Method Details

updateContainer

public void updateContainer(Object c)

Description copied from interface: NativeType

This method is used by an accessor (e.g., a Cursor) to request an update of the current data array.

As an example consider a CellCursor moving on a CellImg. The cursor maintains a NativeType which provides access to the image data. When the cursor moves from one cell to the next, the underlying data array of the NativeType must be switched to the data array of the new cell.

To achieve this, the CellCursor calls updateContainer() with itself as the argument. updateContainer() in turn will call NativeImg.update(Object) on it's container, passing along the reference to the cursor. In this example, the container would be a CellImg. While the NativeType does not know about the type of the cursor, the container does. CellImg knows that it is passed a CellCursor instance, which can be used to figure out the current cell and the underlying data array, which is then returned to the NativeType.

The idea behind this concept is maybe not obvious. The NativeType knows which basic type is used (float, int, byte, ...). However, it does not know how the data is stored (ArrayImg, CellImg, ...). This prevents the need for multiple implementations of NativeType .

Specified by:

updateContainer in interface NativeType<ComplexDoubleType>

Parameters:

c - reference to an accessor which can be passed on to the container (which will know what to do with it).

index

public Index index()

Description copied from interface: NativeType

Get the (modifiable) index into the current data array. The returned instance will always be the same for the same Type.

Specified by:

index in interface NativeType<ComplexDoubleType>

duplicateTypeOnSameNativeImg

public ComplexDoubleType duplicateTypeOnSameNativeImg()

Description copied from interface: NativeType

Creates a new NativeType which stores in the same physical array. This is only used internally.

Specified by:

duplicateTypeOnSameNativeImg in interface NativeType<ComplexDoubleType>

Returns:

a new NativeType instance working on the same NativeImg

getNativeTypeFactory

public NativeTypeFactory<ComplexDoubleType, DoubleAccess> getNativeTypeFactory()

Specified by:

getNativeTypeFactory in interface NativeType<ComplexDoubleType>

getRealFloat

public float getRealFloat()

Specified by:

getRealFloat in interface ComplexType<ComplexDoubleType>

getRealDouble

public double getRealDouble()

Specified by:

getRealDouble in interface ComplexType<ComplexDoubleType>

getImaginaryFloat

public float getImaginaryFloat()

Specified by:

getImaginaryFloat in interface ComplexType<ComplexDoubleType>

getImaginaryDouble

public double getImaginaryDouble()

Specified by:

getImaginaryDouble in interface ComplexType<ComplexDoubleType>

setReal

public void setReal(float r)

Specified by:

setReal in interface ComplexType<ComplexDoubleType>

setReal

public void setReal(double r)

Specified by:

setReal in interface ComplexType<ComplexDoubleType>

setImaginary

public void setImaginary(float i)

Specified by:

setImaginary in interface ComplexType<ComplexDoubleType>

setImaginary

public void setImaginary(double i)

Specified by:

setImaginary in interface ComplexType<ComplexDoubleType>

set

public void set(double r,
 double i)

set

public void set(ComplexDoubleType c)

Description copied from interface: Type

Sets the value of another Type.

Specified by:

set in interface Type<ComplexDoubleType>

Overrides:

set in class AbstractComplexType<ComplexDoubleType>

Parameters:

c - the new value

createVariable

public ComplexDoubleType createVariable()

Description copied from interface: Type

Creates a new Type variable which can only store one value.

Specified by:

createVariable in interface Type<ComplexDoubleType>

Returns:

a new Type variable

copy

public ComplexDoubleType copy()

Description copied from interface: Type

Creates a new Type variable that has the value of this Type

Specified by:

copy in interface Type<ComplexDoubleType>

Returns:

a new Type variable

getEntitiesPerPixel

public Fraction getEntitiesPerPixel()

Description copied from interface: NativeType

Get the number of entities in the storage array required to store one pixel value. A pixel value may be spread over several or less than one entity. For example, a complex number may require 2 entries of a float[] array to store one pixel. Or a 12-bit type might need 12/64th entries of a long[] array.

Specified by:

getEntitiesPerPixel in interface NativeType<ComplexDoubleType>

Returns:

the number of storage type entities required to store one pixel value.
