Method Detail

fields

List<Property> fields()

Return list of properties on the domain model managed by this repository.

Returns:

list of Property

all

Query<T> all()

Get the Query instance of the managed domain class.

Returns:

instance of Query

create

T create(Map<String,Object> values)

Create a new instance of the domain model with the given default values.

Parameters:

values - the default values

Returns:

an instance of the domain model managed by this repository

copy

T copy(T entity,
       boolean deep)

Create a duplicate copy of the given entity.

In case of deep copy, one-to-many records are duplicated. Otherwise, one-to-many records will be skipped.

Parameters:

entity - the entity bean to copy

deep - whether to create a deep copy

Returns:

a copy of the given entity

find

T find(Long id)

Find by primary key.

Parameters:

id - the record id

Returns:

a domain object found by the given id, null otherwise

findByIds

List<T> findByIds(List<Long> ids)

Find multiple entities by their primary key.

Parameters:

ids - The ids to load

Returns:

list of all the matched records

save

T save(T entity)

Save the given entity.

Depending on the implementation, it may return same entity or a copy of it. For example JPA implementation may return a copy if the given entity can't be managed.

Parameters:

entity - the entity object to save

Returns:

an instance of the entity with saved state

remove

void remove(T entity)

Remove the given entity.

Parameters:

entity - the entity object

refresh

void refresh(T entity)

Refresh the state of the instance from the database, overwriting changes made to the entity, if any.

Parameters:

entity - the entity object to refresh

flush

void flush()

Synchronize the persistence context to the underlying database.

                                  Map<String,Object> context)

Validate the given json map before persisting.

This method is called before the json map is converted to model object.

Parameters:

json - the json map to validate

context - the context

Returns:

validated json map

populate

Map<String,Object> populate(Map<String,Object> json,
                                  Map<String,Object> context)
