ObjectAbstractGridFormat
BaseGDALGridFormat
public abstract class BaseGDALGridFormat
A Base abstract class implementing Format
, to be extended by Formats
leveraging on GDAL.
Field Summary | |
---|---|
static DefaultParameterDescriptor<Boolean> |
USE_MULTITHREADING
This GeneralParameterValue can be provided to the
GridCoverageReader s through the
GridCoverageReader.read(GeneralParameterValue[]) method in order
to specify to use multithreading when leveraging on a JAI ImageRead
operation. |
Constructor Summary | |
---|---|
protected |
BaseGDALGridFormat(ImageReaderSpi spi)
Constructor for the BaseGDALGridFormat . |
Method Summary | |
---|---|
boolean |
accepts(Object input,
Hints hints)
Tells me if this Format can read the provided input . |
GeoToolsWriteParams |
getDefaultImageIOWriteParameters()
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. |
protected static ParameterGroup |
getDefaultParameterGroup(Map<String,String> mInfo)
Return a ParameterGroup with default General Parameter Descriptors. |
AbstractGridCoverage2DReader |
getReader(Object source)
Gets a GridCoverageReader for this format able to create
coverages out of the source object. |
GridCoverageWriter |
getWriter(Object destination)
Retrieves a GridCoverageWriter suitable for writing to the
provided destination with this format. |
GridCoverageWriter |
getWriter(Object destination,
Hints hints)
Call the accepts() method before asking for a writer to determine if the current object is supported. |
protected abstract void |
setInfo()
Each plugin needs to implement this method defining format specific properties |

public static final DefaultParameterDescriptor<Boolean> USE_MULTITHREADING
GeneralParameterValue
can be provided to the
GridCoverageReader
s 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.
