NAME
XDF::BaseObject - Perl Class for BaseObject
SYNOPSIS
...
DESCRIPTION
XDF is the eXtensible Data Structure, which is an XML format designed to contain n-dimensional scientific/mathematical data.
XDF::BaseObject is the base class that all other XDF object classes inherit from. It supplies general use methods to these sub classes. (Diagram of object structure??)
Most other XDF objects inherit the methods of XDF::BaseObject.XDF::BaseObject inherits class and attribute methods of XDF::GenericObject .
METHODS
CLASS Methods
The following methods are defined for the class XDF::BaseObject.
-
- getClassAttributes (EMPTY)

The following instance (object) methods are defined for XDF::BaseObject.
-
- getXMLAttributes (EMPTY)
-
Return a list reference of the XML attributes held by this object. This list *may* differ from that returned by getClassXMLAttributesas new, user-defined Attributes may have been added to this instance.
- setXMLAttributes ($attribHashRef)
-

- setXMLAttribute ($attrib, $value)
-
- addXMLAttribute ($attrib, $value)

- toXMLFileHandle ($fileHandle, $XMLDeclAttribs, $indent, $dontCloseNode, $newNodeNameString, $noChildObjectNodeName)
-
Write this structure and all the objects it owns to the supplied filehandle in XML (XDF) format. The first argument is the name of the filehandle and is required.
- toXMLString ($XMLDeclAttribs, $indent, $dontCloseNode, $newNodeNameString, $noChildObjectNodeName)
-
Print out the XML representation of this object. Similar to toXMLFileHandle method, takes the same arguments barring thefirst (e.g. the FileHandle reference) which is not needed for this method. Returns a string XML representation of the object.
- toXMLFile ($file, $XMLDeclAttribs)
-
This is a convenience method which allows writing of this object and all the objects it owns to the indicated file in XML (XDF) format. The first argument is the name of the file and is required.
