Interface VarString

All Superinterfaces:

ConstrainedVariable

All Known Implementing Classes:

BasicVarString

public interface VarString
extends ConstrainedVariable

VarString are a special type of constrained variables that are defined using an array of string values.

Method Summary

java.lang.String[]	getAllStrings() Returns all possible strings from the domain of this variable.
int	getIndex(java.lang.String string)
java.lang.String	getInitialDomain()
Var	getInt() Returns the underlying integer constrained variable.
java.lang.String	getValue() Returns a String which is the value to which this variable has been instantiated, throws a RuntimeException if the variable is not instantiated.

Returns all possible strings from the domain of this variable.

Returns:

all possible strings from the domain of this variable.

getIndex

int getIndex(java.lang.String string)

Parameters:

string -

Returns:

an integer index of the "string" inside the domain of this variable.

getInitialDomain

java.lang.String getInitialDomain()

Returns:

a string representing the initial domain of the variable

getInt

Var getInt()

Returns the underlying integer constrained variable.

Returns:

the underlying integer constrained variable.

getValue

java.lang.String getValue()

Returns a String which is the value to which this variable has been instantiated, throws a RuntimeException if the variable is not instantiated.

Returns:

a String which is the value of this instantiated variable.

Throws:

java.lang.RuntimeException - if this variable is not instantiated.

hasSameDomain

boolean hasSameDomain(VarString var)

Parameters:

var -

Returns:

true if this variable has the same domain as "var"

isBound

boolean isBound()

Returns:

true if the variable is bound (domain size is 1)
