protected QedeqBoFactory(ModuleAddress globalContext)

Constructor.

Parameters:

globalContext - Module location information.

Method Detail

createQedeq

public static DefaultQedeqBo createQedeq(ModuleAddress globalContext,
                                         Qedeq original)
                                  throws ModuleDataException

Create DefaultQedeqBo out of an Qedeq instance. During that procedure some basic checking is done. E.g. the uniqueness of entries is tested. The resulting business object has no references to the original Qedeq instance.

During the creation process the caller must assert that no modifications are made to the Qedeq instance including its referenced objects.

Parameters:

globalContext - Module location information.

original - Basic QEDEQ module object.

Returns:

Filled QEDEQ business object. Is equal to the parameter qedeq.

Throws:

ModuleDataException - Invalid data found.

create

protected final DefaultQedeqBo create(Qedeq original)
                               throws IllegalModuleDataException

Create DefaultQedeqBo out of an Qedeq instance. During that procedure some basic checking is done. E.g. the uniqueness of entries is tested. The resulting business object has no references to the original Qedeq instance.

During the creation process the caller must assert that no modifications are made to the Qedeq instance including its referenced objects.

Parameters:

original - Basic QEDEQ module object.

Returns:

Filled header business object. Is equal to the parameter header.

Throws:

IllegalModuleDataException - Basic semantic error occurred.

setLocationWithinModule

protected void setLocationWithinModule(String locationWithinModule)

Set location information where are we within the original module.

Parameters:

locationWithinModule - Location within module.

getCurrentContext

protected final ModuleContext getCurrentContext()

Get current context within original.

Returns:

Current context.

getQedeqOriginal

protected final Qedeq getQedeqOriginal()

Get original QEDEQ module.

Returns:

Original QEDEQ module.

getQedeqCreated

protected final QedeqBo getQedeqCreated()

Get currently created QEDEQ module.

Returns:

Currently created QEDEQ module.
