Class IIOMetadataNode

java.lang.Object
javax.imageio.metadata.IIOMetadataNode
All Implemented Interfaces:
Element, Node, NodeList 
public class IIOMetadataNode extends Object implements Element, NodeList
A class representing a node in a meta-data tree, which implements the org.w3c.dom.Element interface and additionally allows for the storage of non-textual objects via the getUserObject and setUserObject methods.

This class is not intended to be used for general XML processing. In particular, Element nodes created within the Image I/O API are not compatible with those created by Sun's standard implementation of the org.w3.dom API. In particular, the implementation is tuned for simple uses and may not perform well for intensive processing.

Namespaces are ignored in this implementation. The terms "tag name" and "node name" are always considered to be synonymous. Note: The DOM Level 3 specification added a number of new methods to the Node, Element and Attr interfaces that are not of value to the IIOMetadataNode implementation or specification. Calling such methods on an IIOMetadataNode, or an Attr instance returned from an IIOMetadataNode will result in a DOMException being thrown.

Returns:
The Attr value as a string, or the empty string if that attribute does not have a specified or default value.
See Also:

setAttribute

public void setAttribute(String name, String value)
Description copied from interface: Element
Adds a new attribute. If an attribute with that name is already present in the element, its value is changed to be that of the value parameter. This value is a simple string; it is not parsed as it is being set. So any markup (such as syntax to be recognized as an entity reference) is treated as literal text, and needs to be appropriately escaped by the implementation when it is written out. In order to assign an attribute value that contains entity references, the user must create an Attr node plus any Text and EntityReference nodes, build the appropriate subtree, and use setAttributeNode to assign it as the value of an attribute.
To set an attribute with a qualified name and namespace URI, use the setAttributeNS method.
Specified by:
setAttribute in interface Element
Parameters:
name - The name of the attribute to create or alter.
value - Value to set in string form.

setAttributeNS

public void setAttributeNS(String namespaceURI, String qualifiedName, String value)
Equivalent to setAttribute(qualifiedName, value).
Specified by:
setAttributeNS in interface Element
Parameters:
namespaceURI - The namespace URI of the attribute to create or alter.
qualifiedName - The qualified name of the attribute to create or alter.
value - The value to set in string form.
See Also:

removeAttribute

public void removeAttribute(String name)
Description copied from interface: Element
Removes an attribute by name. If a default value for the removed attribute is defined in the DTD, a new attribute immediately appears with the default value as well as the corresponding namespace URI, local name, and prefix when applicable. The implementation may handle default values from other schemas similarly but applications should use Document.normalizeDocument() to guarantee this information is up-to-date.
If no attribute with this name is found, this method has no effect.
To remove an attribute by local name and namespace URI, use the removeAttributeNS method.
Specified by:
removeAttribute in interface Element
Parameters:
name - The name of the attribute to remove.

removeAttributeNS

public void removeAttributeNS(String namespaceURI, String localName)
Equivalent to removeAttribute(localName).
Specified by:

Parameters:
namespaceURI - The namespace URI of the attribute to remove.
localName - The local name of the attribute to remove.

getAttributeNode

public Attr getAttributeNode(String name)
Description copied from interface: Element
Retrieves an attribute node by name.
To retrieve an attribute node by qualified name and namespace URI, use the getAttributeNodeNS method.
Specified by:
getAttributeNode in interface Element
Parameters:
name - The name (nodeName) of the attribute to retrieve.
Returns:
The Attr node with the specified name ( nodeName) or null if there is no such attribute.

getAttributeNodeNS

public Attr getAttributeNodeNS(String namespaceURI, String localName)
Equivalent to getAttributeNode(localName).
Specified by:
getAttributeNodeNS in interface Element
Parameters:
namespaceURI - The namespace URI of the attribute to retrieve.
localName - The local name of the attribute to retrieve.
Returns:
The Attr node with the specified attribute local name and namespace URI or null if there is no such attribute.
See Also:

setAttributeNode

public Attr setAttributeNode(Attr newAttr) throws DOMException
Description copied from interface: Element
Adds a new attribute node. If an attribute with that name ( nodeName) is already present in the element, it is replaced by the new one. Replacing an attribute node by itself has no effect.
To add a new attribute node with a qualified name and namespace URI, use the setAttributeNodeNS method.
Specified by:
setAttributeNode in interface Element
Parameters:
newAttr - The Attr node to add to the attribute list.
Returns:
If the newAttr attribute replaces an existing attribute, the replaced Attr node is returned, otherwise null is returned.
Throws:
DOMException - WRONG_DOCUMENT_ERR: Raised if newAttr was created from a different document than the one that created the element.
NO_MODIFICATION_ALLOWED_ERR: Raised if this node is readonly.
INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of another Element object. The DOM user must explicitly clone Attr nodes to re-use them in other elements.

setAttributeNodeNS

public Attr setAttributeNodeNS(Attr newAttr)
Equivalent to setAttributeNode(newAttr).
Specified by:
setAttributeNodeNS in interface Element
Parameters:
newAttr - The Attr node to add to the attribute list.
Returns:
If the newAttr attribute replaces an existing attribute with the same local name and namespace URI, the replaced Attr node is returned, otherwise null is returned.
See Also:

removeAttributeNode

public Attr removeAttributeNode(Attr oldAttr)
Description copied from interface: Element
Removes the specified attribute node. If a default value for the removed Attr node is defined in the DTD, a new node immediately appears with the default value as well as the corresponding namespace URI, local name, and prefix when applicable. The implementation may handle default values from other schemas similarly but applications should use Document.normalizeDocument() to guarantee this information is up-to-date.
Specified by:
removeAttributeNode in interface Element
Parameters:
oldAttr - The Attr node to remove from the attribute list.
Returns:
The Attr node that was removed.
