Detailed Description

Class that allows modification of a float parameter in a template.

Constructor & Destructor Documentation

CSLFloatProxy	(	CdotXSITemplate *	in_pTemplate,
		SI_Int	in_nIndex,
		SI_Float	in_fThreshold = `SI_EPSILON`
	)

Constructor. Connects to a parameter in the parent template

Parameters:

	in_pTemplate	Pointer to the parent template
	in_Index	Index of the parameter in the template
	in_fThreshold	Tolerance value used to determine equality between two floats.

Member Function Documentation

CSLFloatProxy& operator= ( const CSLFloatProxy & in_Value )

Assignment operator. Assigns in_Value to the parameter referred by this proxy.

Parameters:

in_Value

The new value

Returns:: Reference to the current object.

CSLFloatProxy& operator= ( const SI_Float & in_Value )

Assignment operator. Assigns in_Value to the parameter referred by this proxy.

Parameters:

in_Value

The new value

Returns:: Reference to the current object.

SI_Bool operator== ( const CSLFloatProxy & in_ToCompare )

Comparison operator. Compares in_ToCompare with the value of the parameter referred by this proxy.

Parameters:

in_ToCompare

The instance to compare values with

Returns:: Whether or not the referred parameter and in_ToCompare are equal

Note:: Comparison is performed with a threshold value. You can perform exact comparison by setting the Threshold value to zero.

See also:: CSLFloatProxy::Threshold
CSLFloatProxy::SetThreshold

SI_Bool operator== ( const SI_Float & in_ToCompare )

Comparison operator. Compares in_ToCompare with the value of the parameter referred by this proxy.

Parameters:

in_ToCompare

The instance to compare values with

Returns:: Whether or not the referred parameter and in_ToCompare are equal

Note:: Comparison is performed with a threshold value. You can perform exact comparison by setting the Threshold value to zero.

See also:: CSLFloatProxy::Threshold
CSLFloatProxy::SetThreshold

SI_Float Threshold ( )

Returns the threshold value

Returns:: Tolerance value used to determine equality between two floats.

See also:: CSLFloatProxy::SetThreshold

void SetThreshold ( SI_Float in_fThreshold )

Sets the thresold value

Parameters:

in_fThreshold

Tolerance value used to determine equality between two floats. Example

        // no threshold, the values must be absolutely equal
        CSLFloatProxy l_fProxy( in_pTemplate, in_paramIdx, 0.0 );
        l_fProxy = 0.00501;

        if ( l_fProxy == 0.005F )
        {
            // We get here because abs(0.00501 - 0.005) > 0
        }

        // use a tolerance of 0.0001
        l_fProxy.SetThreshold( 0.0001F ); 

        if ( l_fProxy == 0.005F )
        {
            // We get here because abs(0.00501 - 0.005) <= 0.0001
        }
