MapItem	Interface supported by different implementations of an XDM map item

Class Summary

Class	Description
HashTrieMap	An immutable map.
KeyValuePair	A key and a corresponding value to be held in a Map.
MapContains	Implementation of the XPath 3.0 function map:contains(Map, key) => boolean
MapCreate	This is a variant of the map:new() or map:merge() function which differs in that duplicate keys are considered an error.
MapEntry	Implementation of the extension function map:entry(key, value) => Map
MapForEach	Implementation of the extension function map:for-each(Map, Function) => item()*
MapGet	Implementation of the XPath 3.0 function map:get(Map, key) => value
MapKeys	Implementation of the extension function map:keys(Map) => atomicValue*
MapMerge	Implementation of the extension function map:merge() => Map This function replaces map:new (May 2014) which is retained in Saxon for the time being.
MapNew	Implementation of the extension function map:new() => Map Note this function has been dropped from the spec (May 2014) but is retained in Saxon for the time being.
MapPut	Implementation of the extension function map:put() => Map This function has been added to the spec in May 2014
MapRemove	Implementation of the XPath 3.0 function map:remove(Map, key) => value
MapSize	Implementation of the extension function map:entry(key, value) => Map
MapType	An instance of this class represents a specific map item type, for example function(xs:int) as xs:boolean
RangeKey	This class implements an XPath map item as a view of an XSLT key index.

Package com.saxonica.functions.map Description

This package implements maps, a Saxon extension to the XSLT and XQuery specification that provides a dictionary-like data structure.

Maps are immutable, so that adding a new entry to a map creates a new map.

The entries in a map are (Key, Value) pairs. The key is always an atomic value; the value may be any XPath sequence.

There are functions (each supported by its own implementation class) to create a new map, to add an entry to a map, to get an entry from a map, and to list all the keys that are present in a map.
