| DataBlkFloat | | public class DataBlkFloat extends DataBlk (Code) | | 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.

| Field Summary | |
| public float[] | data
|
| Constructor Summary | |
| public | DataBlkFloat()
Creates a DataBlkFloat with 0 dimensions and no data array
(i.e. | | public | DataBlkFloat(int ulx, int uly, int w, int h)
Creates a DataBlkFloat with the specified dimensions and
position. | | public | DataBlkFloat(DataBlkFloat src)
Copy constructor. |
| Method Summary | |
| final public Object | getData()
Returns the array containing the data, or null if there is no
data array. | | final public float[] | getDataFloat()
Returns the array containing the data, or null if there is no
data array. | | final public int | getDataType()
Returns the identifier of this data type, TYPE_FLOAT,
as defined in DataBlk.
The type of data stored. | | final public void | setData(Object arr)
Sets the data array to the specified one. | | final public void | setDataFloat(float[] arr)
Sets the data array to the specified one. | | public String | toString()
Returns a string of informations about the DataBlkInt. |
| data | | public float[] data(Code) | | The array where the data is stored
|
| DataBlkFloat | | public DataBlkFloat()(Code) | | 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)(Code) | | 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 cornerof the block
Parameters:
uly - The vertical coordinate of the upper-left cornerof the block
Parameters:
w - The width of the block (in pixels)
Parameters:
h - The height of the block (in pixels) |
| DataBlkFloat | | public DataBlkFloat(DataBlkFloat src)(Code) | | Copy constructor.
Creates a DataBlkFloat which is the copy of the DataBlkFloat
given as paramter.
Parameters:
DataBlkFloat - the object to be copied. |
| getData | | final public Object getData()(Code) | | Returns the array containing the data, or null if there is no
data array. The returned array is a float array.
The array of data (a float[]) or null if there is nodata. |
| getDataFloat | | final public float[] getDataFloat()(Code) | | Returns the array containing the data, or null if there is no
data array.
The array of data or null if there is no data. |
| getDataType | | final public int getDataType()(Code) | | Returns the identifier of this data type, TYPE_FLOAT,
as defined in DataBlk.
The type of data stored. AlwaysDataBlk.TYPE_FLOAT
See Also: DataBlk.TYPE_FLOAT |
| setData | | final public void setData(Object arr)(Code) | | 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.
Parameters:
arr - The data array to use. Must be a float array. |
| setDataFloat | | final public void setDataFloat(float[] arr)(Code) | | 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. |
| toString | | public String toString()(Code) | | Returns a string of informations about the DataBlkInt.
