Field Detail

USE_MULTITHREADING

public static final DefaultParameterDescriptor<Boolean> USE_MULTITHREADING
This GeneralParameterValue can be provided to the GridCoverageReaders through the GridCoverageReader.read(GeneralParameterValue[]) method in order to specify to use multithreading when leveraging on a JAI ImageRead operation. This will be achieved with the use of the ImageReadMT operation of the ImageIO-Ext.

Constructor Detail

JP2KFormat

public JP2KFormat()
Creates an instance and sets the metadata.

Method Detail

setInfo

protected void setInfo()
Sets the metadata information.


getReader

public AbstractGridCoverage2DReader getReader(Object source,
                                              Hints hints)
Description copied from class: AbstractGridFormat
Gets a GridCoverageReader for this format able to create coverages out of the source object using the provided hints.

In case this Format cannot reader the provided source object null is returned.

Specified by:
getReader in class AbstractGridFormat
Parameters:
source - The source object to parse. *
hints - The Hints to use when trying to instantiate this reader.
Returns:
A reader for this Format or null.

org.geotools.data.coverage.grid.AbstractGridFormat#getReader(Object, Hints)

getReader

public AbstractGridCoverage2DReader getReader(Object source)
Description copied from class: AbstractGridFormat
Gets a GridCoverageReader for this format able to create coverages out of the source object.

In case this Format cannot reader the provided source object null is returned.

Specified by:
getReader in class AbstractGridFormat
Parameters:
source - The source object to parse.
Returns:
A reader for this Format or null.
See Also:
org.geotools.data.coverage.grid.AbstractGridFormat#getReader(Object)

getWriter

public GridCoverageWriter getWriter(Object destination)
Description copied from class: AbstractGridFormat
Retrieves a GridCoverageWriter suitable for writing to the provided destination with this format.

In case no writers are availaible null is returned.

Specified by:
getWriter in class AbstractGridFormat
Parameters:
destination - The destinatin where to write.
Returns:
A GridCoverageWriter suitable for writing to the provided destination with this format.
See Also:
Actually, the plugin does not support write capabilities. The method throws an {@code UnsupportedOperationException}.

getDefaultImageIOWriteParameters

public GeoToolsWriteParams getDefaultImageIOWriteParameters()
Description copied from class: AbstractGridFormat
Returns an instance of ImageWriteParam that can be used to control a subsequent GridCoverageWriter.write(org.opengis.coverage.grid.GridCoverage, org.opengis.parameter.GeneralParameterValue[]);

Be careful with using the ImageWriteParam since their usage is still experimental.

Specified by:
getDefaultImageIOWriteParameters in class AbstractGridFormat
Returns:
an instance of ImageWriteParam.
See Also:
Actually, the plugin does not support write capabilities. The method throws an {@code UnsupportedOperationException}.

getWriter

public GridCoverageWriter getWriter(Object destination,
                                    Hints hints)
Description copied from class: AbstractGridFormat
Call the accepts() method before asking for a writer to determine if the current object is supported.

Specified by:
getWriter in class AbstractGridFormat
Parameters:
destination - the destination object to write a WorldImage to
hints - Hints to control the internal machinery.
Returns:
a new WorldImageWriter for the destination
See Also:
Actually, the plugin does not support write capabilities. The method throws an {@code UnsupportedOperationException}.

accepts

public boolean accepts(Object input,
                       Hints hints)
Description copied from class: AbstractGridFormat
Tells me if this Format can read the provided input.

Specified by:
accepts in class AbstractGridFormat
hints - Hints to control the accepts internal machinery.
Returns:
True if this format can read this object, False otherwise.
