Method Details

isReadOnly

public boolean isReadOnly()

Default implementation returns true. Mutable subclasses should override this method.

Specified by:

isReadOnly in class IIOMetadata

Returns:

true.

getAsTree

public Node getAsTree(String formatName)

Specified by:

getAsTree in class IIOMetadata

getNativeTree

protected Node getNativeTree()

Default implementation that throws UnsupportedOperationException. Subclasses that supports formats other than standard metadata should override this method.

Throws:

UnsupportedOperationException

mergeTree

public void mergeTree(String formatName,
 Node root)
               throws IIOInvalidTreeException

Specified by:

mergeTree in class IIOMetadata

Throws:

IIOInvalidTreeException

reset

public void reset()

Specified by:

reset in class IIOMetadata

assertMutable

protected final void assertMutable()

Asserts that this meta data is mutable.

Throws:

IllegalStateException - if isReadOnly() returns true.

validateFormatName

protected final void validateFormatName(String formatName)

toListString

protected static String toListString(short[] values)
