypedCollection, TypedCollections::TypedSet, TypedCollections::TypedList, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual Muterator::Handle iterator (  )  [pure virtual]

Return an Iterator over this collection.

Returns:
an Iterator over this collection

Implemented in CircularArrayList, ConverterCollections::ConverterCollection, ConverterCollections::ConverterSet, DeltaSet, LinkedList, LiteSet, MappedSet, ReadOnlyMultiList, SafeHashMap::EntrySet, SubList, SubSet, TypedCollections::TypedCollection, TypedCollections::TypedSet, TypedCollections::TypedList, WrapperCollections::AbstractWrapperCollection, WrapperCollections::AbstractWrapperSet, and WrapperCollections::AbstractWrapperList.

virtual ObjectArray::Handle toArray ( ObjectArray::Handle  hao = NULL  )  const [pure virtual]

Return the contents of this collection as an ObjectArray.

If the collection fits in the specified array, it is returned, otherwise, a new array is allocated that is the size of this collection.

If this collection fits in the array with aditional room then the element in the array immediately following the end of the collection is set to NULL. This can be useful in determining the length of this collection if the caller knows that the collection does not contain any NULL elements.

Parameters:
hao  an array in which to store the collection's contents
Returns:
a ObjectArray containing all the elements of the collection in the same order as returned by the collection's Iterator
See also:
Iterator
