Detailed Description

OSCILLOSCOPE FUNCTION y = interpolation of array of (x,y) data, where (x,y) points must be inserted one after the other, strictly with a fixed dx interval. After a maximum amount of recordable points is reached, the firsts are deleted. Note: differently from ChFunction_Recorder, this 'basic' function does not allow not-uniform dx spacing between points, but may be faster and simplier to use in many cases.

Member Function Documentation

int chrono::ChFunction_Oscilloscope::AddLastPoint	(	double	mx,
		double	my
	)

Add a point at the head (right side of point array). Note that it is user's responsability to add points which are spaced uniformily (by dx) on the X axis! No checks are done on the correctness of the dx spacing, except that if you enter a point whose mx is less than the mx of the one you previously entered, the array is cleared.

void chrono::ChFunction_Oscilloscope::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_Oscilloscope::Get_max_amount

(

)

Get the maximum amount of points which can be entered (after this, the first one will be deleted, as in a FIFO)

int chrono::ChFunction_Oscilloscope::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_Oscilloscope::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.

void chrono::ChFunction_Oscilloscope::Set_max_amount

(

int

mnum

)

Set the maximum amount of points which can be entered (after this, the first one will be deleted, as in a FIFO)

void chrono::ChFunction_Oscilloscope::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_Oscilloscope::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_Oscilloscope::StreamOUT

(

ChStreamOutBinary &

mstream

)

[virtual]

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

Reimplemented from chrono::ChFunction.
