Constructor Detail

BasicManager

public BasicManager()

Method Detail

init

public void init(BasicClassLoader classloader)

Deprecated. Basic ClassLoader is not a classloader. Need refactoring (Christophe Ney)

Initializes the current Manager. This method replaces the constructor method, with a single parameter, which is a class loader.

Specified by:

init in interface Manager

Parameters:

classloader - a single class loader to load class into the meta information

init

public void init()

Initializes the current Manager with no specific classloader

Specified by:

init in interface Manager

getSchema

public Schema getSchema(java.lang.String schemaName)

Returns an existing schema. If no Schema corresponds to the given name, null is returned.

Specified by:

getSchema in interface Manager

Parameters:

schemaName - the name of the schema

Returns:

a Schema object. If the schema does not exist, null is returned.

createSchema

public Schema createSchema(java.lang.String schemaName)

Returns a new schema. This method is the factory method to create schema object. If the schemaName schema already exists, it is returned.

Specified by:

createSchema in interface Manager

Parameters:

schemaName - the name of the schema

Returns:

a new schema object, or the existing one if already defined

iterateSchema

public java.util.Iterator iterateSchema()

Allows to know all the declared schemas into the current metainformation manager. This iterator contains Schema object.

Specified by:

iterateSchema in interface Manager

Returns:

an iterator on registered Schema object. If there is no schema, an empty iterator is returned.

addMappingFactory

public void addMappingFactory(java.lang.String mapperName,
                              java.lang.String mappingFactory)

Adds a mapping factory to the current metainformation manager. A mapping factory is a factory to map object (class, field, ...).

Specified by:

addMappingFactory in interface Manager

Parameters:

mapperName - the name of the mapper (i.e: OR for rdb)

mappingFactory - the mapping factory to add to the list of existing mapping factories

getMappingFactory

public MappingFactory getMappingFactory(java.lang.String mapperName)

Returns a mapping factory corresponding to a mapper name. If no MappingFactory corresponds to the mapper name, null is returned.

Specified by:

getMappingFactory in interface Manager

Parameters:

mapperName - the name of the mapper to obtain

Returns:

a mapping factory. If the mapping factory does not exist for the mapper, null is returned.

getClass

public Class getClass(java.lang.String className)

searches a class into all the declared schemas and returns it. If no class corresponds to this name, null is returned.

Specified by:

getClass in interface Manager

Parameters:

className - the name of the class to search

Returns:

the Class object found, null if not found.

getPTypeSpace

public PTypeSpace getPTypeSpace()

TBD

Specified by:

getPTypeSpace in interface Manager

getParent

public MetaObject getParent()

Allows to know the parent MetaObject of the current MetaObject.

Specified by:

getParent in interface MetaObject

Returns:

the MetaObject corresponding to the parent of the current object. If there is no parent, null is returned.

setParent

public void setParent(MetaObject itsParent)

Set the parent of the current meta object if it is not yet done by the constructor of the meta object

Specified by:

setParent in interface MetaObject

Parameters:

itsParent - the parent MetaObject of the current object

setLogger

public void setLogger(org.objectweb.util.monolog.api.Logger logger)

Defines a logger object.

Specified by:
