{
        String owner = dictionary.getNameAsString(COSName.O);
        if (PDUserAttributeObject.USER_PROPERTIES.equals(owner))
        {

        }
        return new PDDefaultAttributeObject(dictionary);
}

Creates an attribute object.

 public String getOwner() 
{
        return this.getCOSDictionary().getNameAsString(COSName.O);
}

Returns the owner of the attributes.

 public boolean isEmpty() 
{
        // only entry is the owner?
        return (this.getCOSDictionary().size() == 1) && (this.getOwner() != null);
}

Detects whether there are no properties in the attribute object.

 protected  void notifyChanged() 
{
        if (this.getStructureElement() != null)
        {
            this.getStructureElement().attributeChanged(this);
        }
}

Notifies the attribute object change listeners about a change in this attribute object.

 protected  void potentiallyNotifyChanged(Object oldValue,
    Object newValue) 
{
        if (this.isValueChanged(oldValue, newValue))
        {
            this.notifyChanged();
        }
}

Notifies the attribute object change listeners if the attribute is changed.

 protected  void setOwner(String owner) 
{
        this.getCOSDictionary().setName(COSName.O, owner);
}

Sets the owner of the attributes.

 protected  void setStructureElement(PDStructureElement structureElement) 
{
        this.structureElement = structureElement;
}

Sets the structure element.
