Interface TypedStructure

All Known Implementing Classes:

Functor, Predicate, TypedStructureAdapter

public interface TypedStructure

This interface defines method which are given by every TypedStructure like a Predicate or an Functor. It has an name, an arity (argument count) and a list of Sort representing the types for the different arguments.

Method Detail

getName

String getName()

Returns:

the unique name of the structure

setName

void setName(String name)
      throws LanguageException

Changes the name of the Structure

Parameters:

name - The new name of the structure

Throws:

LanguageException - if the new name is illegal in the language.

getArity

int getArity()

Returns:

the arity of this structure

getArgumentTypes

List<Sort> getArgumentTypes()

Returns:

An unmodifiable list which length equals the arity of the predicate if the structure isComplete().

addArgumentType

void addArgumentType(Sort argType)
              throws LanguageException

Adds the given Sort as argument type to the typed Structure

Parameters:

argType - The Sort descibing the argument type

Throws:

LanguageException

removeArgumentType

Sort removeArgumentType(int index)
                 throws LanguageException

Removes the argument type at the specified index

Parameters:

index - The index

Returns:

A reference to the sort that has been remove or null if no sort has been removed.

Throws:

LanguageException, - IndexOutOfBoundsException

LanguageException

removeArgumentType

boolean removeArgumentType(Sort argType)
                    throws LanguageException

Removes the given Sort from the list of argument types

Parameters:

argType - The Sort which is removed

Returns:

true if the Sort exists in the list of argument types and is successfully removed, false otherwise.

Throws:

LanguageException

isTyped

boolean isTyped()

Returns:

true if at least one sort for an argument is not "Thing".

isComplete

boolean isComplete()

Returns:

true if the arity of this structure matches the length of it's arguments, false if the arity is bigger than the length of it's arguments.

clone

TypedStructure clone()

Creates a deep copy of this object

Returns:

A deep copy of this object
