Class ClassDescriptorMap

java.lang.Object

org.apache.cayenne.reflect.ClassDescriptorMap

public class ClassDescriptorMap
extends Object

An object that holds class descriptors for mapped entities, compiling new descriptors on demand using an internal chain of descriptor factories. Note that the object is not synchronized internally, so it has to be prefilled with descriptors by the caller on initialization via calling 'getDescriptor' for all mapped entities.

Since:

3.0

Method Details

getResolver

public EntityResolver getResolver()

addFactory

public void addFactory(ClassDescriptorFactory factory)

Adds a factory to the descriptor factory chain.

removeFactory

public void removeFactory(ClassDescriptorFactory factory)

clearFactories

public void clearFactories()

clearDescriptors

public void clearDescriptors()

removeDescriptor

public void removeDescriptor(String entityName)

Removes cached descriptor if any for the given entity.

addDescriptor

public void addDescriptor(String entityName,
 ClassDescriptor descriptor)

Caches descriptor definition.

getDescriptor

public ClassDescriptor getDescriptor(String entityName)

createProxyDescriptor

protected ClassDescriptor createProxyDescriptor(String entityName)

Creates a descriptor wrapper that will compile the underlying descriptor on demand. Using proxy indirection is needed to compile relationships of descriptors to other descriptors that are not compiled yet.

createDescriptor

protected ClassDescriptor createDescriptor(String entityName)

Creates a new descriptor.
