Interface ReadOnlyPersistentAttribute

All Superinterfaces:

IAdaptable, JpaContextNode, JpaNode, JpaStructureNode, JptResourceTypeReference, Model, ReadOnlyAccessHolder

All Known Subinterfaces:

JavaPersistentAttribute, OrmPersistentAttribute, OrmReadOnlyPersistentAttribute, PersistentAttribute, PersistentAttribute2_0, ReadOnlyPersistentAttribute2_0

public interface ReadOnlyPersistentAttribute
extends JpaStructureNode, ReadOnlyAccessHolder

Read-only context persistent attribute (field or property).

Provisional API: This interface is part of an interim API that is still under development and expected to change significantly before reaching stability. It is available at this early stage to solicit feedback from pioneering adopters on the understanding that any code that uses this API will almost certainly be broken (repeatedly) as the API evolves.

Since:

... a while?

Method Detail

getName

String getName()

getMapping

AttributeMapping getMapping()

Return the attribute's mapping. This is never null (although, it may be a null mapping). Set the mapping via PersistentAttribute.setMappingKey(String).

getMappingKey

String getMappingKey()

Return the attribute's mapping key.

getDefaultMappingKey

String getDefaultMappingKey()

Return the key for the attribute's default mapping. This can be null (e.g. for specified orm.xml attributes).

See Also:

AttributeMapping.isDefault()

getOwningPersistentType

PersistentType getOwningPersistentType()

Return the persistent type that owns (declares) the attribute.

getOwningTypeMapping

TypeMapping getOwningTypeMapping()

Return the attribute's owning persistent type's mapping (as opposed to the attribute's target type's mapping).

getTypeName

String getTypeName()

Return the resolved, qualified name of the attribute's type (e.g. "java.util.Collection" or "byte[]"). Return null if the attribute's type can not be resolved. If the type is an array, this name will include the appropriate number of bracket pairs. This name will not include the type's generic type arguments (e.g. "java.util.Collection" will only return "java.util.Collection").

getTypeName

String getTypeName(PersistentType contextType)

Return the resolved, qualified name of the attribute's type (see getTypeName()) in the context of the given PersistentType. (In some cases, the attribute's type may be further constrained by a subclass of the persistent type that actually contains the attribute.) Return null if a type cannot be determined for this attribute in the given context.

getPrimaryKeyColumnName

String getPrimaryKeyColumnName()

If the attribute is mapped to a primary key column, return the column's name, otherwise return null.

isVirtual

boolean isVirtual()

Return whether the attribute has a textual representation in its underlying resource.

getJavaPersistentAttribute

JavaPersistentAttribute getJavaPersistentAttribute()
