                         String nodeValue)

Method Detail

checkLoaded

protected final void checkLoaded()

Overrides:

checkLoaded in class NodeImpl

setNodeValue

public final void setNodeValue(String nodeValue)
                        throws org.w3c.dom.DOMException

Description copied from class: NodeImpl

The value of this node, depending on its type; see the table above. When it is defined to be null , setting it has no effect.

Specified by:

setNodeValue in interface org.w3c.dom.Node

Overrides:

setNodeValue in class NodeImpl

Following copied from class: org.apache.xindice.xml.dom.NodeImpl

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

org.w3c.dom.DOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

substringData

public final String substringData(int offset,
                                  int count)
                           throws org.w3c.dom.DOMException

Extracts a range of data from the node.

Specified by:

substringData in interface org.w3c.dom.CharacterData

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.

Throws:

org.w3c.dom.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.

getData

public final String getData()
                     throws org.w3c.dom.DOMException

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.

Specified by:

getData in interface org.w3c.dom.CharacterData

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.

org.w3c.dom.DOMException - DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

setData

public final void setData(String data)
                   throws org.w3c.dom.DOMException

Specified by:

setData in interface org.w3c.dom.CharacterData

insertData

public final void insertData(int offset,
                             String arg)
                      throws org.w3c.dom.DOMException

Insert a string at the specified character offset.

Specified by:

insertData in interface org.w3c.dom.CharacterData

Parameters:

offset - The character offset at which to insert.

arg - The DOMString to insert.

Throws:

org.w3c.dom.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.

getLength

public final int getLength()

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.

Specified by:

getLength in interface org.w3c.dom.CharacterData

replaceData

public final void replaceData(int offset,
                              int count,
                              String arg)
                       throws org.w3c.dom.DOMException

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

Specified by:

replaceData in interface org.w3c.dom.CharacterData

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.

Throws:

org.w3c.dom.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.

appendData

public final void appendData(String arg)
                      throws org.w3c.dom.DOMException

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.

Specified by:

appendData in interface org.w3c.dom.CharacterData

Parameters:

arg - The DOMString to append.

Throws:

org.w3c.dom.DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

deleteData

public final void deleteData(int offset,
                             int count)
                      throws org.w3c.dom.DOMException

Remove a range of characters from the node. Upon success, data and length reflect the change.

Specified by:

deleteData in interface org.w3c.dom.CharacterData

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.

Throws:

org.w3c.dom.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.
