Method Summary

XDMIterator[]	getAllSubIters()
QName	getFunctionName()
PendingUpdateList	getPendingUpdateList() Returns the complete Pending Update List (PUL) of this iterator.
UserdefFuncCall	getResolvedFunc()
void	lookup()
Token	next() Produces the next XDM token This method typically implements the base functionality of an Iterator and computes the value of the next token.
void	setResettable(boolean r) Set this Iterator (and its subiterators) resetable.

Method Detail

lookup

public void lookup()
            throws MXQueryException

Throws:

MXQueryException

next

public Token next()
           throws MXQueryException

Description copied from interface: XDMIterator

Produces the next XDM token This method typically implements the base functionality of an Iterator and computes the value of the next token.

Returns:

The XDM token representing the next fragment of the XDM instance

Throws:

MXQueryException

setResettable

public void setResettable(boolean r)
                   throws MXQueryException

Description copied from interface: XDMIterator

Set this Iterator (and its subiterators) resetable. Resetable iterators may require more space (trading buffered data against recomputation)

Specified by:

setResettable in interface XDMIterator

Overrides:

setResettable in class Iterator

Parameters:

r - true make this iterator resetable, false make it not resetable

Throws:

MXQueryException

getFunctionName

public QName getFunctionName()

getAllSubIters

public XDMIterator[] getAllSubIters()

Specified by:

getAllSubIters in interface XDMIterator

Overrides:

getAllSubIters in class Iterator

getResolvedFunc

public UserdefFuncCall getResolvedFunc()

getPendingUpdateList

public PendingUpdateList getPendingUpdateList()
                                       throws MXQueryException

Description copied from interface: XDMIterator

Returns the complete Pending Update List (PUL) of this iterator. Is null for non-updating expressions. Since the PUL is computed gradually (especially in a scripting environment, this function should only be called when the evaluation is complete. For scripting, this function also merges the PULs of the child iterators, so

Specified by:

getPendingUpdateList in interface XDMIterator

Overrides:

getPendingUpdateList in class Iterator

Returns:

pending update list

Throws:

MXQueryException
