All Implemented Interfaces:

java.io.Serializable
```
public class ReadArc
extends PTArc
```
If there is an arc a with a weight w=W(p,t) connecting a place p with a transition t, then t can be enabled in a marking m if the following condition is satisfied:
m(p) ≥ w

- Constructor Detail
  - ReadArc
```
public ReadArc()
```
- Method Detail
  - isExecutable
```
public boolean isExecutable()
```
    Returns true if source place has fewer tokens then arc weight.
    
    Overrides:
    
    isExecutable in class Arc
    
    Returns:
    
    true if
    m(p) ≥ w
    false otherwise.
  - execute
```
public void execute()
```
    Does nothing. The token situation on p is not changed by the firing of t, i.e. m'(p) = m(p).
    
    Overrides:
    
    execute in class Arc
  - rollbackExecution
```
public void rollbackExecution(java.lang.Integer tokensConsumed)
```
    Does nothing. The token situation on p is not changed by the firing of t, i.e. m'(p) = m(p).
    
    Overrides:
    
    rollbackExecution in class Arc
  - clone
```
public ReadArc clone()
```
    Overrides:
    
    clone in class Arc
