All Known Implementing Classes:

public interface Bindable

Item held by Meta objects used to generate and bind bean insert update and delete statements.

An implementation is expected to be immutable and thread safe.

The design is to take a bean structure with embedded and associated objects etc and flatten that into lists of Bindable objects. These are put into InsertMeta UpdateMeta and DeleteMeta objects to support the generation of DML and binding of statements in a fast and painless manor.

Method Summary

Methods

Modifier and Type	Method and Description
void	addChanged(PersistRequestBean<?> request, List<Bindable> list) For Updates including only changed properties add the Bindable to the list if it should be included in the 'update set'.
void	dmlAppend(GenerateDmlRequest request, boolean checkIncludes) append sql to the buffer with prefix and suffix options.
void	dmlBind(BindableRequest request, boolean checkIncludes, Object bean) Bind given the request and bean.
void	dmlBindWhere(BindableRequest request, boolean checkIncludes, Object bean)
void	dmlInsert(GenerateDmlRequest request, boolean checkIncludes) append sql to the buffer with prefix and suffix options.
void	dmlWhere(GenerateDmlRequest request, boolean checkIncludes, Object bean) For WHERE clauses append sql to the buffer with prefix and suffix options.

Method Detail

addChanged

void addChanged(PersistRequestBean<?> request,
              List<Bindable> list)

For Updates including only changed properties add the Bindable to the list if it should be included in the 'update set'.

dmlInsert

void dmlInsert(GenerateDmlRequest request,
             boolean checkIncludes)

append sql to the buffer with prefix and suffix options.

dmlAppend

void dmlAppend(GenerateDmlRequest request,
             boolean checkIncludes)

append sql to the buffer with prefix and suffix options.

dmlWhere

void dmlWhere(GenerateDmlRequest request,
            boolean checkIncludes,
            Object bean)

For WHERE clauses append sql to the buffer with prefix and suffix options. These need to take into account binding of null values.

dmlBind

void dmlBind(BindableRequest request,
           boolean checkIncludes,
           Object bean)
             throws SQLException

Bind given the request and bean. The bean could be the oldValues bean when binding a update or delete where clause with ALL concurrency mode.

Throws:

SQLException

dmlBindWhere

void dmlBindWhere(BindableRequest request,
                boolean checkIncludes,
                Object bean)
                  throws SQLException

Throws:

SQLException
