Method Details

clear

public void clear(int start,
 int count)

Description copied from interface: Memory

Clear the specified number of frames/images/spectra starting with specified frame/image/spectrum number.

Specified by:

clear in interface Memory

Overrides:

clear in class Gdhist

Parameters:

start - is the starting frame/image/spectrum number (1st = 0)

count - is the number of frames/images/spectra to clear

clear

public void clear(int x,
 int y,
 int t,
 int dx,
 int dy,
 int dt)

Description copied from interface: Memory

Clear the specified block of memory. The parameters give the ability to clear a 3D block of memory.

Specified by:

clear in interface Memory

Overrides:

clear in class Gdhist

Parameters:

x - is the start address for the offset in the x dimension

y - is the start address for the offset in the y dimension

t - is the start address for the offset in the z or t dimension

dx - is the address count in the x dimension

dy - is the address count in the y dimension

dt - is the address count in the z or t dimension

setDimension

public void setDimension(int[] d)
                  throws DeviceException

Description copied from interface: Memory

Set the size of the memory system.

Specified by:

setDimension in interface Memory

Overrides:

setDimension in class Gdhist

Parameters:

d - is the

Throws:

DeviceException

getMemorySize

public int getMemorySize()
                  throws DeviceException

Description copied from interface: Memory

Get the physical memory size

Specified by:

getMemorySize in interface Memory

Overrides:

getMemorySize in class Gdhist

Returns:

the physical memory size expressed in words.

Throws:

DeviceException

getSupportedDimensions

public int[] getSupportedDimensions()

Description copied from interface: Memory

If the detector supports multiple pixel settings, this will return an array of possible values. Null otherwise. Assumes the detector is 2D with identical axes.

Specified by:

getSupportedDimensions in interface Memory

Overrides:

getSupportedDimensions in class Gdhist

Returns:

a collection of supported Dimensions
