Class MappedClassResolver

java.lang.Object
  net.sf.mmm.util.reflect.base.MappedClassResolver

All Implemented Interfaces:

ClassResolver

Direct Known Subclasses:

JavaLangClassResolver

public class MappedClassResolver
extends Object
implements ClassResolver

This is an implementation of the ClassResolver interface that uses an internal Map to define specific mappings. If no mapping is found for the requested type the default strategy Class.forName(String) is used.

Since:

1.0.1

Constructor Detail

MappedClassResolver

public MappedClassResolver()

The constructor.

MappedClassResolver

public MappedClassResolver(MapFactory<? extends Map> mapFactory)

The constructor.

Parameters:

mapFactory - the factory used to create the underlying Map.

Method Detail

addClassMapping

public void addClassMapping(Class<?> type)

This method adds a mapping for the given type using the simple-name.

Parameters:

type - is the type to add.

addClassMapping

public void addClassMapping(String name,
                            Class<?> type)

This method adds a mapping for the given type using the given name.

Parameters:

name - is the name under which the class is mapped.

type - is the mapped class.

resolveClass

public Class<?> resolveClass(String name)

This method resolves the class with the given name. In addition to a ClassLoader this method may also find types via a logical alias name.
The name can be the physical (fully qualified) classname (e.g. org.foo.BlobImpl) but this may also be a logical name depending on the implementation of this interface (e.g. Blob may point to the same type).

Specified by:

resolveClass in interface ClassResolver

Parameters:

name - is the logical or physical name of the requested type.

Returns:

the class reflecting the type with the given name.
