Constructor Detail

DynamicTypeImpl

public DynamicTypeImpl(ClassDescriptor descriptor,
                       DynamicType parentType)

Creation of an EntityTypeImpl for an existing Descriptor with mappings.

Parameters:

descriptor -

Method Detail

clone

public Object clone()

Overrides:

clone in class 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 List<DatabaseMapping> getMappings()

getName

public 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 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 Set<DatabaseMapping> getMappingsRequiringInitialization()

isInitialized

public boolean isInitialized()

containsProperty

public boolean containsProperty(String propertyName)

Specified by:

containsProperty in interface DynamicType

getJavaClass

public Class<? extends DynamicEntity> getJavaClass()

Specified by:

getJavaClass in interface DynamicType

getMapping

public DatabaseMapping getMapping(String propertyName)

getPropertiesNames

public List<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 Class<?> getPropertyType(String propertyName)

Specified by:

getPropertyType in interface DynamicType

newDynamicEntity

public DynamicEntity newDynamicEntity()

Specified by:

newDynamicEntity in interface DynamicType

checkSet

public void checkSet(String propertyName,
                     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(String propertyName)

Specified by:

getPropertyIndex in interface DynamicType

getPropertyType

public Class<?> getPropertyType(int propertyIndex)

Specified by:

getPropertyType in interface DynamicType

toString

public String toString()

Overrides:

toString in class Object
