Class DefaultText

  • All Implemented Interfaces:
    CharacterData, Node, Text
    Direct Known Subclasses:
    TextImpl
    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.

      • 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.

      • setData

        public void setData​(String data)
             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:
        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.

      • 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

      • 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.

      • 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.

      • 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.

      • 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.

      • 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.

      • 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.
