Field Detail

DEFAULT

public static final MosaicImageReader.Spi DEFAULT

The default instance. There is no instance of this provider registered in the standard IIORegistry, because this provider is not strictly compliant with the Image I/O requirement (in particular, the Mosaic Image Reader does not accept ImageInputStream). This constant can be used as a replacement.

Constructor Detail

MosaicImageReader.Spi

public MosaicImageReader.Spi()

Creates a default provider. This constructor does not set the ImageReaderSpi.inputTypes field in order to delay loading of Tile and TileManager classes as much as possible.

Method Detail

getInputTypes

public Class<?>[] getInputTypes()

Returns the types of objects that may be used as arguments to the ImageReader.setInput(Object) method. This method initializes the ImageReaderSpi.inputTypes field when first needed.

The types that MosaicImageReader can accept are the types that TileManagerFactory.createFromObject(Object) can process.

Overrides:

getInputTypes in class ImageReaderSpi

Since:

3.18

canDecodeInput

public boolean canDecodeInput(Object source)
                       throws IOException

Returns true if the image reader can decode the given input. The default implementation returns true if the given object is an instance assignable to one of the types returned by the getInputTypes() implementation of this Spi class, and other type-specific restrictions are meet (e.g. Collection contains only instances of Tile, etc.).

Specified by:

canDecodeInput in class ImageReaderSpi

Throws:

IOException - If an I/O operation was required and failed.

createReaderInstance

public ImageReader createReaderInstance(Object extension)
                                 throws IOException

Returns a new MosaicImageReader.

Specified by:

createReaderInstance in class ImageReaderSpi

Throws:

IOException - If an I/O operation was required and failed.

getDescription

public String getDescription(Locale locale)

Returns a brief, human-readable description of this service provider.

Specified by:

getDescription in class IIOServiceProvider
