org.eclipse.persistence.internal.dynamic.DynamicTypeImpl

All Implemented Interfaces:

java.lang.Cloneable, DynamicType

public class DynamicTypeImpl
extends java.lang.Object
implements DynamicType, java.lang.Cloneable

An EntityType provides a metadata facade into the EclipseLink object-relational metadata (descriptors & mappings) with specific knowledge of the entity types being dynamic.

Since:

EclipseLink 1.2

Field Detail

descriptor

protected ClassDescriptor descriptor

parentType

protected DynamicType parentType

dpm

protected DynamicPropertiesManager dpm

mappingsRequiringInitialization

protected java.util.Set<DatabaseMapping> mappingsRequiringInitialization

These properties require initialization when a new instance is created. This includes properties that are primitives as well as relationships requiring indirection ValueHolders or collections.

Constructor Detail

DynamicTypeImpl

protected DynamicTypeImpl()

DynamicTypeImpl

public DynamicTypeImpl(ClassDescriptor descriptor,
                       DynamicType parentType)

Creation of an EntityTypeImpl for an existing Descriptor with mappings.

Parameters:

descriptor -

Method Detail

clone

public java.lang.Object clone()

Overrides:

clone in class java.lang.Object

getDescriptor

public ClassDescriptor getDescriptor()

Specified by:

getDescriptor in interface DynamicType

Returns:

the underlying ClassDescriptor for the mapped type

setDescriptor

public void setDescriptor(ClassDescriptor descriptor)

getDynamicPropertiesManager

public DynamicPropertiesManager getDynamicPropertiesManager()

setDynamicPropertiesManager

public void setDynamicPropertiesManager(DynamicPropertiesManager dpm)

getParentType

public DynamicType getParentType()

Specified by:

getParentType in interface DynamicType

Returns:

The parent type or null if this type does not have a persistent superclass

getMappings

public java.util.List<DatabaseMapping> getMappings()

getName

public java.lang.String getName()

Description copied from interface: DynamicType

Return the entity type's name. This is the short name of the class or the ClassDescriptor.getAlias()

Specified by:

getName in interface DynamicType

See Also:

DynamicType.getName()

getClassName

public java.lang.String getClassName()

Specified by:

getClassName in interface DynamicType

Returns:

Fully qualified name of mapped class.

getNumberOfProperties

public int getNumberOfProperties()

Description copied from interface: DynamicType

The current number of properties.

Note: Some implementations support adding mapped attributes at runtime so it is best to avoid caching the result.

Specified by:

getNumberOfProperties in interface DynamicType

getMappingsRequiringInitialization

public java.util.Set<DatabaseMapping> getMappingsRequiringInitialization()

isInitialized

public boolean isInitialized()

containsProperty

public boolean containsProperty(java.lang.String propertyName)

Specified by:

containsProperty in interface DynamicType

getJavaClass

public java.lang.Class<? extends DynamicEntity> getJavaClass()

Specified by:

getJavaClass in interface DynamicType

getMapping

public DatabaseMapping getMapping(java.lang.String propertyName)

getPropertiesNames

public java.util.List<java.lang.String> getPropertiesNames()

Description copied from interface: DynamicType

The current names of properties.

Note: Some implementations support adding mapped attributes at runtime so it is best to avoid caching the result.

Specified by:

getPropertiesNames in interface DynamicType

getPropertyType

public java.lang.Class<?> getPropertyType(java.lang.String propertyName)

Specified by:

getPropertyType in interface DynamicType

newDynamicEntity

public DynamicEntity newDynamicEntity()

Specified by:

newDynamicEntity in interface DynamicType

checkSet

public void checkSet(java.lang.String propertyName,
                     java.lang.Object value)
              throws DynamicException

Ensure the value being set is supported by the mapping. If the mapping is direct/basic and the mapping's type is primitive ensure the non-primitive type is allowed.

Throws:

DynamicException

getPropertyIndex

public int getPropertyIndex(java.lang.String propertyName)

Specified by:

getPropertyIndex in interface DynamicType

getPropertyType

public java.lang.Class<?> getPropertyType(int propertyIndex)

Specified by:

getPropertyType in interface DynamicType

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
