Method Detail

loadProperties

public void loadProperties(java.util.Properties properties)

Loads a set of properties (key and element pairs) from the specified property set.

Specified by:

loadProperties in class JImplementationRepository

Parameters:

properties - a set of properties

create

public java.lang.Object create(java.lang.Class abstractType)
                        throws java.lang.IllegalArgumentException

Creates the object which is the implementation of the specified abstract type. The concrete implementation class, associated with the specified abstract type, will be found into this repository, and then it will be instantiated.

Specified by:

create in class JImplementationRepository

Parameters:

abstractType - an abstract type

Returns:

the implementation of the specified abstract type

Throws:

java.lang.IllegalArgumentException - if the specified abstract type is unknown by this repository

create

public java.lang.Object create(java.lang.String item)
                        throws java.lang.IllegalArgumentException

Creates the object which implementation is associated with the specified String. The concrete implementation class, associated with the specified String item, will be found into this repository, and then it will be instantiated.

Specified by:

create in class JImplementationRepository

Parameters:

item - a String item associated with a concrete implementation

Returns:

the implementation desgined by the specified String item

Throws:

java.lang.IllegalArgumentException - if the specified String item is unknown by this repository

create

public java.lang.Object create(int item)
                        throws java.lang.IllegalArgumentException

Creates the object which implementation is associated with the specified integer. The concrete implementation class, associated with the specified int item, will be found into this repository, and then it will be instantiated.

Specified by:

create in class JImplementationRepository

Parameters:

item - a int item associated with a concrete implementation

Returns:

the implementation desgined by the specified int item

Throws:

java.lang.IllegalArgumentException - if the specified int item is unknown by this repository

createPrimitiveClass

public JClass createPrimitiveClass(java.lang.String descriptor)
                            throws java.lang.IllegalArgumentException

Specified by:

createPrimitiveClass in class JImplementationRepository

Parameters:

descriptor - a primitive class descriptor

Returns:

a JClass object representing a primitive class

Throws:

java.lang.IllegalArgumentException - if the specified descriptor is not a descriptor for a primitive class or unknown by this repository
