extractObject

protected java.lang.Object extractObject(dap4.core.dmr.DapType basetype,
                                         java.nio.ByteBuffer dataset,
                                         long index)

Extract, as an object, value from a (presumably) atomic typed array of values; dataset position is presumed correct.

Parameters:

basetype - type of object to extract

dataset - ByteBuffer containing databuffer; position assumed correct

Returns:

resulting value as an Object; value does not necessarily conform to Convert.ValueClass.

extractObjectVector

protected void extractObjectVector(dap4.core.dmr.DapType basetype,
                                   java.nio.ByteBuffer dataset,

                                   long offset)

Vector version of extractObject(). Extract a vector of objects from a (presumably) atomic typed array of values; dataset position is presumed correct.

Parameters:

basetype - type of object to extract ; must not be Enum

dataset - ByteBuffer containing databuffer; position assumed correct

vector -

count -
