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.

      public float[] data
      The array where the data is stored
  • Constructor Details

    • 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 block
      uly - The vertical coordinate of the upper-left corner of the block
      w - 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:
      src - the object to be copied.

    • getDataType

      public final int getDataType()
      Returns the identifier of this data type, TYPE_FLOAT, as defined in DataBlk.
      Specified by:
      getDataType in class DataBlk
      Returns:
      The type of data stored. Always DataBlk.TYPE_FLOAT

    • getData

      public final Object getData()
      Returns the array containing the data, or null if there is no data array. The returned array is a float array.
      Specified by:
      getData in class DataBlk
      Returns:
      The array of data (a float[]) or null if there is no data.
      See Also:
    • 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(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.
      Specified by:
      setData in class DataBlk
      Parameters:
      arr - The data array to use. Must be a float array.
      See Also:
    • 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.
    • toString

      public String toString()
      Returns a string of informations about the DataBlkInt.
      Overrides:
      toString in class DataBlk
      Returns:
      Block dimensions and progressiveness in a string
