Constructor Detail

VectorAccessor

public VectorAccessor(FunctionType funcType,
                      VectorAdapter vectorAdapter,
                      SampledSet domain,
                      dods.dap.PrimitiveVector vector)

Constructs from a function-type, a vector adapter, a domain and a DODS primitive vector.

Parameters:

funcType - The function-type for the FlatField.

vectorAdapter - The vector adapter corresponding to the DODS primitive vector.

domain - The domain for the FileFlatField.

vector - The DODS primitive vector.

Method Detail

getFunctionType
