Detailed Description

The DOMCharacterData interface extends DOMNode with a set of attributes and methods for accessing character data in the DOM.

For clarity this set is defined here rather than on each object that uses these attributes and methods. No DOM objects correspond directly to DOMCharacterData, though DOMText and others do inherit the interface from it. All offsets in this interface start from 0.

As explained in the DOM spec, text strings in the DOM are represented in UTF-16, i.e. as a sequence of 16-bit units. In the following, the term 16-bit units is used whenever necessary to indicate that indexing on DOMCharacterData is done in 16-bit units.

Since: DOM Level 1

Member Function Documentation

virtual void xercesc::DOMCharacterData::appendData ( const XMLCh * arg )

pure virtual

Append the string to the end of the character data of the node.

Upon success, data provides access to the concatenation of data and the XMLCh* String specified.

Parameters

arg	The `XMLCh* String` to append.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Since: DOM Level 1

virtual void xercesc::DOMCharacterData::deleteData	(	XMLSize_t	offset,
		XMLSize_t	count
	)

pure virtual

Remove a range of characters from the node.

Upon success, data and length reflect the change.

Parameters

offset	The offset from which to remove characters.
count	The number of characters to delete. If the sum of `offset` and `count` exceeds `length` then all characters from `offset` to the end of the data are deleted.

Exceptions

DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Since: DOM Level 1

virtual const XMLCh* xercesc::DOMCharacterData::getData ( ) const

pure virtual

Returns the character data of the node that implements this interface.

The DOM implementation may not put arbitrary limits on the amount of data that may be stored in a DOMCharacterData node. However, implementation limits may mean that the entirety of a node's data may not fit into a single XMLCh* String. In such cases, the user may call substringData to retrieve the data in appropriately sized pieces.

Exceptions

DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

Since: DOM Level 1

virtual XMLSize_t xercesc::DOMCharacterData::getLength ( ) const

pure virtual

Returns the number of characters that are available through data and the substringData method below.

This may have the value zero, i.e., CharacterData nodes may be empty.

Since: DOM Level 1

virtual void xercesc::DOMCharacterData::insertData	(	XMLSize_t	offset,
		const XMLCh *	arg
	)

pure virtual

Insert a string at the specified character offset.

Parameters

offset	The character offset at which to insert.
arg	The `XMLCh* String` to insert.

Exceptions

DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in data.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Since: DOM Level 1

virtual void xercesc::DOMCharacterData::replaceData	(	XMLSize_t	offset,
		XMLSize_t	count,
		const XMLCh *	arg
	)

pure virtual

Replace the characters starting at the specified character offset with the specified string.

Parameters

offset	The offset from which to start replacing.
count	The number of characters to replace. If the sum of `offset` and `count` exceeds `length` , then all characters to the end of the data are replaced (i.e., the effect is the same as a `remove` method call with the same range, followed by an `append` method invocation).
arg	The `XMLCh* String` with which the range must be replaced.

Exceptions

DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Since: DOM Level 1

virtual void xercesc::DOMCharacterData::setData ( const XMLCh * data )

pure virtual

Sets the character data of the node that implements this interface.

Parameters

data	The `XMLCh* String` to set.

Since: DOM Level 1

virtual const XMLCh* xercesc::DOMCharacterData::substringData	(	XMLSize_t	offset,
		XMLSize_t	count
	)		const

pure virtual

Extracts a range of data from the node.

Parameters

offset	Start offset of substring to extract.
count	The number of characters to extract.

Returns: The specified substring. If the sum of offset and count exceeds the length, then all characters to the end of the data are returned.

Exceptions

DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of characters in data, or if the specified count is negative.
