public interface IOServiceProviderWriter
This is really just an interface to Netcdf-3 file writing. However, we will probably add Netcdf-4 writing, even if its only through a JNI interface. For now, other parties are discouraged from using this, as it will likely be refactored in 4.x.

void create(String filename, NetcdfFile ncfile, int extra, long preallocateSize, boolean largeFile) throws IOException
filename
- name of file to create.ncfile
- get dimensions, attributes, and variables from here.extra
- if > 0, pad header with extra bytespreallocateSize
- if > 0, set length of file to this upon creation - this (usually) pre-allocates contiguous storage.largeFile
- if want large file format
IOException
- if I/O errorvoid setFill(boolean fill)
fill
- set fill mode true or falsevoid writeData(Variable v2, Section section, Array values) throws IOException, InvalidRangeException
v2
- variable to write; must already exist.section
- the section of data to write.
There must be a Range for each Dimension in the variable, in order.
The shape must match the shape of values.
The origin and stride indicate where the data is placed into the stored Variable array.values
- data to write. The shape must match section.getShape().
IOException
- if I/O error
InvalidRangeException
- if invalid sectionboolean rewriteHeader(boolean largeFile) throws IOException
IOException
void updateAttribute(Variable v2, Attribute att) throws IOException
v2
- variable, or null for global attributeatt
- replace with this value
IOException
- if I/O errorvoid flush() throws IOException
IOException
- if I/O error
