Method Detail

isValidFile

public boolean isValidFile(RandomAccessFile raf)
                    throws java.io.IOException

Description copied from interface: IOServiceProvider

Check if this is a valid file for this IOServiceProvider. You must make this method thread safe, ie dont keep any state.

Parameters:

raf - RandomAccessFile

Returns:

true if valid.

Throws:

java.io.IOException - if read error

open

public void open(RandomAccessFile raf,
                 NetcdfFile ncfile,
                 CancelTask cancelTask)
          throws java.io.IOException

Description copied from interface: IOServiceProvider

Open existing file, and populate ncfile with it. This method is only called by the NetcdfFile constructor on itself. The provided NetcdfFile object will be empty except for the location String and the IOServiceProvider associated with this NetcdfFile object.

Parameters:

raf - the file to work on, it has already passed the isValidFile() test.

ncfile - add objects to this empty NetcdfFile

cancelTask - used to monitor user cancellation; may be null.

Throws:

java.io.IOException - if read error

close

public void close()
           throws java.io.IOException

Description copied from interface: IOServiceProvider

Close the file. It is the IOServiceProvider's job to close the file (even though it didnt open it), and to free any other resources it has used.

Throws:

java.io.IOException - if read error

readData

public Array readData(Variable v,
                      Section section)
               throws java.io.IOException,
                      InvalidRangeException

Description copied from interface: IOServiceProvider

Read data from a top level Variable and return a memory resident Array. This Array has the same element type as the Variable, and the requested shape.

Parameters:

v - a top-level Variable

section - the section of data to read. There must be a Range for each Dimension in the variable, in order. Note: no nulls allowed. IOSP may not modify.

Returns:

the requested data in a memory-resident Array

Throws:

java.io.IOException - if read error

InvalidRangeException - if invalid section
