Since evaluation of an XPath expression can result in various 286N/A * result types, this object makes it possible to discover and manipulate 286N/A * the type and value of the result. 286N/A * This code does not represent a specific type. An evaluation of an XPath 286N/A * expression will never produce this type. If this type is requested, 286N/A * then the evaluation returns whatever type naturally results from 286N/A * evaluation of the expression. 286N/A * <br>If the natural result is a node set when <code>ANY_TYPE</code> was 286N/A * requested, then <code>UNORDERED_NODE_ITERATOR_TYPE</code> is always 286N/A * the resulting type. Any other representation of a node set must be 286N/A * explicitly requested. 286N/A * The result is a number as defined by . Document modification does not 286N/A * invalidate the number, but may mean that reevaluation would not yield 286N/A * The result is a string as defined by . Document modification does not 286N/A * invalidate the string, but may mean that the string no longer 286N/A * corresponds to the current document. 286N/A * The result is a boolean as defined by . Document modification does not 286N/A * invalidate the boolean, but may mean that reevaluation would not 286N/A * yield the same boolean. 286N/A * The result is a node set as defined by that will be accessed 286N/A * iteratively, which may not produce nodes in a particular order. 286N/A * Document modification invalidates the iteration. 286N/A * <br>This is the default type returned if the result is a node set and 286N/A * <code>ANY_TYPE</code> is requested. 286N/A * The result is a node set as defined by that will be accessed 286N/A * iteratively, which will produce document-ordered nodes. Document 286N/A * modification invalidates the iteration. 286N/A * The result is a node set as defined by that will be accessed as a 286N/A * snapshot list of nodes that may not be in a particular order. 286N/A * Document modification does not invalidate the snapshot but may mean 286N/A * that reevaluation would not yield the same snapshot and nodes in the 286N/A * snapshot may have been altered, moved, or removed from the document. 286N/A * The result is a node set as defined by that will be accessed as a 286N/A * snapshot list of nodes that will be in original document order. 286N/A * Document modification does not invalidate the snapshot but may mean 286N/A * that reevaluation would not yield the same snapshot and nodes in the 286N/A * snapshot may have been altered, moved, or removed from the document. 286N/A * The result is a node set as defined by and will be accessed as a 286N/A * single node, which may be <code>null</code>if the node set is empty. 286N/A * Document modification does not invalidate the node, but may mean that 286N/A * the result node no longer corresponds to the current document. This 286N/A * is a convenience that permits optimization since the implementation 286N/A * can stop once any node in the in the resulting set has been found. 286N/A * <br>If there are more than one node in the actual result, the single 286N/A * node returned might not be the first in document order. 286N/A * The result is a node set as defined by and will be accessed as a 286N/A * single node, which may be <code>null</code> if the node set is empty. 286N/A * Document modification does not invalidate the node, but may mean that 286N/A * the result node no longer corresponds to the current document.
