Constructor Detail

PersistenceUnitsDescriptor

public PersistenceUnitsDescriptor()

Method Detail

getParent

public RootDeploymentDescriptor getParent()

setParent

public void setParent(RootDeploymentDescriptor parent)

getPuRoot

public java.lang.String getPuRoot()

setPuRoot

public void setPuRoot(java.lang.String puRoot)

getDefaultSpecVersion

public java.lang.String getDefaultSpecVersion()

Specified by:

getDefaultSpecVersion in class RootDeploymentDescriptor

Returns:

the default version of the deployment descriptor loaded by this descriptor

getModuleID

public java.lang.String getModuleID()

Specified by:

getModuleID in class RootDeploymentDescriptor

Returns:

the module ID for this module descriptor

getModuleType

public XModuleType getModuleType()

Specified by:

getModuleType in class RootDeploymentDescriptor

Returns:

the module type for this bundle descriptor

getClassLoader

public java.lang.ClassLoader getClassLoader()

Specified by:

getClassLoader in class RootDeploymentDescriptor

Returns:

the class loader associated with this module

isApplication

public boolean isApplication()

Specified by:

isApplication in class RootDeploymentDescriptor

Returns:

true if this module is an application object

addPersistenceUnitDescriptor

public void addPersistenceUnitDescriptor(PersistenceUnitDescriptor pud)

This method does not do any validation like checking for unique names of PersistenceUnits.

Parameters:

pud - the PersistenceUnitDescriptor to be added.

getPersistenceUnitDescriptors

public java.util.List<PersistenceUnitDescriptor> getPersistenceUnitDescriptors()

Returns:

an unmodifiable list.

getAbsolutePuRoot

public java.lang.String getAbsolutePuRoot()

This is a utility method which calculates the absolute path of the root of a PU. Absolute path is not the path with regards to root of file system. It is the path from the root of the Java EE application this persistence unit belongs to. Like getPuRoot() returned path always uses '/' as path separator.

Returns:

the absolute path of the root of this persistence unit

getPuRoot()

isEmpty

public boolean isEmpty()

Description copied from class: RootDeploymentDescriptor

Return true if this root deployment descriptor does not describe anything

Specified by:

isEmpty in class RootDeploymentDescriptor

Returns:

true if this root descriptor is empty
