- Method Detail
  - getBindableVars
```
java.util.Collection<? extends AtomVariable> getBindableVars(java.util.Collection<AtomVariable> bound)
```
    Parameters:
    
    bound -
    
    Returns:
    
    a set of variables which this binding helper can bind.
  - getPrerequisiteVars
```
java.util.Collection<? extends AtomVariable> getPrerequisiteVars(java.util.Collection<AtomVariable> bound)
```
    Parameters:
    
    bound -
    
    Returns:
    
    a set of variables which must be bound before this helper can generate bindings.
  - rebind
```
void rebind(VariableBinding newBinding)
```
    Set the incoming binding for this helper. This fixes any variables that are already bound by a preceding Binding Helper.
    
    Parameters:
    
    newBinding - Binding map. Implementation will copy map if needed.
  - selectNextBinding
```
boolean selectNextBinding()
```
    Selects the next binding.
    
    Returns:
    
    True if a binding was available for this pattern given the initial binding. False otherwise. Will return if the binding is not set.
  - setCurrentBinding
```
void setCurrentBinding(VariableBinding currentBinding)
```
    Set the variables this pattern uses in the given map.
    
    Parameters:
    
    currentBinding -
