Method Detail

isConstant

public static boolean isConstant(String string)

Deprecated.

Checks whether the input string matches the constant pattern. A constant must start with a number or a non-capital letter. It is a alpha-numeric word and can have the symbol _.

This method is used to throw exceptions in stringToConstant().

Parameters:

string - that is the constant.

Returns:

true if the string correspond to the constant pattern.

stringToConstant

public static Constant stringToConstant(String string)
                                 throws RemoteException

Deprecated.

Converts the input string into a Constant object. The input string should be a constant.

Parameters:

string - to be converted into the Constant object.

Returns:

the Constant object representing the constant string input.

Throws:

RemoteException - if the input does not correspond to a constant according to the method isConstant().

See Also:

Constant, isConstant(String)

isVariable

public static boolean isVariable(String string)

Deprecated.

Checks whether the input string matches the variable pattern. A variable must start a capital letter. It is a alpha-numeric word and can have the symbol _.

This method is used to throw exceptions in stringToVariable().

Parameters:

string - that is the variable.

Returns:

true if the string correspond to the variable pattern.

stringToVariable

public static Variable stringToVariable(String string,
                        HashMap<String,Variable> variables)
                                 throws RemoteException

Deprecated.

Converts the input string into a Variable object. The input string should be a variable.

The variable variables is used to pass the variables created to the whole clause to avoid to create two different variables for the same one. Initialize it with null or a brand new HashMap.

Parameters:

string - to be converted into the Variable object.

variables - the variables already created to be reused if necessary and it will be updated with the new created variables.

Returns:

the Variable object representing the variable string input.

Throws:

RemoteException - if the input does not correspond to a variable according to the method isVariable().

See Also:

Variable, isVariable(String)

isSimpleSentence

public static boolean isSimpleSentence(String string)

Deprecated.

Checks whether the input string matches the simple sentence pattern. It is a predicate or an event. This string has the form of: 'constant(parameters)' where 'parameters' are variables or constants separate by a comma. Constants and variables are checks thanks to their own methods: isConstant() and isVariable().

See a Prolog documentation for more information about Prolog predicate. This method is used to throw exceptions in stringToSimpleSentence().

This method is used to throw exceptions in stringToSimpleSentence().

Parameters:

string - to be checked whether it is a simple sentence or not.

Returns:

true if it matches the general form of a simple sentence, otherwise false.
