Constructor Detail

TypedStructureAdapter

public TypedStructureAdapter()

Default-Ctor: Creating empty typed structure

TypedStructureAdapter

public TypedStructureAdapter(String name)

Initializes a structure of arity zero with the given name;

Parameters:

name - the name of the structure

TypedStructureAdapter

public TypedStructureAdapter(String name,
                             int arity)

Initializes a structure with the given name and of the given arity. Every argument gets the sort Sort.THING.

Parameters:

name - the name of the structure

TypedStructureAdapter

public TypedStructureAdapter(String name,
                             List<Sort> arguments)

Initializes a structure with the given name and the given list of argument sorts.

Parameters:

name - the name of the structure

arguments - the sorts of the arguments

Method Detail

getName

public String getName()

Specified by:

getName in interface TypedStructure

Returns:

the unique name of the structure

setName

public void setName(String name)

Description copied from interface: TypedStructure

Changes the name of the Structure

Specified by:

setName in interface TypedStructure

Parameters:

name - The new name of the structure

getArity

public int getArity()

Specified by:

getArity in interface TypedStructure

Returns:

the arity of this structure

setArity

public void setArity(int arity)

Description copied from interface: TypedStructure

Sets the arity of this structure

Specified by:

setArity in interface TypedStructure

Parameters:

arity - the new arity

getArgumentTypes

public List<Sort> getArgumentTypes()

Specified by:

getArgumentTypes in interface TypedStructure

Returns:

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

addArgumentType

public void addArgumentType(Sort argType)

Description copied from interface: TypedStructure

Adds the given Sort as argument type to the typed Structure

Specified by:

addArgumentType in interface TypedStructure

Parameters:

argType - The Sort descibing the argument type

removeArgumentType

public Sort removeArgumentType(int index)

Description copied from interface: TypedStructure

Removes the argument type at the specified index

Specified by:

removeArgumentType in interface TypedStructure

Parameters:

index - The index

Returns:

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

removeArgumentType

public boolean removeArgumentType(Sort argType)

Description copied from interface: TypedStructure

Removes the given Sort from the list of argument types

Specified by:

removeArgumentType in interface TypedStructure

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.

isTyped

public boolean isTyped()

Specified by:

isTyped in interface TypedStructure

Returns:

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

isComplete

public boolean isComplete()

Specified by:

isComplete in interface TypedStructure

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.
