Detailed Description

Represents a float value.

Member Function Documentation

CValue* integra_api::CFloatValue::clone ( ) const

virtual

Creates copy of value.

Creates a CValue of same type and value, allocated on the heap with new

Implements integra_api::CValue.

void integra_api::CFloatValue::convert ( CValue &  conversion_target ) const

virtual

Converts value into another type.

Copies value into conversion_target, retaining as much information as possible when types differ

Implements integra_api::CValue.

float integra_api::CFloatValue::get_distance ( const CValue &  other ) const

virtual

Obtain an arbitrary measure of magnitude of different between values.

Expects types to be the same. For numeric types, distance is actually abs( difference ) For strings, distance is taken as the levenshtein_distance (http://en.wikipedia.org/wiki/Levenshtein_distance

Parameters

other

Value to compare

Returns

a distance value if values are of same type, or -1 if types differ

Implements integra_api::CValue.

bool integra_api::CFloatValue::is_equal ( const CValue &  other ) const

virtual

Compares values.

Parameters

other

Value to compare

Returns

true if values are of same type and equal value, otherwise false

Implements integra_api::CValue.

integra_api::CFloatValue::operator float ( ) const

virtual

Cast to a float.

See operator int() for further discussion of CValue's casting operators

Reimplemented from integra_api::CValue.

void integra_api::CFloatValue::set_from_string ( const string &  source )

virtual

Set value from string.

Note

when setting a numerical value, if conversion is not possible, the value is set to 0

Implements integra_api::CValue.
