DataBlk Class Members

In This Topic

The following tables list the members exposed by DataBlk.

Public Fields

	Name	Description
	h	The height of the block, in pixels.
	offset	The offset in the array of the top-left coefficient
	progressive	The progressive attribute (`false` by default)
	scanw	The width of the scanlines used to store the data in the array
	TYPE_BYTE	The identifier for the `byte` data type, as signed 8 bits.
	TYPE_FLOAT	The identifier for the `float` data type
	TYPE_INT	The identifier for the `int` data type, as signed 32 bits.
	TYPE_SHORT	The identifier for the `short` data type, as signed 16 bits.
	ulx	The horizontal coordinate (in pixels) of the upper-left corner of the block of data. This is relative to the component of the image from where this block was filled or is to be filled.
	uly	The vertical coordinate of the upper-left corner of the block of data. This is relative to the component of the image from where this block was filled or is to be filled.
	w	The width of the block, in pixels.

Public Properties

Name Description

	Name	Description
	Data	Returns the array containing the data, or null if there is no data. The returned array is of the type returned by `getDataType()` (e.g., for `TYPE_INT`, it is a `int[]`). Each implementing class should provide a type specific equivalent method (e.g., `getDataInt()` in `DataBlkInt`) which returns an array of the correct type explicetely and not through an `Object`. Sets the data array to the specified one. The type of the specified data array must match the one returned by `getDataType()` (e.g., for `TYPE_INT`, it should be a `int[]`). If the wrong type of array is given a `ClassCastException` will be thrown. The size of the array is not necessarily checked for consistency with `w` and `h` or any other fields. Each implementing class should provide a type specific equivalent method (e.g., `setDataInt()` in `DataBlkInt`) which takes an array of the correct type explicetely and not through an `Object`.
	DataType	Returns the data type of the `DataBlk` object, as defined in this class.

Data

Returns the array containing the data, or null if there is no data. The returned array is of the type returned by getDataType() (e.g., for TYPE_INT, it is a int[]).

Each implementing class should provide a type specific equivalent method (e.g., getDataInt() in DataBlkInt) which returns an array of the correct type explicetely and not through an Object.

Sets the data array to the specified one. The type of the specified data array must match the one returned by getDataType() (e.g., for TYPE_INT, it should be a int[]). If the wrong type of array is given a ClassCastException will be thrown.

The size of the array is not necessarily checked for consistency with w and h or any other fields.

Each implementing class should provide a type specific equivalent method (e.g., setDataInt() in DataBlkInt) which takes an array of the correct type explicetely and not through an Object.

DataType Returns the data type of the DataBlk object, as defined in this class.

Public Methods

	Name	Description
	getSize	Returns the size in bits, given the data type. The data type must be one defined in this class. An `IllegalArgumentException` is thrown if `type` is not defined in this class.
	ToString	Returns a string of informations about the DataBlk
