columnTypes()

const type_info *const * openm::EntityAttrRowAdapter::columnTypes ( void  ) const

inlinevirtual

array[rowSize] of type_info for each column, used to convert from db-type to target type

Implements openm::IRowAdapter.

createRow()

IRowBase * openm::EntityAttrRowAdapter::createRow ( void  ) const

inlinevirtual

create new row (tuple, struct or array) initialized with default field values

Implements openm::IRowAdapter.

set()

void openm::EntityAttrRowAdapter::set ( IRowBase *  i_row, int  i_column, const void *  i_value  ) const

inlinevirtual

field value setter: i_row[i_column] = *i_value

Parameters

[in]	i_row	new row created by createRow()
[in]	i_column	zero-based column index
[in]	i_value	db-field value, casted to the target column type

this method called for each row by data library select() methods to set field values.
this method called only if db-field value NOT IS NULL.

Implements openm::IRowAdapter.

size()

int openm::EntityAttrRowAdapter::size ( void  ) const

inlinevirtual

return row size: number of columns

Implements openm::IRowAdapter.
