static Window	getNewWindow(Context context, XDMIterator sourceIter, int startPosition, int endPosition) Returns a new window iterator on the source with specific start and end positions
static Window	getNewWindow(Context runtime, XDMIterator sourceIter, int startPosition, int endPosition, boolean sync) Returns a new window iterator for a source sequence.

Method Detail

getNewWindow

public static Window getNewWindow(Context runtime,
                                  XDMIterator sourceIter,
                                  int startPosition,
                                  int endPosition,
                                  boolean sync)
                           throws MXQueryException

Returns a new window iterator for a source sequence. When the source sequence is already by an WindowBuffer the returned window works than on the same buffer

Parameters:

sourceIter -

startPosition -

endPosition -

sync -

Returns:

a new Window for the iterator, spanning the given start and end positions

Throws:

MXQueryException

getNewWindow_Eager

public static Window getNewWindow_Eager(Context runtime,
                                        XDMIterator sourceIter)
                                 throws MXQueryException

TODO Can be deleted as soon as the eager materialization of irinas store works.

Parameters:

sourceIter -

Returns:

an eagerly (i.e. completely on first call) materializing window

Throws:

MXQueryException

getNewWindow

public static Window getNewWindow(Context context,
                                  XDMIterator sourceIter)
                           throws MXQueryException

Returns a new window iterator on the source and creates a store (if there is not already one)

Parameters:

context -

sourceIter -

Returns:

A window for the given input iterator

Throws:

MXQueryException

getNewWindow

public static Window getNewWindow(Context context,
                                  XDMIterator sourceIter,
                                  boolean sync)
                           throws MXQueryException

The same as getNewWindowInterface(Iterator sourceIter) but with synhronization for LR

Parameters:

context -

sourceIter -

sync -

Returns:

a window for the given input iterator

Throws:

MXQueryException

getNewWindow

public static Window getNewWindow(Context context,
                                  XDMIterator sourceIter,
                                  int startPosition,
                                  int endPosition)
                           throws MXQueryException

Returns a new window iterator on the source with specific start and end positions

Parameters:

context -

sourceIter -

startPosition - start of the window

endPosition - end of the window

Returns:

a window for this input, spanning the given positions

Throws:

MXQueryException
