Methods

o clone 
 public abstract Object clone()
Returns an Iterator on the results.

Overrides:
clone in class Object
o isPresent 
 public abstract boolean isPresent(String meta)
Returns true if meta is already in the results, false otherwise.

o elements 
 public abstract Enumeration elements()
returns an Enumration of the elements.

o get 
 public abstract Tree get(String meta)
Returns the tree value that the metavariable meta has matched.

Parameters:
meta - The name of the metavariable.
Returns:
A tree or null.
o getValue 
 public abstract Object getValue(String meta)
Returns the value that the metavariable meta has matched.

Parameters:
meta - The name of the metavariable.
Returns:
An object or null.
o get 
 public abstract IPath get(int extractNumber)
Returns the move to reach the extractNumberth extract position.

Parameters:
extractNumber - The number of the extract pattern (they are numbered in a preorder traversal).
Returns:
A move or null, if this extract position doesn't exist.
o add 
 public abstract Tree add(Metavariable meta,
                          Tree tree)
Sets the value of the metavariable. Adds the metavariable if it is not present.

Parameters:
meta - The metavariable.
tree - The tree value.
Returns:
tree or null if the metavariable can't take that value.
o add 
 public abstract boolean add(Metavariable meta,
                             int i)
Sets the value of the metavariable. Adds the metavariable if it is not present. Checks if the value is compatible with the old value when present.

Parameters:
meta - The metavariable.
i - The integer value.
Returns:
true or false if the metavariable can't take that value.
o add 
 public abstract String add(Metavariable meta,
                            String str)
Sets the value of the metavariable. Adds the metavariable if it is not present. Checks if the value is compatible with the old value when present.

Parameters:
meta - The metavariable.
str - The String value.
Returns:
Str or null if the metavariable can't take that value.
o remove 
 public abstract Metavariable remove(Metavariable meta)
Removes the metavariable of the results.

Returns:
The old value or null if the metavariable is not present.
o add 
 public abstract int add(IPath move)
Sets the value of a new extract postion.

Parameters:
move - The move to the extract position.
Returns:
the number of the extract positon.
o set 
 public abstract int set(int n,
                         IPath move)
Sets the value of a preexistent extract position.

Parameters:
move - The move to the extract position.
Returns:
the number of the extract positon.
o setRootTree 
 public abstract void setRootTree(Tree tree)
o getRootTree 
 public abstract Tree getRootTree()
o setRootPatt 
 public abstract void setRootPatt(Tree tree)
o getRootPatt 
 public abstract Tree getRootPatt()
