Constructor Details

RasMArrayDouble

public RasMArrayDouble()

default constructor

RasMArrayDouble

public RasMArrayDouble(RasMInterval initDomain)

constructor for uninitialized MDD objects

Parameters:

initDomain - The initial Domain of the MArray

RasMArrayDouble

public RasMArrayDouble(RasMInterval initDomain,
 boolean allocateData)

constructor for uninitialized MDD objects

Parameters:

initDomain - The initial Domain of the MArray

allocateData - control whether to allocate the data or not

RasMArrayDouble

public RasMArrayDouble(RasMInterval initDomain,
 RasStorageLayout stl)

Constructor for uninitialized MDD objects with Storage Layout

Parameters:

initDomain - The initial Domain of the MArray

RasStorageLayout - The storage layout to be used

RasMArrayDouble

public RasMArrayDouble(RasMInterval initDomain,
 RasStorageLayout stl,
 boolean allocateData)

Constructor for uninitialized MDD objects with Storage Layout

Parameters:

initDomain - The initial Domain of the MArray

allocateData - control whether to allocate the data or not

RasStorageLayout - The storage layout to be used

RasMArrayDouble

public RasMArrayDouble(RasMArrayDouble obj)

copy constructor

Parameters:

obj - a copy of this object will be created

Method Details

getCell

public byte[] getCell(RasPoint point)
               throws RasDimensionMismatchException,
RasIndexOutOfBoundsException

subscript operator for read access of a cell. The cell value is returned as a byte[4] array. This kind of access to a cell is significantly slower than getDouble(), because each cell value has to be converted from double to a byte[SIZE_OF_DOUBLE] array. The user has to take care that each Cell value is stored, before getting the next Cell.

Overrides:

getCell in class RasGMArray

Parameters:

point - the coordinates of the requested cell

Returns:

a byte array representing the value of the requested cell.

Throws:

RasDimensionMismatchException

RasIndexOutOfBoundsException

getDouble

public double getDouble(RasPoint point)
                 throws RasDimensionMismatchException,
RasIndexOutOfBoundsException

subscript operator for read access of a cell. The cell value is returned as an double. This access method is faster then getCell(), because no conversion from double to Byte[SIZE_OF_DOUBLE] has to be done.

Throws:

RasDimensionMismatchException

RasIndexOutOfBoundsException

getDoubleArray

public double[] getDoubleArray()

get the internal representation of the array

getArray

public byte[] getArray()

get the internal representation of the array in bytes, please use getDoubleArray()

Overrides:

getArray in class RasGMArray

Returns:

the byte array representing this GMArray

setArray

public void setArray(double[] newData)

set the internal representation of the array
