@AAFClass(uuid1=218169601, uuid2=257, uuid3=17152, uuid4={6,14,43,52,2,6,1,1}, definedName="DataEssenceDescriptor", description="Specifies that a file source mob is associated with data essence.") public class DataEssenceDescriptor
Implements the description of a file of data essence and identifies the data coding of that essence. Data essence includes that specified in MXF mappings for MPEG (SMPTE 381M), DV (SMPTE 383M), D10 and D11 (SMPTE 386M). Data essence often refers to time-varying data, such as subtitles (closed captions).

Creates and initializes a new data essence descriptor, which specifies that a
file source mob
is associated with data essence.
containerFormat
- Container format of the associated data essence.
NullPointerException
- The container format argument is null

DataEssenceDescriptor
Returns the data essence coding property of this data essence descriptor.
getDataEssenceCoding
in interface DataEssenceDescriptor
PropertyNotPresentException
- The optional data essence coding property
is not present in this data essence descriptor.public void setDataEssenceCoding(AUID dataEssenceCoding)
DataEssenceDescriptor
Sets the data essence coding property of this data essence descriptor. Setting
this optional property to null
omits the property.
setDataEssenceCoding
in interface DataEssenceDescriptor
dataEssenceCoding
- Data essence coding property of this data essence descriptor.public boolean equals(Object o)
MAJCommon
Tests to see if the given object is equal to this interchange object. To be equal, the given value must be not null, share the same interface to its value and each of the properties of the value must each be equal.
equals
in interface MAJCommon
equals
in class AAFFileDescriptor
o
- Object to test for equality with.
Object.equals(Object)
public int hashCode()
MAJCommon
Returns a hash code value for this interchange object.

in interface MAJCommon
hashCode
in class AAFFileDescriptor
Object.hashCode()
public DataEssenceDescriptor clone()
MAJCommon
Creates a cloned copy of this entity. The clone will be initialized to have the same value as this value but exists independently from then on. Changes to this value will not effect the clone and changes to the clone will not effect this. MAJ API clones are true deep clones with no shared references to areas of memory within the original.
This method does not throw a CloneNotSupportedException
as all
entity values must implement the Cloneable
interface. If a cloning
error does occur, a null
value will be returned but this is very unlikely
to happen.

in interface MAJCommon

in class EssenceDescriptor
Object.clone()
public void appendXMLChildren(Node parent)
XMLSerializable
Append child elements to the given parent node to serialize the value of an object
to an XML fragment. Methods of the XMLBuilder
class are provided to help with this
process.
appendXMLChildren
in interface XMLSerializable
appendXMLChildren
in class AAFFileDescriptor
parent
- XML parent element to append child nodes to.
