| Object | PDSAttrObj |
A PDSAttrObj represents a structure attribute object, which is a Cos dictionary or stream describing attributes associated with a PDSElement. The attribute's data may be application-specific, suiting the application that adds or extracts logical structure information. An attribute object can have a revision number to indicate whether other applications have modified either the associated element or the element's contents since the application created or modified the element.

|
Creates a new attribute object with the specified owner.
|

|
Creates an attribute object with the specified owner from the specified Cos stream.

|
CosObj PDSAttrObjGetCosObj(PDSAttrObj attrObj)
Gets the Cos object corresponding to the specified attribute object. This method does not copy the object, but is instead the logical equivalent of a type cast.
|

|
ASAtom PDSAttrObjGetOwner(INPDSAttrObj element)
Gets the value of the key (Owner) in the specified attribute object.
