Method Summary

void	addIdEqualsToQuery(Parameters parameters, Object id, String prefix, boolean equals) Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix, is equal to the given object.
void	addIdsEqualToQuery(Parameters parameters, String prefix1, IdMapper mapper2, String prefix2) Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix1, is equal to the id of the entity with alias prefix2 mapped by the second mapper (the second mapper must be for the same entity, but it can have, for example, prefixed properties).
void	addIdsEqualToQuery(Parameters parameters, String prefix1, String prefix2) Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix1, is equal to the id of the entity with alias prefix2 (the entity is the same).
void	addNamedIdEqualsToQuery(Parameters parameters, String prefix, boolean equals) Adds query statements, which contains named parameters, which express the property that the id of the entity with alias prefix, is equal to the given object.

Method Detail

addIdsEqualToQuery

public void addIdsEqualToQuery(Parameters parameters,
                               String prefix1,
                               String prefix2)

Description copied from interface: IdMapper

Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix1, is equal to the id of the entity with alias prefix2 (the entity is the same).

Specified by:

addIdsEqualToQuery in interface IdMapper

Parameters:

parameters - Parameters, to which to add the statements.

prefix1 - First alias of the entity + prefix to add to the properties.

prefix2 - Second alias of the entity + prefix to add to the properties.

addIdsEqualToQuery

public void addIdsEqualToQuery(Parameters parameters,
                               String prefix1,
                               IdMapper mapper2,
                               String prefix2)

Description copied from interface: IdMapper

Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix1, is equal to the id of the entity with alias prefix2 mapped by the second mapper (the second mapper must be for the same entity, but it can have, for example, prefixed properties).

Specified by:

addIdsEqualToQuery in interface IdMapper

Parameters:

parameters - Parameters, to which to add the statements.

prefix1 - First alias of the entity + prefix to add to the properties.

mapper2 - Second mapper for the same entity, which will be used to get properties for the right side of the equation.

prefix2 - Second alias of the entity + prefix to add to the properties.

addIdEqualsToQuery

public void addIdEqualsToQuery(Parameters parameters,
                               Object id,
                               String prefix,
                               boolean equals)

Description copied from interface: IdMapper

Adds query statements, which contains restrictions, which express the property that the id of the entity with alias prefix, is equal to the given object.

Specified by:

addIdEqualsToQuery in interface IdMapper

Parameters:

parameters - Parameters, to which to add the statements.

id - Value of id.

prefix - Prefix to add to the properties (may be null).

equals - Should this query express the "=" relation or the "<>" relation.

addNamedIdEqualsToQuery

public void addNamedIdEqualsToQuery(Parameters parameters,
                                    String prefix,
                                    boolean equals)

Description copied from interface: IdMapper

Adds query statements, which contains named parameters, which express the property that the id of the entity with alias prefix, is equal to the given object. It is the responsibility of the using method to read parameter values from the id and specify them on the final query object.

Specified by:

addNamedIdEqualsToQuery in interface IdMapper

Parameters:

parameters - Parameters, to which to add the statements.

prefix - Prefix to add to the properties (may be null).

equals - Should this query express the "=" relation or the "<>" relation.
