Class TypeMapping

java.lang.Object
  net.sourceforge.nrl.parser.type.TypeMapping

All Implemented Interfaces:

ITypeMapping

Direct Known Subclasses:

XmlTypeMapping

public class TypeMapping
extends Object
implements ITypeMapping

A default type mapping implementation. The type mapping is completely empty and can be populated using the add methods before use.

Alternatively, a subclass with a serializer/deserializer method can be used to load and save the mapping to a file, for example XmlTypeMapping.

Method Detail

addAll

public void addAll(TypeMapping other)

Add all entries from another mapping to this one.

Parameters:

other - the mapping to add

addMapping

public TypeMappingEntry addMapping(String packageName,
                                   String typeName,
                                   NRLDataType type)

Add a mapping from a type name, in a particular package, to an internal type. The package can be passed as "*" to indicate that the type is always mapped, no matter where it occurs.

Parameters:

packageName - the package name or "*"

typeName - the type (class/data type) name

type - the target type

clear

public void clear()

Empty the mapping.

contains

public boolean contains(String packageName,
                        String typeName)

Return true if this contains a mapping for a particular package and type name.

Parameters:

packageName - the package

typeName - the type

Returns:

true if found

getMapping

public List<TypeMappingEntry> getMapping()

Return the type mapping entries, in order.

Returns:

the entries

getStringForType

public static String getStringForType(NRLDataType type)

Return a serializable string for the integer constant from NRLDataType. If it is not one of the constants, returns "Unknown".

Parameters:

type - the type value

Returns:

a string value

getTypeFromString

public static NRLDataType getTypeFromString(String type)

Convert a string representation of a type back to an integer number. The string representation is as produced by getStringForType(NRLDataType). If it is not one of this, returns NRLDataType.UNKNOWN.

Parameters:

type - the string

Returns:

the type

getType

public NRLDataType getType(IAttribute attr)

Description copied from interface: ITypeMapping

Map the type of an attribute to an internal abstract type.

Specified by:

getType in interface ITypeMapping

Parameters:

attr - the attribute

Returns:

an NRL type

getType

public NRLDataType getType(IModelElement element)

Description copied from interface: ITypeMapping

Map a model element to an internal, abstract type. If the element is a classifier and not otherwise mapped, it maps to NRLDataType.ELEMENT.

Specified by:

getType in interface ITypeMapping

Parameters:

element - the element

Returns:

an NRL type

remove

public void remove(String packageName,
                   String typeName)

Remove a particular mapping

Parameters:

packageName - the package name

typeName - the type name
