Detailed Description

The class RWXmlObjectOutputStreamImp serializes one or more objects as an XML-formatted data stream and passes the stream to a supplied RWDataOutputStream.

The XML Streams Module integrates with the general Rogue Wave streams architecture defined by the streams and serialization packages of the Advanced Tools Module of SourcePro Core. This architecture allows an XML stream to be written out and read in using a wide variety of streaming configurations. For more information specific to the XML Streams Module, see the XML Streams Module User's Guide. For information on the general architecture, see the Advanced Tools Module User's Guide.

RWXmlObjectOutputStreamImp is the body class of a handle-body pattern. The corresponding handle class is RWObjectOutputStream.

The syntax of the XML formatting generated by this class is defined by the XML schema xmlstreams.xsd. This schema is located in buildspace\rw\xmlstreams.

Example: // Create a strstream as the output stream to receive

// the XML-formatted object data

ostrstream s;

// Create an XML data stream using the strstream

RWObjectOutputStream out = RWXmlObjectOutputStreamImp::make(s);

// Write integer value `1' to XML data stream

s << 1;

Constructor & Destructor Documentation

RWXmlObjectOutputStreamImp::RWXmlObjectOutputStreamImp	(	std::ostream &	ostr,
		const RWCString &	rootElementType,
		bool	escape
	)

inlineprotected

Used by the make() function and potentially by derived classes to initialize an output stream to be used as the sink for the XML-formatted object serialization data. Use this constructor if the required output stream is a standard library ostream and pass a reference to that stream as the ostr parameter.

The parameter rootElementType must be one of the following:

nestedObjectTag, if serializing an object by value
objectTag, if serializing an object by pointer
sequenceTag, if serializing a sequential collection such as RWTPtrOrderedVector
mapTag, if serializing a mapping collection such as RWTPtrHashMap
primitiveTag, if serializing a built-in type such as int

The value passed indicates the root element of the generated document.

The parameter escape sets whether to escape XML reserved characters in the data being serialized. By setting this parameter to true, reserved characters in char and string values are escaped, allowing the data to include embedded XML.

The reserved characters are:

< > & " '

You get slightly better performance if the escape parameter is set to false, but before doing so be certain that your data does not contain reserved characters.

		std::ios *&	formatter,

You get slightly better performance if the escape parameter is set to false, but before doing so be certain that your data does not contain reserved characters.

This constructor also takes a pointer reference to an std::ios formatting object. An empty formatting object pointer is created before the XML stream is created and is passed to this constructor through the make() function. This constructor, in creating the underlying character stream for the XML stream, creates a formatting object for the stream and places the address of that object in the pointer reference. The calling application can then use this formatting object to manipulate data formats in the XML stream. See the corresponding make() function description for an example.

Member Function Documentation

virtual void RWXmlObjectOutputStreamImp::closeOuterContext ( bool writeContext )

protectedvirtual

Really closes an open context. This function is called when the number of closeContext() calls matches the number of openContext() calls.

string	A pointer to the narrow string's first character.
count	The number of narrow character(s) to be written to the stream.

ustring	A pointer to the string's first unicode character.
count	The number of unicode character(s) to be written to the stream.

wstring	A pointer to the string's first wide character.
count	The number of wide character(s) to be written to the stream.

count	Contains the number of items in the association.
keyType	Contains the type of key in the association.
valueType	Contains the type of value in the association.
typeInfo	Contains the type of the association (collection) itself.

count	Contains the number of items in the collection.
elementType	Contains the type of element in the collection.
typeInfo	Contains the type of the collection itself.

memberName	Identifies the name of the member.
memberType	Identifies the type of the member.
