public class VMVariableCtx
extends VariableCtx

The VMVariableCtx maintains information regarding the binding of a variable defined for a frame and bound in a frame context. The binding of a variable can be one or more values depending on the type of variable and depending on the binding of the variable in a precondition or activity.

Constructor Detail

VMVariableCtx

public VMVariableCtx(Variable var)
              throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Constructor, creates a new context for a variable bound in a specific frame context. Initially the variable is unbound, meaning no values are bound to the variable.

Parameters:

var - the variable for which this variable context is the context

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if an internal error occurs

VMVariableCtx

public VMVariableCtx(Variable var,
                     FrameCtx frame)
              throws gov.nasa.arc.brahms.common.exceptions.BrahmsException

Constructor, creates a new context for a variable bound in a specific frame context. Initially the variable is unbound, meaning no values are bound to the variable.

Parameters:

var - the variable for which this variable context is the context

frame - the frame context in which the variable is bound

Throws:

gov.nasa.arc.brahms.common.exceptions.BrahmsException - if frame is null
