- javax.imageio.metadata.IIOMetadata

```
public abstract class IIOMetadata
extends Object
```
An abstract class to be extended by objects that represent metadata (non-image data) associated with images and streams. Plug-ins represent metadata using opaque, plug-in specific objects. These objects, however, provide the ability to access their internal information as a tree of IIOMetadataNode objects that support the XML DOM interfaces as well as additional interfaces for storing non-textual data and retrieving information about legal data values. The format of such trees is plug-in dependent, but plug-ins may choose to support a plug-in neutral format described below. A single plug-in may support multiple metadata formats, whose names maybe determined by calling getMetadataFormatNames. The plug-in may also support a single special format, referred to as the "native" format, which is designed to encode its metadata losslessly. This format will typically be designed specifically to work with a specific file format, so that images may be loaded and saved in the same format with no loss of metadata, but may be less useful for transfering metadata between an ImageReader and an ImageWriter for different image formats. To convert between two native formats as losslessly as the image file formats will allow, an ImageTranscoder object must be used.

- Method Detail
  - isStandardMetadataFormatSupported
```
public boolean isStandardMetadataFormatSupported()
```
    Returns true if the standard metadata format is supported by getMetadataFormat, getAsTree, setFromTree, and mergeTree.
    The default implementation returns the value of the standardFormatSupported instance variable.
    
    Returns:
    true if the standard metadata format is supported.
    See Also:
    getAsTree(java.lang.String), setFromTree(java.lang.String, org.w3c.dom.Node), mergeTree(java.lang.String, org.w3c.dom.Node), getMetadataFormat(java.lang.String)
  - isReadOnly
```
public abstract boolean isReadOnly()
```
    Returns true if this object does not support the mergeTree, setFromTree, and reset methods.
    
    Returns:
    true if this IIOMetadata object cannot be modified.
  - getNativeMetadataFormatName
```
public String getNativeMetadataFormatName()
```
    Returns the name of the "native" metadata format for this plug-in, which typically allows for lossless encoding and transmission of the metadata stored in the format handled by this plug-in. If no such format is supported, nullwill be returned.
    The structure and contents of the "native" metadata format are defined by the plug-in that created this IIOMetadata object. Plug-ins for simple formats will usually create a dummy node for the root, and then a series of child nodes representing individual tags, chunks, or keyword/value pairs. A plug-in may choose whether or not to document its native format.
    The default implementation returns the value of the nativeMetadataFormatName instance variable.
    
    Returns:
    the name of the native format, or null.

```
public String[] getExtraMetadataFormatNames()
```
    Returns an array of Strings containing the names of additional metadata formats, other than the native and standard formats, recognized by this plug-in's getAsTree, setFromTree, and mergeTree methods. If there are no such additional formats, null is returned.
    The default implementation returns a clone of the extraMetadataFormatNames instance variable.
    
    Returns:
    an array of Strings with length at least 1, or null.
    See Also:
    getAsTree(java.lang.String), setFromTree(java.lang.String, org.w3c.dom.Node), mergeTree(java.lang.String, org.w3c.dom.Node), getNativeMetadataFormatName(), getMetadataFormatNames()

```
public String[] getMetadataFormatNames()
```
    Returns an array of Strings containing the names of all metadata formats, including the native and standard formats, recognized by this plug-in's getAsTree, setFromTree, and mergeTree methods. If there are no such formats, null is returned.
    The default implementation calls getNativeMetadataFormatName, isStandardMetadataFormatSupported, and getExtraMetadataFormatNames and returns the combined results.
    
    Returns:
    an array of Strings.
    See Also:
    getNativeMetadataFormatName(), isStandardMetadataFormatSupported(), getExtraMetadataFormatNames()
  - getMetadataFormat
```
public IIOMetadataFormat getMetadataFormat(String formatName)
```
    Returns an IIOMetadataFormat object describing the given metadata format, or null if no description is available. The supplied name must be one of those returned by getMetadataFormatNames (i.e., either the native format name, the standard format name, or one of those returned by getExtraMetadataFormatNames).
    The default implementation checks the name against the global standard metadata format name, and returns that format if it is supported. Otherwise, it checks against the native format names followed by any additional format names. If a match is found, it retrieves the name of the IIOMetadataFormat class from nativeMetadataFormatClassName or extraMetadataFormatClassNames as appropriate, and constructs an instance of that class using its getInstance method.
    
    Parameters:
    formatName - the desired metadata format.
    
    Returns:
    an IIOMetadataFormat object.
    
    Throws:
    
    IllegalArgumentException - if formatName is null or is not one of the names recognized by the plug-in.
    
    IllegalStateException - if the class corresponding to the format name cannot be loaded.
  - getAsTree
```
public abstract Node getAsTree(String formatName)
```
    Returns an XML DOM Node object that represents the root of a tree of metadata contained within this object according to the conventions defined by a given metadata format.
    The names of the available metadata formats may be queried using the getMetadataFormatNames method.
    
    Parameters:
    formatName - the desired metadata format.
    
    Returns:
    an XML DOM Node object forming the root of a tree.
    
    Throws:
    
    IllegalArgumentException - if formatName is null or is not one of the names returned by getMetadataFormatNames.
    See Also:
    getMetadataFormatNames(), setFromTree(java.lang.String, org.w3c.dom.Node), mergeTree(java.lang.String, org.w3c.dom.Node)
  - mergeTree
```
public abstract void mergeTree(String formatName,
             Node root)
                        throws IIOInvalidTreeException
```
    Alters the internal state of this IIOMetadata object from a tree of XML DOM Nodes whose syntax is defined by the given metadata format. The previous state is altered only as necessary to accomodate the nodes that are present in the given tree. If the tree structure or contents are invalid, an IIOInvalidTreeException will be thrown.
    As the semantics of how a tree or subtree may be merged with another tree are completely format-specific, plug-in authors may implement this method in whatever manner is most appropriate for the format, including simply replacing all existing state with the contents of the given tree.
    
    Parameters:
    formatName - the desired metadata format.
    root - an XML DOM Node object forming the root of a tree.
    
    Throws:
    
    IllegalStateException - if this object is read-only.
    
    IllegalArgumentException - if formatName is null or is not one of the names returned by getMetadataFormatNames.
    
    IllegalArgumentException - if root is null.
    
    IIOInvalidTreeException - if the tree cannot be parsed successfully using the rules of the given format.

  - setController
```
public void setController(IIOMetadataController controller)
```
    Sets the IIOMetadataController to be used to provide settings for this IIOMetadata object when the activateController method is called, overriding any default controller.

    The default implementation sets the controller instance variable to the supplied value.
    
    Parameters:
    controller - An appropriate IIOMetadataController, or null.
    See Also:
    IIOMetadataController, getController(), getDefaultController(), hasController(), activateController()
  - getController
```
public IIOMetadataController getController()
```
    Returns whatever IIOMetadataController is currently installed. This could be the default if there is one, null, or the argument of the most recent call to setController.
    The default implementation returns the value of the controller instance variable.
    
    Returns:
    the currently installed IIOMetadataController, or null.
    See Also:
    IIOMetadataController, setController(javax.imageio.metadata.IIOMetadataController), getDefaultController(), hasController(), activateController()

```
public IIOMetadataController getDefaultController()
```
    Returns the default IIOMetadataController, if there is one, regardless of the currently installed controller. If there is no default controller, returns null.
    The default implementation returns the value of the defaultController instance variable.
    
    Returns:
    the default IIOMetadataController, or null.
    See Also:
    IIOMetadataController, setController(IIOMetadataController), getController(), hasController(), activateController()
  - hasController
```
public boolean hasController()
```
    Returns true if there is a controller installed for this IIOMetadata object.
    The default implementation returns true if the getController method returns a non-null value.
    
    Returns:
    true if a controller is installed.
    See Also:
    IIOMetadataController, setController(IIOMetadataController), getController(), getDefaultController(), activateController()
  - activateController
```
public boolean activateController()
```
    Activates the installed IIOMetadataController for this IIOMetadata object and returns the resulting value. When this method returns true, all values for this IIOMetadata object will be ready for the next write operation. If false is returned, no settings in this object will have been disturbed (i.e., the user canceled the operation).
    Ordinarily, the controller will be a GUI providing a user interface for a subclass of IIOMetadata for a particular plug-in. Controllers need not be GUIs, however.
    The default implementation calls getController and the calls activate on the returned object if hasController returns true.
    
    Returns:
    true if the controller completed normally.
    
    Throws:
    
    IllegalStateException - if there is no controller currently installed.
