Method Details

createClass

public GeneratedClass createClass(Class<?> baseClass,
 Node displayNodes,
 StrictMappingProperties strictMappingProperties)
                           throws javassist.NotFoundException,
javassist.CannotCompileException,
ClassNotFoundException

Creates a class, derived from the given base-class.

A class is dynamically generated, whenever a source or target has been downsized, and the given combination of base-class and nodes has not been registered before.

A class will also be generated when an object is mapped to a record.

Parameters:

baseClass - The class that will be used to generate a blueprint for the new class.

displayNodes - A wrapper for the fields that need to be present in the resulting class.

strictMappingProperties - Configuration regarding strict mapping.

Returns:

A GeneratedClass-object representing a CtClass and a Class.

Throws:

javassist.NotFoundException - May be thrown when Javassist creates a CtClass based on the name of the given base-class.

javassist.CannotCompileException - If Javassist cannot compile the CtClass to bytecode, a CannotCompileException will be thrown.

ClassNotFoundException

createClassDerivedFromRecord

public GeneratedClass createClassDerivedFromRecord(Class<? extends Record> clazz,
 Set<String> fieldNames)
                                            throws javassist.NotFoundException,
javassist.CannotCompileException

Creates a class specifically derived from a Record-class.

This method is used whenever a record is used as a source and the configuration allows for the use of converters.

Parameters:

clazz - The class that will serve as the baseclass for the dynamically generated class.

Returns:

A GeneratedClass based on the source class.

Throws:

javassist.NotFoundException - May be thrown when Javassist creates a CtClass, based on the name of the given base-class.

javassist.CannotCompileException - If Javassist cannot compile the CtClass to bytecode, a CannotCompileException is thrown.
