Constructor Detail

Filler

public Filler(DataDefinition dataDefinition,
              @LengthType
              long length)
       throws NullPointerException,
              BadLengthException
TODO search out a good description of what a filler does

Creates and initializes a filler segment with a length.

Parameters:
dataDefinition - Kind of data described by the component.
length - Duration measured in edit units of the component.
Throws:
NullPointerException - Data definition is null.
BadLengthException - The length of a filler segment cannot be negative.

Filler

public Filler(DataDefinition dataDefinition)
       throws NullPointerException

Creates and initializes a filler segment without a length.

Parameters:
dataDefinition - Kind of data described by the component.
Throws:
NullPointerException - The data definition argument is null.
Method Detail

setPropertiesFromInterface

public final void setPropertiesFromInterface(Filler castFrom)
See Also:
InterchangeObject.setPropertiesFromInterface(tv.amwa.maj.iface.InterchangeObject)

equals

public boolean equals(Object o)
Description copied from interface: 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.

Specified by:
equals in interface MAJCommon
Overrides:
equals in class Component
Parameters:
o - Object to test for equality with.
Returns:
Is the given object equals to this value?
See Also:
Object.equals(Object)

hashCode

public int hashCode()
Description copied from interface: MAJCommon

Returns a hash code value for this interchange object.

Specified by:
hashCode in interface MAJCommon
Overrides:
hashCode in class Component
Returns:
Hash code value for this interchange object.
See Also:
Object.hashCode()

clone

public Filler clone()
Description copied from interface: 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.

Specified by:
clone in interface MAJCommon
Overrides:
clone in class Segment
Returns:
Independent clone of this value, which is a deep copy.
See Also:
Object.clone()

appendXMLChildren

public void appendXMLChildren(Node parent)
Description copied from interface: 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.

Specified by:
appendXMLChildren in interface XMLSerializable
Overrides:
appendXMLChildren in class Component
Parameters:
parent - XML parent element to append child nodes to.
