Deprecated. Creates a new context computer for the given view and help context.

Method Summary

Constructor Detail

ViewContextComputer

public ViewContextComputer(IViewPart viewPart,
                           Object helpContext)

Deprecated.

Creates a new context computer for the given view and help context.

Parameters:

viewPart - the view

helpContext - a single help context id (type String) or help context object (type IContext)

Method Detail

computeContexts

public Object[] computeContexts(HelpEvent event)

Deprecated.

Description copied from interface: IContextComputer

Computes contexts for the help system.

Specified by:

computeContexts in interface IContextComputer

Parameters:

event - the help event which triggered this request for help

Returns:

a mixed-type array of context ids (type String) and/or help contexts (type IContext)

See Also:

IContext

getLocalContexts

public Object[] getLocalContexts(HelpEvent event)

Deprecated.

Description copied from interface: IContextComputer

Returns the local contexts for this context computer.

Typically this method is called by other instances of IContextComputer in their computeContexts method.

The important concept here is that the value returned by computeContexts represents the complete help contexts and is passed directly to the help support system.

However the value returned by this method represents the only the contexts for the particular control with which this IContextComputer is associated.

Specified by:

getLocalContexts in interface IContextComputer

Parameters:

event - the help event which triggered this request for help

Returns:

a mixed-type array of context ids (type String) and/or help contexts (type IContext)
