DefaultText

public class DefaultText extends NodeImpl implements Text
The Text interface inherits from CharacterData and represents the textual content (termed character data in XML) of an Element or Attr. If there is no markup inside an element's content, the text is contained in a single object implementing the Text interface that is the only child of the element. If there is markup, it is parsed into the information items (elements, comments, etc.) and Text nodes that form the list of children of the element.

When a document is first made available via the DOM, there is only one Text node for each block of text. Users may create adjacent Text nodes that represent the contents of a given element without any intervening markup, but should be aware that there is no way to represent the separations between these nodes in XML or HTML, so they will not (in general) persist between DOM editing sessions. The normalize() method on Node merges any such adjacent Text objects into a single node for each block of text.

See also the Document Object Model (DOM) Level 2 Core Specification. This is an empty implementation.

Fields Summary
Constructors Summary
Methods Summary
public voidappendData(java.lang.String 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.

param
arg The DOMString to append.
exception
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public voiddeleteData(int offset, int count)
Remove a range of 16-bit units from the node. Upon success, data and length reflect the change.

param
offset The offset from which to start removing.
param
count The number of 16-bit units to delete. If the sum of offset and count exceeds length then all 16-bit units from offset to the end of the data are deleted.
exception
DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public java.lang.StringgetData()
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.

exception
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
exception
DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

        return null;
public intgetLength()
The number of 16-bit units that are available through data and the substringData method below. This may have the value zero, i.e., CharacterData nodes may be empty.

        return 0;
public java.lang.StringgetWholeText()

        throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public voidinsertData(int offset, java.lang.String arg)
Insert a string at the specified 16-bit unit offset.

param
offset The character offset at which to insert.
param
arg The DOMString to insert.
exception
DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public booleanisElementContentWhitespace()
DOM Level 3 CR

        throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public voidreplaceData(int offset, int count, java.lang.String arg)
Replace the characters starting at the specified 16-bit unit offset with the specified string.

param
offset The offset from which to start replacing.
param
count The number of 16-bit units to replace. If the sum of offset and count exceeds length, then all 16-bit units 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).
param
arg The DOMString with which the range must be replaced.
exception
DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data, or if the specified count is negative.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public org.w3c.dom.TextreplaceWholeText(java.lang.String content)

        throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public voidsetData(java.lang.String data)
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.

exception
DOMException NO_MODIFICATION_ALLOWED_ERR: Raised when the node is readonly.
exception
DOMException DOMSTRING_SIZE_ERR: Raised when it would return more characters than fit in a DOMString variable on the implementation platform.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public org.w3c.dom.TextsplitText(int offset)
Breaks this node into two nodes at the specified offset, keeping both in the tree as siblings. After being split, this node will contain all the content up to the offset point. A new node of the same type, which contains all the content at and after the offset point, is returned. If the original node had a parent node, the new node is inserted as the next sibling of the original node. When the offset is equal to the length of this node, the new node has no data.

param
offset The 16-bit unit offset at which to split, starting from 0.
return
The new node, of the same type as this node.
exception
DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units in data.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
public java.lang.StringsubstringData(int offset, int count)
Extracts a range of data from the node.

param
offset Start offset of substring to extract.
param
count The number of 16-bit units to extract.
return
The specified substring. If the sum of offset and count exceeds the length, then all 16-bit units to the end of the data are returned.
exception
DOMException INDEX_SIZE_ERR: Raised if the specified offset is negative or greater than the number of 16-bit units 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.

    	throw new DOMException(DOMException.NOT_SUPPORTED_ERR, "Method not supported");
