Method Detail

getAllPropertyInfo

public PropertyList getAllPropertyInfo()

Description copied from interface: HasProperties

Returns a list giving static information about all properties exported by this object.

Specified by:

getAllPropertyInfo in interface HasProperties

Overrides:

getAllPropertyInfo in class NumericProbeBase

Returns:

static information for all exported properties

setExtendData

public void setExtendData(boolean extend)

Enables extension of data past the last knot point.

Parameters:

extend - true if data is to be extended past the last knot point

Returns true if data is to be extended past the last knot point

Returns:

true if data is extended

read

public void read(java.io.File file,
                 boolean setTimes)
          throws java.io.IOException

Reads the start and stop times, scale value, and data for this probe from an ascii file. The following information should be provided in order, separated by white space:

• start time (either seconds or nanoseconds, as described below). Ignored if setTimes is false.
• stop time (either seconds or nanoseconds, as described below) Ignored if setTimes is false.
• scale value (floating point number; nominal value is 1) Ignored if setTimes is false.
• interpolation order ("step", "linear", or "cubic")
• number of data values n at each knot point (an integer)
• either the knot point time step (floating point number, in seconds), OR the keyword "explicit", indicating that knot time values are to be given explicitly
• the knot point data, with each knot point specified by n numbers, preceeded (if explicit time has been specified) by the corresponding time value (in seconds).

The start and stop times can be indicated in either seconds or nanoseconds. The former is assumed if the value is a double with a decimal point. For example, the following input

 2.0 10.0 1.2
 linear 2 explicit
 0.0 2.0 2.0
 1.1 4.0 3.0
 3.0 0.0 1.0
 

specifies a probe with a start and stop time of 2 and 10 seconds, respectively, a scale value of 1.2, linear interpolation, 2 values at each knot point, and three knot points at times 0.0, 1.1, and 3.0. If knot time is given implicitly by a time setp, then time is assumed to start at 0. The following input

 2000000000 3000000000 2.5
 step 2 2.0
 2.0 2.0
 4.0 3.0
 0.0 1.0
 

specifies a probe with a start and stop time of 2 and 3 seconds, respectively, a scale value of 2.5, step interpolation, 2 values at each knot point, and three knot points with times of 0, 2.0, and 4.0 (given implicity by a step size of 2.0).

The character '#' is a comment character, causing all subsequent input up to the next new line to be ignored.

Overrides:

read in class NumericProbeBase

Parameters:

file - File from which to read the probe information

setTimes - if true, sets the start time, stop time, and scale values to those indicated at the head of the file. If false, these values are ignored.

Throws:

java.io.IOException - if an I/O or format error occurred.

write

Parameters:

pw - writer which accepts the output

fmtStr - printf-style format string (if set to null then "%g" will be assumed, which will produce full precision output).

Throws:

java.io.IOException - if an I/O error occurs.

Applies the current numeric data of this probe, as input in the argument vec, and uses it to update the simulation for either the current absolute time t or probe relative time trel. The size of vec will equal the vector size of the probe (as returned by NumericProbeBase.getVsize(). Probe relative time is determined from the probe's start time and scale factor using

 trel = (t - startTime)/scale
