```
public ComponentInputMap(JComponent component)
```
    Creates a ComponentInputMap associated with the specified component.
    
    Parameters:
    
    component - a non-null JComponent
    
    Throws:
    
    IllegalArgumentException - if component is null

  - setParent
```
public void setParent(InputMap map)
```
    Sets the parent, which must be a ComponentInputMap associated with the same component as this ComponentInputMap.
    
    Overrides:
    
    setParent in class InputMap
    
    Parameters:
    
    map - a ComponentInputMap
    
    Throws:
    
    IllegalArgumentException - if map is not a ComponentInputMap or is not associated with the same component
  - getComponent
```
public JComponent getComponent()
```
    Returns the component the InputMap was created for.
  - put
```
public void put(KeyStroke keyStroke,
                Object actionMapKey)
```
    Adds a binding for keyStroke to actionMapKey. If actionMapKey is null, this removes the current binding for keyStroke.
  - remove
```
public void remove(KeyStroke key)
```
    Removes the binding for key from this object.
  - clear
```
public void clear()
```
    Removes all the mappings from this object.
