Class ComponentSampleModel

    java.lang.Object
      java.awt.image.SampleModel
          java.awt.image.ComponentSampleModel

Direct Known Subclasses:
  BandedSampleModel, PixelInterleavedSampleModel

    public class ComponentSampleModel

extends SampleModel

This class represents image data which is stored such that each sample of a pixel occupies one data element of the DataBuffer. It stores the N samples which make up a pixel in N separate data array elements. Different bands may be in different banks of the DataBuffer. Accessor methods are provided so that image data can be manipulated directly. This class can support different kinds of interleaving, e.g. band interleaving, scanline interleaving, and pixel interleaving. Pixel stride is the number of data array elements between two samples for the same band on the same scanline. Scanline stride is the number of data array elements between a given sample and the corresponding sample in the same column of the next scanline. Band offsets denote the number of data array elements from the first data array element of the bank of the DataBuffer holding each band to the first sample of the band. The bands are numbered from 0 to N-1. This class can represent image data for which each sample is an unsigned integral number which can be stored in 8, 16, or 32 bits (using `DataBuffer.TYPE_BYTE`, `DataBuffer.TYPE_USHORT`, or `DataBuffer.TYPE_INT`, respectively), data for which each sample is a signed integral number which can be stored in 16 bits (using `DataBuffer.TYPE_SHORT`), or data for which each sample is a signed float or double quantity (using `DataBuffer.TYPE_FLOAT` or `DataBuffer.TYPE_DOUBLE`, respectively). All samples of a given ComponentSampleModel are stored with the same precision. All strides and offsets must be non-negative. This class supports `TYPE_BYTE`, `TYPE_USHORT`, `TYPE_SHORT`, `TYPE_INT`, `TYPE_FLOAT`, `TYPE_DOUBLE`,

    `getNumDataElements` in class `SampleModel`
  Returns:
    the number of data elements needed to transfer a pixel with the `getDataElements` and `setDataElements` methods.
  See Also:
    `SampleModel.getNumDataElements()`, `SampleModel.getNumBands()`

### getDataElements

    public Object getDataElements(int x,
                                  int y,
                                  Object obj,
                                  DataBuffer data)

  Returns data for a single pixel in a primitive array of type `TransferType`. For a `ComponentSampleModel`, this is the same as the data type, and samples are returned one per array element. Generally, `obj` should be passed in as `null`, so that the `Object` is created automatically and is the right primitive data type.

  The following code illustrates transferring data for one pixel from `DataBuffer` `db1`, whose storage layout is described by `ComponentSampleModel` `csm1`, to `DataBuffer` `db2`, whose storage layout is described by `ComponentSampleModel` `csm2`. The transfer is usually more efficient than using `getPixel` and `setPixel`.

                   ComponentSampleModel csm1, csm2;
                   DataBufferInt db1, db2;
                   csm2.setDataElements(x, y,
                                  csm1.getDataElements(x, y, null, db1), db2);

  Using `getDataElements` and `setDataElements` to transfer between two `DataBuffer/SampleModel` pairs is legitimate if the `SampleModel` objects have the same number of bands, corresponding bands have the same number of bits per sample, and the `TransferType`s are the same.

  If `obj` is not `null`, it should be a primitive array of type `TransferType`. Otherwise, a `ClassCastException` is thrown. An `ArrayIndexOutOfBoundsException` might be thrown if the coordinates are not in bounds, or if `obj` is not `null` and is not large enough to hold the pixel data.

  Specified by:
    `getDataElements` in class `SampleModel`
  Parameters:
    `x, y` - the coordinates of the pixel location
    `obj` - if non-`null`, a primitive array in which to return the pixel data
    `data` - the `DataBuffer` containing the image data
  Returns:
    the data of the specified pixel
  Throws:
    `NullPointerException` - if data is null.
    `ArrayIndexOutOfBoundsException` - if the coordinates are not in bounds, or if obj is too small to hold the ouput.
  See Also:
    `setDataElements(int, int, Object, DataBuffer)`

                                  db2);

  Using `getDataElements` and `setDataElements` to transfer between two `DataBuffer/SampleModel` pairs is legitimate if the `SampleModel` objects have the same number of bands, corresponding bands have the same number of bits per sample, and the `TransferType`s are the same.

### equals

    public boolean equals(Object o)

  Description copied from class: `Object`
  Indicates whether some other object is "equal to" this one.

  The `equals` method implements an equivalence relation on non-null object references:

  - It is reflexive: for any non-null reference value `x`, `x.equals(x)` should return `true`.
  - It is symmetric: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
  - It is transitive: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
  - It is consistent: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
  - For any non-null reference value `x`, `x.equals(null)` should return `false`.

  The `equals` method for class `Object` implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values `x` and `y`, this method returns `true` if and only if `x` and `y` refer to the same object (`x == y` has the value `true`).

  Note that it is generally necessary to override the `hashCode` method whenever this method is overridden, so as to maintain the general contract for the `hashCode` method, which states that equal objects must have equal hash codes.

  Overrides:
    `equals` in class `Object`
  Parameters:
    `o` - the reference object with which to compare.
  Returns:
    `true` if this object is the same as the obj argument; `false` otherwise.
  See Also:
    `Object.hashCode()`, `Hashtable`

### hashCode

    public int hashCode()

  Description copied from class: `Object`
  Returns a hash code value for the object. This method is supported for the benefit of hashtables such as those provided by `java.util.Hashtable`.

  The general contract of `hashCode` is:

  - Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  - If two objects are equal according to the `equals(Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
  - It is not required that if two objects are unequal according to the `Object.equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hashtables.

  As much as is reasonably practical, the hashCode method defined by class `Object` does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the JavaTM programming language.)

  Overrides:
    `hashCode` in class `Object`
  Returns:
    a hash code value for this object.
  See Also:
    `Object.equals(java.lang.Object)`, `Hashtable`
