- public class DataBlkFloat
- extends DataBlk
This is an implementation of the DataBlk interface for
32 bit floating point data (float).
The methods in this class are declared final, so that they can
be inlined by inlining compilers.

data
public float[] data
- The array where the data is stored
DataBlkFloat
public DataBlkFloat()
- Creates a DataBlkFloat with 0 dimensions and no data array
(i.e. data is null).
DataBlkFloat
public DataBlkFloat(int ulx,
int uly,
int w,
int h)
- Creates a DataBlkFloat with the specified dimensions and
position. The data array is initialized to an array of size
w*h.
- Parameters:
ulx
- The horizontal coordinate of the upper-left corner
of the blockuly
- The vertical coordinate of the upper-left corner
of the blockw
- The width of the block (in pixels)h
- The height of the block (in pixels)
DataBlkFloat
public DataBlkFloat(DataBlkFloat src)
- Copy constructor.
Creates a DataBlkFloat which is the copy of the DataBlkFloat
given as paramter.
- Parameters:
DataBlkFloat
- the object to be copied.
getDataType
public final int getDataType()
- Returns the identifier of this data type, TYPE_FLOAT,
as defined in DataBlk.
- Overrides:
- getDataType in class DataBlk
- Returns:
- The type of data stored. Always
DataBlk.TYPE_FLOAT
- See Also:
DataBlk.TYPE_FLOAT
getData
public final java.lang.Object getData()
- Returns the array containing the data, or null if there is no
data array. The returned array is a float array.
- Overrides:
- getData in class DataBlk
- Returns:
- The array of data (a float[]) or null if there is no
data.
getDataFloat
public final float[] getDataFloat()
- Returns the array containing the data, or null if there is no
data array.
- Returns:
- The array of data or null if there is no data.
setData
public final void setData(java.lang.Object arr)
- Sets the data array to the specified one. The provided array
must be a float array, otherwise a ClassCastException is
thrown. The size of the array is not checked for consistency
with the block's dimensions.
- Overrides:
- setData in class DataBlk
- Parameters:
arr
- The data array to use. Must be a float array.
setDataFloat
public final void setDataFloat(float[] arr)
- Sets the data array to the specified one. The size of the array
is not checked for consistency with the block's dimensions.
- Parameters:
arr
- The data array to use.
