 TypeManager typeManager)

Method Details

find

public EntityQueryBuilder<Entity> find(String entityModel)

Description copied from interface: QueryBuilderFactory

Create an EntityQueryBuilder with the provided entity model as root

Specified by:

find in interface QueryBuilderFactory

Parameters:

entityModel - the target entity model

Returns:

the created EntityQueryBuilder

findKeys

public PrimaryKeyQueryBuilder findKeys(String entityModel)

Specified by:

findKeys in interface QueryBuilderFactory

select

public <T> PathQueryBuilder<T> select(Class<T> returnType,
 String entityModel,
 String... columns)

Description copied from interface: QueryBuilderFactory

Create a PathQueryBuilder with the provided entity model as root and the provided columns as selection

Specified by:

select in interface QueryBuilderFactory

Parameters:

returnType - the type the query returns, currently either Map or Object[]

entityModel - the target entity model

columns - the columns to select

Returns:

the created PathQueryBuilder

select

public <E> SinglePathQueryBuilder<E> select(Class<E> type,
 String entityModel,
 String column)

Description copied from interface: QueryBuilderFactory

Create a SinglePathQueryBuilder with the provided entity model as root and the single column as selection

Specified by:

select in interface QueryBuilderFactory

Type Parameters:

E - the return type, equal to the type of the selected column

Parameters:

type - the type of the selected column

entityModel - the target entity model

column - the selected column

Returns:

the created SinglePathQueryBuilder

resolve

public EntityQueryBuilder<Entity> resolve(EntityReference source,
 String relationPath)

Description copied from interface: QueryBuilderFactory

Create an EntityQueryBuilder that first resolves the given relation path and uses the target entity model of the given relation path as query root.

Specified by:

resolve in interface QueryBuilderFactory

Parameters:

source - the source entity

relationPath - the relation path, e.g. 'relAddress_user.relAddress'

Returns:

the created EntityQueryBuilder

resolve

public EntityQueryBuilder<Entity> resolve(EntityReference source,
 Path relationPath)

Specified by:

resolve in interface QueryBuilderFactory

count

public CountQueryBuilder count(Class<? extends Entity> entityClass)

Description copied from interface: QueryBuilderFactory

Create a new CountQueryBuilder which executes count queries.

Specified by:

count in interface QueryBuilderFactory

Parameters:

entityClass - the root entity

count

public CountQueryBuilder count(String modelName)

Description copied from interface: QueryBuilderFactory

Create a new CountQueryBuilder which executes count queries.

Specified by:

count in interface QueryBuilderFactory

Parameters:

modelName - the model name of the root entity

count

public CountQueryBuilder count(Class<? extends Entity> entityClass,
 Map<String,?> hints)

Description copied from interface: QueryBuilderFactory

Create a new CountQueryBuilder which executes count queries.

Specified by:

count in interface QueryBuilderFactory

Parameters:

entityClass - the root entity

hints - optional hints about the query (see QueryHints for available hints)

count

public CountQueryBuilder count(String modelName,
 Map<String,?> hints)

Description copied from interface: QueryBuilderFactory

Create a new CountQueryBuilder which executes count queries.

Specified by:

count in interface QueryBuilderFactory

Parameters:

modelName - the model name of the root entity

hints - optional hints about the query (see QueryHints for available hints)

evaluate

public boolean evaluate(Condition condition,
 Entity target,
 Map<String,Object> params)

Description copied from interface: QueryBuilderFactory

Evaluates the given `condition` against the given entity. Returns `true` if the entity would have been returned from a query formed by `condition`, `false` otherwise. The `params` map must contain all parameter values if those are used within the `condition`. Note that subqueries (like `EXISTS` and `COUNT`) and functions (like `fulltext` or `DISTANCE`) are currently *not* supported. `JdbcFunction`s (like `DISTANCE`) can't work anyways as they are directly translated to database calls.

Specified by:

evaluate in interface QueryBuilderFactory

asPredicate

public Predicate<Entity> asPredicate(Condition condition)

Description copied from interface: QueryBuilderFactory

Get a Predicate for the provided Condition. It can be used, for example to filter a list of previously loaded Entitys.

Specified by:

asPredicate in interface QueryBuilderFactory

Parameters:

condition - a Condition
