Constructor Detail

TextImpl

public TextImpl(Node node)

Method Detail

isComment

public boolean isComment()

Retrieves whether this object represents a comment.

Specified by:: isComment in interface javax.xml.soap.Text

getValue

public String getValue()

Description copied from class: NodeImpl

Returns the value of this node if this is a Text node or the value of the immediate child of this node otherwise.

If there is an immediate child of this Node that it is a Text node then it's value will be returned. If there is more than one Text node then the value of the first Text Node will be returned. Otherwise null is returned.

Specified by:: getValue in interface javax.xml.soap.Node
Overrides:: getValue in class NodeImpl

Returns:: a String with the text of this node if this is a Text node or the text contained by the first immediate child of this Node object that is a Text object if such a child exists; null otherwise.

setValue

public void setValue(String value)

Description copied from class: NodeImpl

If this is a Text node then this method will set its value, otherwise it sets the value of the immediate (Text) child of this node.

The value of the immediate child of this node can be set only if, there is one child node and that node is a Text node, or if there are no children in which case a child Text node will be created.

Specified by:: setValue in interface javax.xml.soap.Node
Overrides:: setValue in class NodeImpl

Parameters:: value - A value string

splitText

public Text splitText(int offset)
               throws DOMException

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.

Specified by:: splitText in interface Text

Parameters:: offset - The 16-bit unit offset at which to split, starting from 0.
Returns:: The new node, of the same type as this node.
Throws:: 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.

getLength

public int getLength()

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.

Specified by:: getLength in interface CharacterData

deleteData

public void deleteData(int offset,
                       int count)
                throws DOMException

Remove a range of 16-bit units from the node. Upon success, data and length reflect the change.

Specified by:: deleteData in interface CharacterData

Parameters:: offset - The offset from which to start removing.; 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.
Throws:: 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

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 CharacterData

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

substringData

public String substringData(int offset,
                            int count)
                     throws DOMException

Extracts a range of data from the node.

Specified by:: substringData in interface CharacterData

Parameters:: offset - Start offset of substring to extract.; count - The number of 16-bit units to extract.
Returns:: 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.
Throws:: 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.

replaceData

public void replaceData(int offset,
                        int count,
                        String arg)
                 throws DOMException

Replace the characters starting at the specified 16-bit unit offset with the specified string.

Specified by:: replaceData in interface CharacterData

Parameters:: offset - The offset from which to start replacing.; 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).; arg - The DOMString with which the range must be replaced.
Throws:: 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.

insertData

public void insertData(int offset,
                       String arg)
                throws DOMException

Insert a string at the specified 16-bit unit offset.

Specified by:: insertData in interface CharacterData

Parameters:: offset - The character offset at which to insert.; arg - The DOMString to insert.
Throws:: 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.

appendData

public void appendData(String arg)
                throws 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 CharacterData

Parameters:: arg - The DOMString to append.
Throws:: DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.

setData

public void setData(String data)
             throws DOMException

Specified by:: setData in interface CharacterData

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

isElementContentWhitespace

public boolean isElementContentWhitespace()

TODO - complete the implementation Returns whether this text node contains element content whitespace, often abusively called "ignorable whitespace". The text node is determined to contain whitespace in element content during the load of the document or if validation occurs while using Document.normalizeDocument().

Since:: DOM Level 3

getWholeText

public String getWholeText()

TODO - complete the implementation Returns all text of Text nodes logically-adjacent text nodes to this node, concatenated in document order.
For instance, in the example below wholeText on the Text node that contains "bar" returns "barfoo", while on the Text node that contains "foo" it returns "barfoo".

Since:: DOM Level 3

replaceWholeText

public Text replaceWholeText(String content)
                      throws DOMException

TODO - complete the implementation Replaces the text of the current node and all logically-adjacent text nodes with the specified text. All logically-adjacent text nodes are removed including the current node unless it was the recipient of the replacement text.
This method returns the node which received the replacement text. The returned node is:

null, when the replacement text is the empty string;
the current node, except when the current node is read-only;
a new Text node of the same type ( Text or CDATASection) as the current node inserted at the location of the replacement.

For instance, in the above example calling replaceWholeText on the Text node that contains "bar" with "yo" in argument results in the following:
Where the nodes to be removed are read-only descendants of an EntityReference, the EntityReference must be removed instead of the read-only nodes. If any EntityReference to be removed has descendants that are not EntityReference, Text, or CDATASection nodes, the replaceWholeText method must fail before performing any modification of the document, raising a DOMException with the code NO_MODIFICATION_ALLOWED_ERR.
For instance, in the example below calling replaceWholeText on the Text node that contains "bar" fails, because the EntityReference node "ent" contains an Element node which cannot be removed.

Parameters:: content - The content of the replacing Text node.
Returns:: The Text node created with the specified content.
Throws:: DOMException - NO_MODIFICATION_ALLOWED_ERR: Raised if one of the Text nodes being replaced is readonly.
Since:: DOM Level 3
