Originally written by Doug Lea and released into the public domain. Thanks for the assistance and support of Sun Microsystems Labs, Agorics Inc, Loral, and everyone contributing, testing, and using this code.

History:

class MapCollection(K, T) : Collection!(T), Map!(K, T) ¶#

MapCollection extends Collection to provide default implementations of some Map operations.

Author:

Doug Lea @version 0.93

For an introduction to this package see Overview .

this() [protected] ¶#

Initialize at version 0, an empty count, and null screener

this(Predicate screener) [protected] ¶#

Initialize at version 0, an empty count, and supplied screener

bool allowsKey(K key) [public, final] ¶#

Implements tango.util.collection.Map.allowsKey. Default key-screen. Just checks for null.

See Also:

tango.util.collection.Map.allowsKey

void checkKey(K key) [protected, final] ¶#

Principal method to throw a IllegalElementException for keys

void opIndexAssign(T element, K key) [public, final] ¶#

Implements tango.util.collection.impl.MapCollection.MapCollection.opIndexAssign Just calls add(key, element).

tango.util.collection.impl.MapCollection.MapCollection.add

bool matches(View!(T) other) [public, override] ¶#

Implements tango.util.collection.impl.Collection.Collection.matches Time complexity: O(n). Default implementation. Fairly sleazy approach. (Defensible only when you remember that it is just a default impl.) It tries to cast to one of the known collection interface types and then applies the corresponding comparison rules. This suffices for all currently supported collection types, but must be overridden if you define new Collection subinterfaces and/or implementations.

void removeAll(Iterator!(T) e) [public] ¶#

Implements tango.util.collection.impl.Collection.Collection.removeAll

See Also:

tango.util.collection.impl.Collection.Collection.removeAll

Has to be here rather than in the superclass to satisfy D interface idioms

void remove(Iterator!(T) e) [public] ¶#

Implements tango.util.collection.impl.Collection.Collection.removeElements

See Also:

tango.util.collection.impl.Collection.Collection.removeElements
