Member Function Documentation

close()

int NidsFile::close

(

)

Closes the file

init()

readRadial()

int NidsFile::readRadial

(

NidsRadial &

radial

)

Gets the individual radial header. This specifies which radial data are coming from.

Parameters

radial

The radial header data

Returns

1=success, 0=no data, -1=error

readRun()

int NidsFile::readRun

(

NidsRun &

data

)

Gets the runlength encoded data.

Parameters

data	The run length data

Returns

1=success, 0=no data, -1=error

(

short &

val

)

Reads in a short integer value (2 bytes)

Return values

val	Buffer to put data

References readBytes().

Referenced by readRadial(), and readVector().

readVector()

int NidsFile::readVector

(

NidsVector &

vect

)

Gets a single vector which includes starting and ending locations.

Parameters

vect	The vector data

Returns

1=success, 0=no data, -1=error
