Interface aioli.vtp.Metavariable

public interface Metavariable
extends Serializable
Defines the notion of metavariable used in pattern expressions.
It's composed of:

Method Index

o clone()
Returns a copy of the metavariable.
o getConstraint()
Returns the constraint associated with the metvariable or null if no constraint is present.
o getMetaClass()
Gives the class of the metavariable.
o name()
Returns the name of the metavariable.
o setConstraint(Constraint)
Sets the constraint of the metavariable.
o setMetaClass(int)
Sets the Class of the metavariable.
o toString()
Converts the value to a String.
o verify(int)
Checks if the class is compatible with the atomic value.
o verify(String)
Checks if the class is compatible with the atomic value.
o verify(Tree)
Checks if the constraint is verified on the tree.

Methods

o setMetaClass 
 public abstract void setMetaClass(int cl)
Sets the Class of the metavariable.

Parameters:
cl - The class of the metavariable.

MetavariableClass
o getMetaClass 
 public abstract int getMetaClass()
Gives the class of the metavariable.

Returns:
The class of the metavariable.

MetavariableClass
o clone 
 public abstract Object clone()
Returns a copy of the metavariable.

Overrides:
clone in class Object
o name 
 public abstract String name()
Returns the name of the metavariable.

o setConstraint 
 public abstract void setConstraint(Constraint constraint)
Sets the constraint of the metavariable.

Parameters:
constraint - The constraint.
o getConstraint 
 public abstract Constraint getConstraint()
Returns the constraint associated with the metvariable or null if no constraint is present.

o verify 
 public abstract boolean verify(Tree tree)
Checks if the constraint is verified on the tree.

Parameters:
tree - The tree we want to check the constraint on.
Returns:
true if the constraint is verified, false otherwise.
o verify 
 public abstract boolean verify(String atr)
Checks if the class is compatible with the atomic value.

Parameters:
str - The String we want to check the constraint on.
Returns:
true if the class is verified, false otherwise.
o verify 
 public abstract boolean verify(int i)
Checks if the class is compatible with the atomic value.

Parameters:
i - The integer we want to check the constraint on.
Returns:
true if the class is verified, false otherwise.
o toString 
 public abstract String toString()
Converts the value to a String.

Overrides:
toString in class Object
