Package org.geotools.api.coverage.grid

Interface GridCoverageWriter

All Known Implementing Classes:
AbstractGridCoverageWriter, ArcGridWriter, GeoTiffWriter, GrassCoverageWriter, WorldImageWriter
public interface GridCoverageWriter
Support for writing grid coverages into a persistent store. Instance of GridCoverageWriter are obtained through a call to AbstractGridFormat.getWriter. Grid coverages are usually added to the output stream in a sequential order.
Since:
GeoAPI 2.0

  • Method Details

    • getFormat

      Format getFormat()
      Returns the format handled by this GridCoverageWriter.

    • getDestination

      Object getDestination()
      Returns the output destination. This is the object passed to the AbstractGridFormat.getWriter method. It can be a String, an OutputStream, a FileChannel, etc.

    • getMetadataNames

      String[] getMetadataNames()
      Returns the list of metadata keywords associated with the output destination as a whole (not associated with any particular grid coverage). If no metadata is allowed, the array will be empty.
      Returns:
      The list of metadata keywords for the output destination.

    • setMetadataValue

      void setMetadataValue(String name, String value) throws IOException
      Sets the metadata value for a given metadata name.
      Parameters:
      name - Metadata keyword for which to set the metadata.
      value - The metadata value for the given metadata name.
      Throws:
      IOException - if an error occurs during writing.

    • setCurrentSubname

      void setCurrentSubname(String name) throws IOException
      Set the name for the next grid coverage to write within the output destination. The subname can been fetch later at reading time.
      Throws:
      IOException - if an error occurs during writing.

    • write

      void write(GridCoverage coverage, GeneralParameterValue... parameters) throws IllegalArgumentException, IOException
      Writes the specified grid coverage.
      Parameters:
      coverage - The grid coverage to write.
      parameters - An optional set of parameters. Should be any or all of the parameters returned by Format.getWriteParameters().
      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.
      FileFormatNotCompatibleWithGridCoverageException - if the grid coverage can't be exported in the writer format.
      IOException - if the export failed for some other input/output reason, including IIOException if an error was thrown by the underlying image library.
      IllegalArgumentException

    • dispose

      void dispose() throws 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 GridCoverageWriter. Otherwise, the writer may continue to hold on to resources indefinitely.
      Throws:
      IOException - if an error occured while disposing resources (for example while flushing data and closing a file).
