Constructor Detail

DataCompiler

public DataCompiler(D4DSP dsp,
            ChecksumMode checksummode,
            ByteBuffer databuffer)
             throws DapException

Constructor

Parameters:

dsp - the D4DSP

checksummode -

databuffer - the source of serialized databuffer

Throws:

DapException

Method Detail

compile

public void compile()
             throws DapException

The goal here is to process the serialized databuffer and locate variable-specific positions in the serialized databuffer. For each DAP4 variable, D4Array objects are created and linked together.

Throws:

DapException

compileVar

protected D4DataVariable compileVar(DapVariable dapvar)
                             throws DapException

Throws:

DapException

compileAtomicVar

protected D4DataAtomic compileAtomicVar(DapVariable dapvar)
                                 throws DapException

Throws:

DapException

getChecksum

protected byte[] getChecksum(ByteBuffer data)
                      throws DapException

Throws:

DapException

skip

protected static void skip(ByteBuffer data,
        int count)

getCount

protected static int getCount(ByteBuffer data)

computeTypeSize

protected static int computeTypeSize(DapType daptype)

Compute the size in databuffer of the serialized form

Parameters:

daptype -

Returns:

type's serialized form size

walkByteStrings

protected static long walkByteStrings(int[] positions,
                   ByteBuffer databuffer)
