Method Detail

isValidFile

public boolean isValidFile(RandomAccessFile raf)

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.

getFileTypeId

public java.lang.String getFileTypeId()

Description copied from interface: IOServiceProvider

Get a unique id for this file type.

Returns:

registered id of the file type

getFileTypeDescription

public java.lang.String getFileTypeDescription()

Description copied from interface: IOServiceProvider

Get a human-readable description for this file type.

Returns:

description of the file type

See Also:

"http://www.unidata.ucar.edu/software/netcdf-java/formats/FileTypes.html"

open

public void open(RandomAccessFile raf,
                 NetcdfFile file,
                 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.

file - add objects to this empty NetcdfFile

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

Throws:

java.io.IOException - if read error

readData

public Array readData(Variable v2,
                      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:

v2 - 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

See Also:

Range
