Constructor Detail

NcSDStructure

public NcSDStructure(ucar.nc2.Structure s,
                     List<opendap.dap.BaseType> list)

Constructor.

Parameters:

s - the netcdf Structure

list - of the member variables

NcSDStructure

public NcSDStructure(NcSDStructure org,
                     ucar.ma2.StructureData sdata)

Method Detail

getVariable

public ucar.nc2.Variable getVariable()

read

public boolean read(String datasetName,
                    Object specialO)
             throws opendap.dap.NoSuchVariableException,
                    IOException

Description copied from class: SDStructure

Read a value from the named dataset for this variable.

Specified by:

read in interface ServerMethods

Specified by:

read in class SDStructure

Parameters:

datasetName - String identifying the file or other data store from which to read a vaue for this variable.

specialO - This Object is a goody that is used by Server implementations to deliver important, and as yet unknown, stuff to the read method. If you don't need it, make it a null.

Returns:

true if more data remains to be read, otherwise false. This is an abtsract method that must be implemented as part of the installation/localization of a OPeNDAP server.

Throws:

opendap.dap.NoSuchVariableException - When a variable can't be found.

IOException - When there is a problem reading data.

setData

public void setData(ucar.ma2.StructureData sdata)

serialize

public void serialize(String dataset,
                      DataOutputStream sink,
                      CEEvaluator ce,
                      Object specialO)
               throws opendap.dap.NoSuchVariableException,
                      DAP2ServerSideException,
                      IOException

Description copied from class: SDStructure

Server-side serialization for OPeNDAP variables (sub-classes of BaseType). This does not send the entire class as the Java Serializable interface does, rather it sends only the binary data values. Other software is responsible for sending variable type information (see DDS).

Writes data to a DataOutputStream. This method is used on the server side of the OPeNDAP client/server connection, and possibly by GUI clients which need to download OPeNDAP data, manipulate it, and then re-save it as a binary file.

Specified by:

serialize in interface ServerMethods

Overrides:

serialize in class SDStructure

Parameters:

dataset - a String indicated which dataset to read from (Or something else if you so desire).

sink - a DataOutputStream to write to.

ce - the CEEvaluator to use in the parse process.

specialO - This Object is a goody that is used by a Server implementations to deliver important, and as yet unknown, stuff to the read method. If you don't need it, make it a null.

Throws:

opendap.dap.NoSuchVariableException - When a variable cannot be found.

DAP2ServerSideException - When there is a server error.

IOException - thrown on any OutputStream exception.
