Method Detail

isValidFile

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

Check if this is a valid file for this IOServiceProvider.

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

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:

java.io.IOException - if read error

makeSequence

protected Sequence makeSequence(NetcdfFile ncfile)

addLightningGlobalAttributes

protected void addLightningGlobalAttributes(NetcdfFile ncfile)

Add the global attributes.

Overrides:

addLightningGlobalAttributes in class AbstractLightningIOSP

Parameters:

ncfile - the file to add to

readData

public Array readData(Variable v2,
                      Section section)
               throws java.io.IOException,
                      InvalidRangeException

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

getStructureIterator

public StructureDataIterator getStructureIterator(Structure s,
                                                  int bufferSize)
                                           throws java.io.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:

java.io.IOException - if problem reading data

getFileTypeId

public java.lang.String getFileTypeId()

Get a unique id for this file type.

Returns:

registered id of the file type

getFileTypeDescription

public java.lang.String getFileTypeDescription()

Get a human-readable description for this file type.

Returns:

description of the file type

getFileTypeVersion

public java.lang.String getFileTypeVersion()

Get the version of this file type.

Specified by:

getFileTypeVersion in interface IOServiceProvider

Overrides:

getFileTypeVersion in class AbstractIOServiceProvider

Returns:

version of the file type
