All known Subclasses: org.apache.xerces.impl.xs.opti.TextImpl,
| DefaultText | | public class DefaultText extends NodeImpl implements Text(Code) | | 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.

| Method Summary | |
| public void | appendData(String arg)
Append the string to the end of the character data of the node. | | public void | deleteData(int offset, int count)
Remove a range of 16-bit units from the node. | | public String | getData()
The character data of the node that implements this interface. | | public int | getLength()
The number of 16-bit units that are available through data
and the substringData method below. | | public String | getWholeText()
| | public void | insertData(int offset, String arg)
Insert a string at the specified 16-bit unit offset. | | public boolean | isElementContentWhitespace()
| | public void | replaceData(int offset, int count, String arg)
Replace the characters starting at the specified 16-bit unit offset
with the specified string.
Parameters:
offset - The offset from which to start replacing.
Parameters:
count - The number of 16-bit units to replace. | | public Text | replaceWholeText(String content)
| | public void | setData(String data)
The character data of the node that implements this interface. | | public Text | splitText(int offset)
Breaks this node into two nodes at the specified offset,
keeping both in the tree as siblings. | | public String | substringData(int offset, int count)
Extracts a range of data from the node.
Parameters:
offset - Start offset of substring to extract.
Parameters:
count - The number of 16-bit units to extract. |
| appendData | | public void appendData(String arg) throws DOMException(Code) | | 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.
exception:
DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly. |
| deleteData | | public void deleteData(int offset, int count) throws DOMException(Code) | | Remove a range of 16-bit units from the node. Upon success,
data and length reflect the change.
Parameters:
offset - The offset from which to start removing.
Parameters:
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. |
| getData | | public String getData() throws DOMException(Code) | | 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. |
| getLength | | public int getLength()(Code) | | 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.
|
| insertData | | public void insertData(int offset, String arg) throws DOMException(Code) | | Insert a string at the specified 16-bit unit offset.
Parameters:
offset - The character offset at which to insert.
Parameters:
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. |
| isElementContentWhitespace | | public boolean isElementContentWhitespace()(Code) | | DOM Level 3 CR
|
| replaceData | | public void replaceData(int offset, int count, String arg) throws DOMException(Code) | | Replace the characters starting at the specified 16-bit unit offset
with the specified string.
Parameters:
offset - The offset from which to start replacing.
Parameters:
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 removemethod call with the same range, followed by an appendmethod invocation).
Parameters:
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. |
| setData | | public void setData(String data) throws DOMException(Code) | | 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. |
| splitText | | public Text splitText(int offset) throws DOMException(Code) | | 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.
Parameters:
offset - The 16-bit unit offset at which to split, starting from 0. 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. |
| substringData | | public String substringData(int offset, int count) throws DOMException(Code) | | Extracts a range of data from the node.
Parameters:
offset - Start offset of substring to extract.
Parameters:
count - The number of 16-bit units to extract. 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. |
