JavaConverter

public JavaConverter(Cluster cluster,

Method Detail

clone

public Object clone()

Specified by:

clone in class Rel

getConvention

public CallingConvention getConvention()

Description copied from class: Rel

Returns a value from CallingConvention.

Overrides:

getConvention in class Rel

init

public static void init(Planner planner)

implement

public Object implement(Implementor implementor,
                        int ordinal)

Description copied from class: Rel

Create a plan for this expression according to a calling convention.

Overrides:

implement in class Converter

Parameters:

implementor - implementor

ordinal - indicates our position in the pre-, in- and postfix walk over the tree; ordinal is -1 when called from the parent, and i when called from the i^th child.

implementArray

private Object implementArray(Implementor implementor,
                              int ordinal)

implementIterator

private Object implementIterator(Implementor implementor,
                                 int ordinal)

implementIterable

                               int ordinal)

implementEnumeration

private Object implementEnumeration(Implementor implementor,
                                    int ordinal)

implementMap

private Object implementMap(Implementor implementor,
                            int ordinal)

implementHashtable
