Class NetcdfFileWriteable

  • All Implemented Interfaces:
    Closeable, AutoCloseable, FileCacheable

    public class NetcdfFileWriteable
    extends NetcdfFile
    Deprecated.
    use NetcdfFileWriter
    Create/Write netCDF-3 formatted files.

    When a file is first created, it is in is "define mode", where the header objects (Dimensions, Attributes and Variables) may be added, deleted and modified, but no data may be written. Once create() is called, you can no longer modify the header, but you can now write data. An existing file is opened in write mode.

    If setRedefine(true) is called, the file goes into define mode, and header objects can be changed. When setRedefine(false) is called, the new header is written, and the old file data is copied to the new file. This can be quite costly.
