Method Detail

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

open

public void open(RandomAccessFile raf,
                 NetcdfFile ncfile,
                 Message single)
          throws IOException

Throws:

IOException

sendIospMessage

public Object sendIospMessage(Object message)

Description copied from interface: IOServiceProvider

A way to communicate arbitrary information to an iosp.

Specified by:

sendIospMessage in interface IOServiceProvider

Overrides:

sendIospMessage in class AbstractIOServiceProvider

Parameters:

message - opaque message sent to the IOSP object when its opened (not when isValidFile() is called)

Returns:

opaque return, may be null.

getConfig

public BufrConfig getConfig()

getElem

public org.jdom2.Element getElem()

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

Range

getStructureIterator

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

Description copied from interface: IOServiceProvider

Get the structure iterator. iosps with top level sequences must override. Not threadsafe; do not use multiple StructureDataIterator for the same iosp.

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

getFileTypeDescription

public String getFileTypeDescription()

Description copied from interface: IOServiceProvider

Get a human-readable description for this file type.

Returns:

description of the file type
