public interface FilteringDao<O extends Identifiable>
extends BaseDao<O>

Interface for filtering-capable DAO.

Filtering DAOs have the capability of using Filters and Sort abstractions for browsing entities. There are also extra conveniences for loading IDs loadIds(Filters, Sort) and counting entities count(Filters) without having to retrieve too much from the persistent storage.

This interface also provides introspection capabilities for enumerating and getting some meta information about filterable properties.

Method Details

getFilterableProperties

Set<String> getFilterableProperties()

List all properties availble for filtering.

getFilterablePropertyType

Class<?> getFilterablePropertyType(String propertyName)
                            throws IllegalArgumentException

Obtain the type of the given filterable property.

Throws:

IllegalArgumentException - if no such property exists, the cause will be a NoSuchFieldException

getFilterablePropertyDescription

@Nullable
String getFilterablePropertyDescription(String propertyName)
                                 throws IllegalArgumentException

Obtain a short description for a given filterable property.

Throws:

IllegalArgumentException - if no such property exists

getFilterablePropertyAllowedValues

@Nullable
List<Object> getFilterablePropertyAllowedValues(String property)
                                         throws IllegalArgumentException

Obtain a short list of allowed values for the given property, or null if unrestricted.

The returned values must be of the type outlined by getFilterablePropertyType(String), generally a list of String or Integer to denote possible values for an enumerated type.

Throws:

IllegalArgumentException

isFilterablePropertyUsingSubquery

boolean isFilterablePropertyUsingSubquery(String property)
                                   throws IllegalArgumentException

Indicate if the given property is using a subquery for filtering.

Throws:

IllegalArgumentException - if the property does not exist

isFilterablePropertyDeprecated

boolean isFilterablePropertyDeprecated(String property)
                                throws IllegalArgumentException

Indicate if the given property is deprecated.

Throws:

IllegalArgumentException - if the property does not exist

getFilter

Filter getFilter(String property,
 Filter.Operator operator,
 String value)
          throws IllegalArgumentException

Obtain an Filter for the entity this DAO is providing.

It is the responsibility of the DAO to infer the filter property type as well as the alias to use.

If the filter refers to a related entity (i.e. a BioAssay of an ExpressionExperiment), then the DAO should inject the corresponding DAO and delegate it the work of creating the filter.

In the frontend, that correspond to a FilterArg, but since the definition is not available here, we unpack its attributes.

Parameters:

property - property name in the entity use as a left-hand side of the operator

operator - an operator

value - the corresponding, unparsed value, to the right-hand side of the operator

Returns:

a filter filled with the object alias, property, inferred type, operator and parsed value

Throws:

IllegalArgumentException - if the property does not exist in FilteringDao, or if the operator cannot be applied, or if the value cannot apply to the property an operator see Filter.parse(String, String, Class, Filter.Operator, String, String) for more details

getFilter

Filter getFilter(String property,
 Filter.Operator operator,
 String value,
 SubqueryMode subqueryMode)

getFilter

Filter getFilter(String property,
 Filter.Operator operator,
 Collection<String> values)
          throws IllegalArgumentException

Similar to getFilter(String, Filter.Operator, String), but with a collection of values.

Throws:

IllegalArgumentException

getFilter

Filter getFilter(String property,
 Filter.Operator operator,
 Collection<String> values,
 SubqueryMode subqueryMode)

getFilter

<T> Filter getFilter(String property,
 Class<T> propertyType,
 Filter.Operator operator,
 T value)
              throws IllegalArgumentException

Obtain a Filter with an already parsed value.

Throws:

IllegalArgumentException

See Also:

• getFilter(String, Filter.Operator, String)

getFilter

<T> Filter getFilter(String property,
 Class<T> propertyType,
 Filter.Operator operator,
 Collection<T> values)
              throws IllegalArgumentException

Obtain a Filter with an already parsed collection of values.

Throws:

IllegalArgumentException

See Also:

• getFilter(String, Filter.Operator, Collection)

getSort

Sort getSort(String property,
 @Nullable
 Sort.Direction direction,
 Sort.NullMode nullMode)
      throws IllegalArgumentException

Obtain a Sort object for a property of the FilteringDao.

Parameters:

property - a property of FilteringDao to sort by

direction - a sorting direction, or null if the default direction applies

nullMode - behavior for null values when sorting

Returns:

a Sort object that can be used, for example, on FilteringVoEnabledDao.loadValueObjects(Filters, Sort, int, int)

Throws:

IllegalArgumentException - if no such field exists in FilteringDao

loadIds

List<Long> loadIds(@Nullable
 Filters filters,
 @Nullable
 Sort sort)

Load IDs of entities matching the given filters.

load

List<O> load(@Nullable
 Filters filters,
 @Nullable
 Sort sort)

Load entities matching the given filters.

load

Slice<O> load(@Nullable
 Filters filters,
 @Nullable
 Sort sort,
 int offset,
 int limit)

Load a slice of entities matching the given filters.

count

long count(@Nullable
 Filters filters)

Count VOs matching the given filters.
