Method Detail

read

public GridCoverage read(GeneralParameterValueIm[] parameters)
                  throws InvalidParameterNameException,
                         InvalidParameterValueException,
                         ParameterNotFoundException,
                         java.io.IOException
Read the grid coverage from the current stream position, and move to the next grid coverage.

Parameters:
parameters - An optional set of parameters. Should be any or all of the parameters returned by "org.opengis.coverage.grid.Format#getReadParameters".
Returns:
A new 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.
java.io.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.

dispose

public void dispose()
             throws java.io.IOException
Allows any resources held by this object to be released. The result of calling any other method subsequent to a call to this method is undefined. It is important for applications to call this method when they know they will no longer be using this GridCoverageReader. Otherwise, the reader may continue to hold on to resources indefinitely.

Throws:
java.io.IOException - if an error occured while disposing resources (for example while closing a file).
