Method Detail

getFormat

public Format getFormat()

Description copied from interface: GridCoverageReader

Returns the format handled by this GridCoverageReader.

Specified by:

getFormat in interface GridCoverageReader

read

public GridCoverage2D read(GeneralParameterValue[] params)
                    throws IllegalArgumentException,
                           IOException

Description copied from class: AbstractGridCoverage2DReader

Read the current grid coverage from the stream.

Example:

The method AbstractGridCoverage2DReader.hasMoreGridCoverages() should be invoked first in order to verify that a coverage is available.

Specified by:

read in interface GridCoverageReader

Specified by:

read in class AbstractGridCoverage2DReader

Parameters:

params - Optional parameters matching Format.getReadParameters().

Returns:

a grid coverage from the input source.

Throws:

InvalidParameterNameException - if a parameter in parameters doesn't have a recognized name.

InvalidParameterValueException - if a parameter in parameters doesn't have a valid value.

ParameterNotFoundException - if a parameter was required for the operation but was not provided in the parameters list.

IOException - if a read operation failed for some other input/output reason, including FileNotFoundException if no file with the given name can be found, or IIOException if an error was thrown by the underlying image library.
