/** The CIMMethod class is used to represent CIM methods in Pegasus.

/** The CIMMethod class is used to represent CIM methods in Pegasus. A Pegasus CIMMethod

consists of the following entities:

<ul>

<li>Name of the method, a CIMName. The name must be a legal name for a

CIMProperty or Method \Ref{CIMName}.

<li>CIM type of the return value of the method, a \Ref{CIMType}. This is any

of the predefined CIM types (for example: Boolean).

<li>Optional qualifiers (see \Ref{CIMQualifier}) for the method. A method

can contain zero or more CIMQualifiers and methods are provided to

manipulate the set of qualifiers attached to a CIMMethod object.

<li>Optional parameters (see \Ref{CIMParameter} for the method which are

the parameters to be placed on a CIM Method operation. A CIMMethod can

contain zero or more CIMParameters and methods are provided in CIMMethod

to manipulate the set of CIMParameters attached to a CIMMethod object.

</ul>

In addition a CIMMethod contains the following internal attributes:

<ul>

<li>propagated - An attribute defining whether this CIMMethod is

propagated from a superclass. Note that this is normally set as part of

completing the definition of objects (resolving) when they are placed in a

repository and is NOT automatically set when creating a local object. It

is part of the context of the object within the repository. It can only

logically be set in context of the superclass of which this CIMMethod is

defined.

<li>ClassOrigin - An attribute defining the superclass in which this

CIMMethod was originally defined. This is normally set within the context

of the CIM Server context of other CIM objects (for example, a

repository). This attribute is available from objects retrieved from the

CIM Server, for example and provides information on the defintion of this method in the class hiearchy

(this object or a superclass or instance of a superclass)was originally

defined. Together the propagated and ClassOrigin attributes can be used

to determine if methods originated with the current object or were

inherited from higher levels in the hiearchy.

</ul>

CIMMethods are generally in the context of a CIMClass.

CIMMethod is a shared class that uses shared representations, meaning that multiple

CIMMethods objects may refer to the came copy of data. Assignment and copy

operators create new references to the same data, not distinct copies. A distinct copy

may be created using teh clone method.
