Constructor Detail

RasMArrayFloat

public RasMArrayFloat()

default constructor

RasMArrayFloat

public RasMArrayFloat(RasMInterval initDomain)

constructor for uninitialized MDD objects

Parameters:

initDomain - The initial Domain of the MArray

RasMArrayFloat

public RasMArrayFloat(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

RasMArrayFloat

public RasMArrayFloat(RasMInterval initDomain,
                      RasStorageLayout stl)

Constructor for uninitialized MDD objects with Storage Layout

Parameters:

initDomain - The initial Domain of the MArray

stl - The storage layout to be used

RasMArrayFloat

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

Constructor for uninitialized MDD objects with Storage Layout

Parameters:

initDomain - The initial Domain of the MArray

stl - The storage layout to be used

allocateData - control whether to allocate the data or not

RasMArrayFloat

public RasMArrayFloat(RasMArrayFloat obj)

copy constructor

Parameters:

obj - a copy of this object will be created

Method Detail

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[SIZE_OF_FLOAT] array. This kind of access to a cell is significantly slower than getFloat(), because each cell value has to be converted from float to a byte[SIZE_OF_FLOAT] 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

getFloat

public float getFloat(RasPoint point)
               throws RasDimensionMismatchException,
                      RasIndexOutOfBoundsException

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

Throws:

RasDimensionMismatchException

RasIndexOutOfBoundsException

getFloatArray

public float[] getFloatArray()

get the internal representation of the array

getArray

public byte[] getArray()

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

Overrides:

getArray in class RasGMArray

Returns:

the byte array representing this GMArray

setArray

public void setArray(float[] newData)

set the internal representation of the array
