Detailed Description

A map in the XDM data model. A map is a list of zero or more entries, each of which is a pair comprising a key (which is an atomic value) and a value (which is an arbitrary value). The map itself is an XDM item.

An XdmMap is immutable.

◆ XdmMap() [3/4]

XdmMap::XdmMap ( jobject obj )

XdmMap constructor which is a wrapper object from the Java XdmMap object - internal use.

Parameters

obj	- The internal Java object for the XdmMap is wrapped here in the C++ XdmMap

◆ XdmMap() [4/4]

XdmMap::XdmMap ( std::map< XdmAtomicValue *, XdmValue * > map )

Create an XdmMap supplying the entries in the form of a std::map, where the keys and values in the std::map are XDM values.

Parameters

map	- a std::map whose entries are the (key, value) pairs

Member Function Documentation

◆ containsKey()

bool XdmMap::containsKey ( XdmAtomicValue * key )

Returns true if this map contains a mapping for the specified key.

More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)

Parameters

key	key whose presence in this map is to be tested

Returns: true if this map contains a mapping for the specified key

◆ get() [1/5]

XdmValue * XdmMap::get ( const char * key )

Returns the value to which the specified string-valued key is mapped, or NULL if this map contains no mapping for the key.

This is a convenience method to save the trouble of converting the String to an XdmAtomicValue.

Parameters

key	the key whose associated value is to be returned. This is treated as an instance of `xs:string` (which will also match entries whose key is `xs:untypedAtomic` or `xs:anyURI`)

Returns: the value to which the specified key is mapped, or NULL if this map contains no mapping for the key

◆ get() [2/5]

XdmValue * XdmMap::get ( double key )

Returns the value to which the specified double-valued key is mapped, or NULL if this map contains no mapping for the key. This is a convenience method to save the trouble of converting the double to an XdmAtomicValue.

Parameters

key	the key whose associated value is to be returned. This is treated as an instance of `xs:double` (which will also match entries whose key belongs to another numeric type)

Returns: the value to which the specified key is mapped, or NULL if this map contains no mapping for the key

◆ get() [3/5]

XdmValue * XdmMap::get ( int key )

Returns the value to which the specified integer-valued key is mapped or NULL if this map contains no mapping for the key.

This is a convenience method to save the trouble of converting the integer to an XdmAtomicValue.

Parameters

key	the key whose associated value is to be returned. This is treated as an instance of `xs:integer` (which will also match entries whose key belongs to another numeric type)

Returns: the value to which the specified key is mapped, or NULL if this map contains no mapping for the key

◆ get() [4/5]

XdmValue * XdmMap::get ( long key )

Returns the value to which the specified integer-valued key is mapped or NULL if this map contains no mapping for the key. This is a convenience method to save the trouble of converting the integer to an XdmAtomicValue.

Parameters

key	the key whose associated value is to be returned. This is treated as an instance of `xs:integer` (which will also match entries whose key belongs to another numeric type)

Returns: the value to which the specified key is mapped, or NULL if this map contains no mapping for the key

◆ get() [5/5]

XdmValue * XdmMap::get ( XdmAtomicValue * key )

Returns the value to which the specified key is mapped, or NULL if this map contains no mapping for the key.

Parameters

key	the key whose associated value is to be returned.

Returns: the value to which the specified key is mapped, or NULL if this map contains no mapping for the key

Remarks: if null is returned check getException method on the SaxonProcessor object for errors

◆ isEmpty()

bool XdmMap::isEmpty ( )

Returns true if this map contains no key-value mappings.

Returns: true if this map contains no key-value mappings

◆ isFunction()

bool XdmMap::isFunction ( )

inlinevirtual

Determine whether the item is a function or some other type of item.

Returns: true if the item is a Xdm function item, false if it is an atomic value or a function (including maps and arrays)

Reimplemented from XdmFunctionItem.

◆ isMap()

bool XdmMap::isMap ( )

inlinevirtual

Determine whether the item is a map or some other type of item.

Returns: true if the item is a Xdm map item, false if it is some other type

Reimplemented from XdmItem.

◆ keys()

XdmAtomicValue ** XdmMap::keys ( )

Get the keys present in the map in the form of an unordered pointer array of XdmAtomicValue.

Returns: an unordered pointer array of the keys present in this map, in arbitrary order.

◆ keySet()

std::set< XdmAtomicValue * > XdmMap::keySet ( )

Get the keys present in the map in the form of an unordered std::set.

Returns: an unordered std::set of the keys present in this map, in arbitrary order.

◆ mapSize()

int XdmMap::mapSize ( )

Get the number of entries in the map.

Returns: the number of entries in the map. (Note that the size() method returns 1 (one), because an XDM map is an item.)

◆ put()

XdmMap * XdmMap::put	(	XdmAtomicValue *	key,
		XdmValue *	value
	)

Create a new map containing an additional (key, value) pair.

If there is an existing entry with the same key, it is removed

Returns: a new map containing the additional entry. The original map is unchanged.

◆ remove()

XdmMap * XdmMap::remove ( XdmAtomicValue * key )

Create a new map in which the entry for a given key has been removed.

If there is no entry with the same key, the new map has the same content as the old (it may or may not be the same Java object)

Parameters

key	- The key to be removed given as an XdmAtomicValue

Returns: a map without the specified entry. The original map is unchanged.

◆ toString()

const char * XdmMap::toString ( )

virtual

The toString() method returns a simple XML serialization of the node with defaulted serialization parameters.

In the case of an element node, the result will be a well-formed XML document serialized as defined in the W3C XSLT/XQuery serialization specification, using options method="xml", indent="yes", omit-xml-declaration="yes".

In the case of a document node, the result will be a well-formed XML document provided that the document node contains exactly one element child, and no text node children. In other cases it will be a well-formed external general parsed entity.

In the case of an attribute node, the output is a string in the form name="value". The name will use the original namespace prefix.

In the case of a namespace node, the output is a string in the form of a namespace declaration, that is xmlns="uri" or xmlns:pre="uri".

Other nodes, such as text nodes, comments, and processing instructions, are represented as they would appear in lexical XML. Note: this means that in the case of text nodes, special characters such as & and < are output in escaped form. To get the unescaped string value of a text node, use getStringValue() instead.

Returns: a simple XML serialization of the node. Under error conditions the method may return an error message which will always begin with the label "Error: ".

Reimplemented from XdmItem.

◆ values()

XdmValue ** XdmMap::values ( )

Returns a pointer array containing the values found in this map, that is, the value parts of the key-value pairs.

Returns: a pointer array containing the values found in this map. The result may contain duplicates, and the ordering of the collection is unpredictable.

◆ valuesAsList()

std::list< XdmValue * > XdmMap::valuesAsList ( )

Returns a std::list containing the values found in this map, that is, the value parts of the key-value pairs.

Returns: a std::list containing the values found in this map. The result may contain duplicates, and the ordering of the collection is unpredictable.
