setDebugFlags

public static void setDebugFlags(DebugFlags debugFlag)

isValidFile

public boolean isValidFile(RandomAccessFile raf)
                    throws 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:

IOException - if read error

open

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

Specified by:

open in interface IOServiceProvider

Overrides:

open in class AbstractIOServiceProvider

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:

IOException - if read error

readData

public Array readData(Variable v2,
                      Section section)
               throws 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:

IOException - if read error

InvalidRangeException - if invalid section

getStructureIterator

public StructureDataIterator getStructureIterator(Structure s,
                                                  int bufferSize)
                                           throws IOException

Get the structure iterator

Specified by:

getStructureIterator in interface IOServiceProvider

Overrides:

getStructureIterator in class AbstractIOServiceProvider

Parameters:

s - the Structure

bufferSize - the buffersize

Returns:

the data iterator

Throws:

IOException - if problem reading data

getDetailInfo

public String getDetailInfo()

Description copied from interface: IOServiceProvider

Show debug / underlying implementation details

Specified by:

getDetailInfo in interface IOServiceProvider

Overrides:

getDetailInfo in class AbstractIOServiceProvider

Returns:

debug info

getFileTypeId

public String getFileTypeId()

Description copied from interface: IOServiceProvider

Get a unique id for this file type.

Returns:

registered id of the file type
