Method Detail

detectEntityType

<T> PojoRawTypeIdentifier<? extends T> detectEntityType(T entity)

Detect the type of a given entity instance.

Type Parameters:

T - The type of the entity.

Parameters:

entity - An instance or proxy of T.

Returns:

The identifier of the instance's type, or of its delegate object's type if the instance is a proxy. May be null if the entity type is not known from this mapper, because it's neither indexed nor contained in an indexed type.

unproxy

Object unproxy(Object value)

Parameters:

value - the object to unproxy

Returns:

if value is a proxy, unwraps it, otherwise works as a pass-through function.

isIgnorableDataAccessThrowable

boolean isIgnorableDataAccessThrowable(Throwable throwable)

Parameters:

throwable - A Throwable thrown while accessing data on an entity: calling a getter, accessing a field, accessing the elements of a container, etc.

Returns:

true if this exception should be ignored and the data should be assumed empty (null, empty container, ...). false if this exception should be propagated. Note this is currently only taken into account while performing reindexing resolution.

simple

static PojoRuntimeIntrospector simple()

Returns:

A simple PojoRuntimeIntrospector that relies on the object's class to return entity types, and assumes objects are not proxyfied.
