Detailed Description

The CharacterData interface extends Node 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 CharacterData , though Text and others do inherit the interface from it. All offsets in this interface start from 0.

Member Function Documentation

void CharacterData::appendData

(

const DOMString &

arg

)

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 DOMString specified.

Parameters

arg	The DOMString to append.

Returns

Exceptions

DOMException

NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

Definition at line 102 of file dom_text.cpp.

DOMString CharacterData::data

(

)

const

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 CharacterData node. However, implementation limits may mean that the entirety of a node's data may not fit into a single DOMString . In such cases, the user may call substringData to retrieve the data in appropriately sized pieces.

Exceptions

DOMException

DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

Definition at line 65 of file dom_text.cpp.

void CharacterData::deleteData	(	const unsigned long	offset,
		const unsigned long	count
	)

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.

Returns

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.

Definition at line 124 of file dom_text.cpp.

void CharacterData::insertData	(	const unsigned long	offset,
		const DOMString &	arg
	)

Insert a string at the specified character offset.

Parameters

offset	The character offset at which to insert.
arg	The DOMString to insert.

Returns

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.

Definition at line 113 of file dom_text.cpp.

unsigned long CharacterData::length

(

)

const

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.

Definition at line 83 of file dom_text.cpp.

CharacterData & CharacterData::operator=

(

const Node &

other

)

Definition at line 38 of file dom_text.cpp.

CharacterData & CharacterData::operator=

const CharacterData &

other

)

Definition at line 55 of file dom_text.cpp.

void CharacterData::replaceData	(	const unsigned long	offset,
		const unsigned long	count,
		const DOMString &	arg
	)

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 DOMString with which the range must be replaced.

Returns

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.

Definition at line 135 of file dom_text.cpp.

void CharacterData::setData

(

const DOMString &

str

)

see data

Exceptions

DOMException

NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

Definition at line 71 of file dom_text.cpp.

DOMString CharacterData::substringData	(	const unsigned long	offset,
		const unsigned long	count
	)

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.

DOMSTRING_SIZE_ERR: Raised if the specified range of text does not fit into a DOMString .
