Constructor Detail

BCP

public BCP(PyConnection source,
           PyConnection destination)

The source connection will produce the rows while the destination connection will consume the rows and coerce as necessary for the destination database.

BCP

public BCP(PyConnection source,
           PyConnection destination,
           int batchsize)

The source connection will produce the rows while the destination connection will consume the rows and coerce as necessary for the destination database.

Parameters:

batchsize - used to batch the inserts on the destination

Method Detail

toString

public java.lang.String toString()

String representation of the object.

Overrides:

toString in class PyObject

Returns:

a string representation of the object.

__setattr__

public void __setattr__(java.lang.String name,
                        PyObject value)

Sets the attribute name to value.

Overrides:

__setattr__ in class PyObject

Parameters:

name -

value -

See Also:

PyObject.__setattr__(PyString, PyObject)

__findattr_ex__

public PyObject __findattr_ex__(java.lang.String name)

Gets the value of the attribute name.

Overrides:

__findattr_ex__ in class PyObject

Parameters:

name -

Returns:

the attribute for the given name

classDictInit

public static void classDictInit(PyObject dict)

Initializes the object's namespace.

Parameters:

dict -

traverse

public int traverse(Visitproc visit,
                    java.lang.Object arg)

Description copied from interface: Traverseproc

Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.

Specified by:

traverse in interface Traverseproc

refersDirectlyTo

public boolean refersDirectlyTo(PyObject ob)

Description copied from interface: Traverseproc

Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

Specified by:

refersDirectlyTo in interface Traverseproc
