Constructor Summary

protected

FloatVectorAdapter(dods.dap.PrimitiveVector vector, dods.dap.DAS das, VariableAdapterFactory factory) Constructs from a DODS vector and a factory for creating DODS variable adapters.

Method Summary

protected abstract float[]	getFloats(dods.dap.PrimitiveVector vector, boolean copy) Returns the numeric values of a compatible DODS primitive vector.
GriddedSet	griddedSet(dods.dap.PrimitiveVector vector) Returns the VisAD GriddedSet corresponding to the metadata of the DODS primitive vector used during construction of this instance and the data values of a compatible DODS primitive vector.
void	setField(dods.dap.PrimitiveVector vector, FieldImpl field, boolean copy) Sets the range of a compatible VisAD Field.

FloatVectorAdapter

protected FloatVectorAdapter(dods.dap.PrimitiveVector vector,
                             dods.dap.DAS das,
                             VariableAdapterFactory factory)
                      throws BadFormException,
                             VisADException,
                             RemoteException

Constructs from a DODS vector and a factory for creating DODS variable adapters.

Parameters:

vector - A DODS vector to be adapted.

das - The DODS DAS in which the attribute table for the DODS vector is embedded.

factory - A factory for creating adapters of DODS variables.

Throws:

BadFormException - The DODS information is corrupt.

VisADException - VisAD failure.

RemoteException - Java RMI failure.

Method Detail

setField

public final void setField(dods.dap.PrimitiveVector vector,
                           FieldImpl field,
                           boolean copy)
                    throws VisADException,
                           RemoteException

Sets the range of a compatible VisAD Field. The range values are taken from a DODS primitive vector whose metadata must be compatible with the metadata of the primitive vector used during construction of this instance.

Specified by:

setField in class NumericVectorAdapter

Parameters:

vector - A DODS primitive vector whose data values are to be used to set the range of the VisAD field.

field - A VisAD field to have its range values set.

copy - If true, then the range values are copied from the primitive vector.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

griddedSet

public GriddedSet griddedSet(dods.dap.PrimitiveVector vector)
                      throws VisADException,
                             RemoteException

Returns the VisAD GriddedSet corresponding to the metadata of the DODS primitive vector used during construction of this instance and the data values of a compatible DODS primitive vector.

Specified by:

griddedSet in class NumericVectorAdapter

Parameters:

vector - A DODS primitive vector whose metadata is compatible with the metadata of the primitive vector used in construting this instance.

Returns:

A VisAD GriddedSet corresponding to the input. The (super)class of the object is Gridded1DSet.

Throws:

VisADException - VisAD failure.

RemoteException - Java RMI failure.

getFloats

protected abstract float[] getFloats(dods.dap.PrimitiveVector vector,
                                     boolean copy)

Returns the numeric values of a compatible DODS primitive vector.

Parameters:

vector - A DODS primitive vector that is compatible with the primitive vector used to construct this instance.

copy - If true, then a copy is returned.

Returns:

The numeric values of the primitive vector.
