Method Detail

getName

String getName()

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

getClassName

String getClassName()

Returns:

Fully qualified name of mapped class.

getParentType

DynamicType getParentType()

Returns:

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

getNumberOfProperties

int getNumberOfProperties()

The current number of properties.

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

getPropertiesNames

List<String> getPropertiesNames()

The current names of properties.

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

containsProperty

boolean containsProperty(String propertyName)

getPropertyIndex

int getPropertyIndex(String propertyName)

getJavaClass

Class<? extends DynamicEntity> getJavaClass()

newDynamicEntity

DynamicEntity newDynamicEntity()

getPropertyType

Class<?> getPropertyType(int propertyIndex)

getPropertyType

Class<?> getPropertyType(String propertyName)

getDescriptor

ClassDescriptor getDescriptor()

Returns:

the underlying ClassDescriptor for the mapped type
