getDefaultOrderBy

public String getDefaultOrderBy()

Description copied from interface: IdBinder

Return the default order by that may need to be used if the query includes a many property.

Specified by:

public String getAssocOneIdExpr(String prefix,
                       String operator)

Description copied from interface: IdBinder

Build a string of the logical expressions.

Typically used to build a id = ? string.

Specified by:

getAssocIdInExpr

public String getAssocIdInExpr(String prefix)

Description copied from interface: IdBinder

Return the logical id in expression taking into account embedded id's.

Specified by:

getAssocIdInExpr in interface IdBinder

public void addIdInBindValue(SpiExpressionRequest request,
                    Object value)

Specified by:

addIdInBindValue in interface IdBinder

getIdInValueExprDelete

public String getIdInValueExprDelete(int size)

Description copied from interface: IdBinder

Same as getIdInValueExpr but for delete by id.

getIdValues

public Object[] getIdValues(Object bean)

Description copied from interface: IdBinder

Return the id values for a given bean.

Specified by:

getIdValues in interface IdBinder

getBindValues

public Object[] getBindValues(Object idValue)

Description copied from interface: IdBinder

Return the values as an array of scalar bindable values.

For concatenated keys that use an Embedded bean or multiple id properties this determines the field values are returns them as an Object array.

Added primarily for Query.addWhere().add(Expr.idEq()) support.

Specified by:

public void bindId(DefaultSqlUpdate sqlUpdate,
          Object value)

Description copied from interface: IdBinder

Bind the id value to a SqlUpdate statement.

Specified by:

appendSelect in interface IdBinder

convertSetId

public Object convertSetId(Object idValue,
                  Object bean)

Description copied from interface: IdBinder

Cast or convert the Id value if necessary and optionally set it.

The Id value is not assumed to be the correct type so it is converted to the correct type. Typically this is because we could get a Integer, Long or BigDecimal depending on the JDBC driver and situation.

If the bean is not null, then the value is set to the bean.
