Documentation

An OperationContext object holds information about the context of an operation, using various Container classes. The Container subclasses define the set of information that may be available in the OperationContext.

Inheritance:

Public Methods

	OperationContext () Constructs an empty OperationContext object
	OperationContext (const OperationContext& context) Constructs a copy of an OperationContext object.
virtual	~OperationContext () Destructs the OperationContext
OperationContext&	operator= (const OperationContext& context) Assigns the value of the specified OperationContext object to this OperationContext.
void	clear () Removes all the Containers from the OperationContext
const Container&	get (const String& containerName) const Retrieves the specified Container object from the OperationContext.
Boolean	contains (const String& containerName) const Tests if the specified Container object is in the OperationContext.
void	set (const Container& container) Replaces an OperationContext Container with the specified Container object of the same type.
void	insert (const Container& container) Inserts a Container into the OperationContext.
void	remove (const String& containerName) Removes a Container from the OperationContext.

Public Members

class PEGASUS_COMMON_LINKAGE Container A Container subclass object holds a piece of context information for an operation

Protected Fields

OperationContextRep*

_rep An internal representation of the OperationContext attributes

OperationContext()

Constructs an empty OperationContext object

OperationContext(const OperationContext& context)

Constructs a copy of an OperationContext object. The newly constructed OperationContext object is independent from the source object.

Parameters:

context - The OperationContext object to copy.

virtual ~OperationContext()

Destructs the OperationContext

OperationContext& operator=(const OperationContext& context)

Assigns the value of the specified OperationContext object to this OperationContext. As a result, this OperationContext object will contain the same set of Containers as in the specified object.

Parameters:

context - The OperationContext object to copy.

void clear()

Removes all the Containers from the OperationContext

const Container& get(const String& containerName) const

Retrieves the specified Container object from the OperationContext.

Throws:

Exception if the OperationContext does not contain the specified Container type.

Parameters:

containerName - The name of the Container type to retrieve.

Returns:

A reference to the specified Container object.

Boolean contains(const String& containerName) const

Tests if the specified Container object is in the OperationContext.

Parameters:

containerName - The name of the Container type to retrieve.

Returns:

"true" if the container is present in the OperationContext, "false" if it is not present.

void set(const Container& container)

Replaces an OperationContext Container with the specified Container object of the same type.

Throws:

Exception if the OperationContext does not contain the specified Container type.

Parameters:

container - The Container to set in the OperationContext.

void insert(const Container& container)

Inserts a Container into the OperationContext.

Throws:

Exception if the OperationContext already contains a Container of this type.

Parameters:

container - The Container to insert into the OperationContext.

void remove(const String& containerName)

Removes a Container from the OperationContext.

Throws:

Exception if the OperationContext does not contain the specified Container type.

Parameters:

containerName - The name of the Container type to remove from the OperationContext.
