| Constructor Summary | |
| protected | Edge(Place place, String expression)
Creates a new edge, with the provided weight expression and
connected place. |
| Method Summary | |
| protected int | eval(Case caze)
Evaluates an integer expression representing the edge weight
using the case attributes. | | Place | getPlace()
Returns the place this edge is connected to. | | int | input(Case caze)
Returns the weight of a precondition edge. | | static Edge | newInput(Place place, String expression)
Creates a new input edge, with the transition precondition
weight expression and source place. | | static Edge | newOutput(Place place, String expression)
Creates a new output edge, with the transition postcondition
weight expression and sink place. | | int | output(Case caze)
Returns the weight of a postcondition edge. | | public String | toString()
Returns a string with the condition expression. | | int | weight(Case caze)
Returns the weight of this edge. |
| Edge | | protected Edge(Place place, String expression)(Code) | | Creates a new edge, with the provided weight expression and
connected place. For an input edge the connected place will be a
source place, and for an output edge it will be a sink place.
Parameters:
place - the connected place.
Parameters:
expression - the weight expression. |
| eval | | protected int eval(Case caze) throws EvaluationException(Code) | | Evaluates an integer expression representing the edge weight
using the case attributes.
Parameters:
caze - the case that contains the attributes. The value of the expression, a positive integer.
exception:
EvaluationException - if an expression evaluation erroroccurs. |
| getPlace | | Place getPlace()(Code) | | Returns the place this edge is connected to. For an input edge the
connected place will be a source place, and for an output edge it
will be a sink place.
the place this edge is connected to. |
| input | | int input(Case caze) throws EvaluationException(Code) | | Returns the weight of a precondition edge.
A positive integer if this edge is a precondition,zero otherwise.
exception:
EvaluationException - if an expression evaluation erroroccurs. |
| newInput | | static Edge newInput(Place place, String expression)(Code) | | Creates a new input edge, with the transition precondition
weight expression and source place.
Parameters:
place - the connected place.
Parameters:
expression - the weight expression. the input edge. |
| newOutput | | static Edge newOutput(Place place, String expression)(Code) | | Creates a new output edge, with the transition postcondition
weight expression and sink place.
Parameters:
place - the connected place.
Parameters:
expression - the expression. the output edge. |
| output | | int output(Case caze) throws EvaluationException(Code) | | Returns the weight of a postcondition edge.
A positive integer if this edge is a precondition,zero otherwise.
exception:
EvaluationException - if an expression evaluation erroroccurs. |
| toString | | public String toString()(Code) | | Returns a string with the condition expression.
a string representation of this edge. |
| weight | | int weight(Case caze) throws EvaluationException(Code) | | Returns the weight of this edge.
A negative, zero, or a positive integer as this edge is aprecondition, no-condition, or a postcondition.
exception:
EvaluationException - if an expression evaluation erroroccurs. |
