Class ChannelDataInput.FloatsReader

java.lang.Object
org.apache.sis.internal.storage.io.ChannelDataInput.ArrayReader
org.apache.sis.internal.storage.io.ChannelDataInput.FloatsReader
All Implemented Interfaces:
DataTransfer
Enclosing class:
ChannelDataInput
final class ChannelDataInput.FloatsReader extends ChannelDataInput.ArrayReader
Reads float values from the enclosing stream and stores them into the given destination array.

  • Field Details

    • view

      private FloatBuffer view
      A view over the enclosing byte buffer.

    • dest

      private float[] dest
      The array where to store the values.

  • Constructor Details

    • FloatsReader

      FloatsReader(FloatBuffer source)

    • FloatsReader

      FloatsReader(float[] dest)

  • Method Details

    • dataSizeShift

      public int dataSizeShift()
      Description copied from interface: DataTransfer
      Returns the size of the Java primitive type which is the element of the array. The size is expressed as the number of bits to shift: java dataSize = 1 << dataSizeShift;

    • dataArray

      public Object dataArray()
      Description copied from interface: DataTransfer
      Returns the data as a char[], short[], int[], long[], float[] or double[] array. This is either the array given in argument to the subclass constructor, or the array created by DataTransfer.createDataArray(int).

    • dataArrayAsBuffer

      public Buffer dataArrayAsBuffer()
      Description copied from interface: DataTransfer
      Returns DataTransfer.dataArray() wrapped in a buffer.

    • view

      public Buffer view()
      Description copied from interface: DataTransfer
      Returns the view created by the last call to DataTransfer.createView(), or null if none.

    • createView

      public Buffer createView()
      Description copied from interface: DataTransfer
      Creates a new buffer of the type required by the array to fill. This method is guaranteed to be invoked exactly once, after the ChannelData.buffer contains enough data.

    • createDataArray

      public void createDataArray(int n)
      Description copied from interface: DataTransfer
      Creates a destination array of the given length.

    • transfer

      void transfer(int p, int n)
      Description copied from class: ChannelDataInput.ArrayReader
      Transfers the data from the buffer created by DataTransfer.createView() to array of primitive Java type known by the subclass. This method may be invoked an arbitrary number of time.
      Specified by:
      transfer in class ChannelDataInput.ArrayReader

    • setDest

      public void setDest(Object array)
      Description copied from interface: DataTransfer
      Sets the destination to the given data array, which may be null.
