Constructor Summary

RemoteDataReferenceImpl(DataReferenceImpl ref)
construct a RemoteDataReferenceImpl adapting the given DataReferenceImpl

Method Summary

Data	getData() return referenced Data object, but if Data is a FieldImpl return a RemoteFieldImpl referencing Data to avoid copying entire FieldImpl between JVMs
MathType	getType() this is more efficient than getData().getType() for RemoteDataReferences

Constructor Detail

RemoteDataReferenceImpl

public RemoteDataReferenceImpl(DataReferenceImpl ref)
                        throws RemoteException

construct a RemoteDataReferenceImpl adapting the given DataReferenceImpl

Parameters:

ref - adpted DataReferenceImpl

Throws:

RemoteException - an RMI error occurred

Method Detail

setData

public void setData(Data d)
             throws VisADException,
                    RemoteException

set this RemoteDataReferenceImpl to refer to given Data

Specified by:

setData in interface DataReference

Parameters:

d - Data to be set (must be RemoteDataImpl)

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

getData

public Data getData()
             throws VisADException,
                    RemoteException

return referenced Data object, but if Data is a FieldImpl return a RemoteFieldImpl referencing Data to avoid copying entire FieldImpl between JVMs

Specified by:

getData in interface DataReference

Returns:

referenced Data object, or null if none

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred

getType

public MathType getType()
                 throws VisADException,
                        RemoteException

this is more efficient than getData().getType() for RemoteDataReferences

Specified by:

getType in interface DataReference

Returns:

the MathType of referenced Data object, or null if none;

Throws:

VisADException - a VisAD error occurred

RemoteException - an RMI error occurred
