void chrono::ChFunction_Recorder::Extimate_x_range ( double &  xmin,
double &  xmax 
) [virtual]

These functions can be used to implement automatic zooming on the most representative range of function (if GUI is implemented)

Reimplemented from chrono::ChFunction.

int chrono::ChFunction_Recorder::Get_Type ( ) [virtual]

Each class inherited from the ChFunction class must return an unique integer identifier with the virtual function Get_type(). This is useful for fast run-time downcasting etc.

Reimplemented from chrono::ChFunction.

double chrono::ChFunction_Recorder::Get_y ( double  x) [virtual]

Returns the y value of the function, at position x. (For this base class, it will be a constant value y=C).

Implements chrono::ChFunction.

double chrono::ChFunction_Recorder::Get_y_dx ( double  x) [virtual]

Returns the dy/dx derivative of the function, at position x. Note that inherited classes may also avoid overriding this method, because this base method already provide a general-purpose numerical differentiation to get dy/dx only from the Get_y() function. (however, if the analytical derivative is known, it may better to implement a custom method).

Reimplemented from chrono::ChFunction.

double chrono::ChFunction_Recorder::Get_y_dxdx ( double  x) [virtual]

Returns the ddy/dxdx double derivative of the function, at position x. Note that inherited classes may also avoid overriding this method, because this base method already provide a general-purpose numerical differentiation to get ddy/dxdx only from the Get_y() function. (however, if the analytical derivative is known, it may be better to implement a custom method).

Reimplemented from chrono::ChFunction.

void chrono::ChFunction_Recorder::StreamIN ( ChStreamInBinary mstream) [virtual]

Method to allow deserializing a persistent binary archive (ex: a file) into transient data.

Reimplemented from chrono::ChFunction.

void chrono::ChFunction_Recorder::StreamOUT ( ChStreamOutAscii mstream) [virtual]

Method to allow serialization of transient data in ascii, as a readable item, for example "chrono::GetLog() << myobject;"

Reimplemented from chrono::ChFunction.

void chrono::ChFunction_Recorder::StreamOUT ( ChStreamOutBinary mstream) [virtual]

Method to allow serializing transient data into a persistent binary archive (ex: a file).

Reimplemented from chrono::ChFunction.
