flush

public DSPPrinter flush()

close

public DSPPrinter close()

print

public DSPPrinter print()
                 throws DapException

Print data from a DSP - optionally constrained

Throws:

DapException

printVariable

protected void printVariable(DataCursor data,
                             java.util.List<Slice> slices)
                      throws DapException

Print an arbitrary DataVariable using a constraint.

Handling newlines is a bit tricky so the rule is that the last newline is elided and left for the caller to print. Exceptions: ?

Parameters:

data - - the cursor to print

Throws:

DapException - Note that the PrintWriter and CEConstraint are global.

printScalar

protected void printScalar(DataCursor data)
                    throws DapException

Throws:

DapException

printArray

protected void printArray(DataCursor data,
                          java.util.List<Slice> slices)
                   throws DapException

Throws:

DapException

printAtomicVector

protected void printAtomicVector(DataCursor data,
                                 java.util.List<Slice> slices,
                                 Odometer odom)
                          throws DapException

Throws:

DapException

printAtomicInstance

protected void printAtomicInstance(DataCursor datav,
                                   Index pos)
                            throws DapException

Throws:

DapException

printCompoundInstance

protected void printCompoundInstance(DataCursor datav)
                              throws DapException

Print a single structure or sequence or record instance

Parameters:

datav -

Throws:

DapException

indicesToString

protected java.lang.String indicesToString(Index indices)
                                    throws DapException

Throws:

valueString

protected java.lang.String valueString(java.lang.Object vector,
                                       long pos,
                                       DapType basetype)
                                throws DapException

Throws:
