Detailed Description

template<const size_t valueLen>
class openm::ValueFormatterBase< valueLen >

false boolean value as string

converter for value column (parameter, accumulator or expression value) to string

Constructor & Destructor Documentation

ValueFormatterBase() [1/2]

template<const size_t valueLen>

openm::ValueFormatterBase< valueLen >::ValueFormatterBase ( const type_info &  i_type, bool  i_isSqlFormat = false, const char *  i_doubleFormat = ""  )

inline

converter for value column into string.

Parameters

[in]	i_type	value type, use std::string type for VARCHAR values
[in]	i_isSqlFormat	if true then convert into SQL constant: 'quoted string values' and 1/0 for boolean values
[in]	i_doubleFormat	if not null or empty then printf format for float and doubles, default: %.15g

ValueFormatterBase() [2/2]

template<const size_t valueLen>

openm::ValueFormatterBase< valueLen >::ValueFormatterBase ( const type_info &  i_type, const char *  i_doubleFormat = ""  )

inline

converter for value column into string.

Parameters

[in]	i_type	value type, use std::string type for VARCHAR values
[in]	i_doubleFormat	if not null or empty then printf format for float and doubles, default: %.15g

Member Function Documentation

formatValue()

template<const size_t valueLen>

const char * openm::ValueFormatterBase< valueLen >::formatValue ( const void *  i_value, bool  i_isNull = false  )

IValueFormatter interface implementation: convert value to string using snprintf.

Parameters

[in]	i_value	db-field value, casted to the target column type
[in]	i_isNull	if true then value is NULL and return is "null"

Returns

value converted to string, must be copied before next call.

Implements openm::IValueFormatter.
