org.apache.jackrabbit.name.Path

The Path utility class provides misc. methods to resolve and nornalize JCR-style item paths.

Each path consistnes of path elements and is immutable. It has the following properties:

isAbsolute():
A path is absolute if the first path element denotes the root element '/'.

isNormalized():
A path is normalized if all '.' and '..' path elements are resolved as much as possible. If the path is absolute it is normalized if it contains no such elements. For example the path '../../a' is normalized where as '../../b/../a/.' is not. Normalized paths never have '.' elements. Absolute normalized paths have no and relative normalized paths have no or only leading '..' elements.

isCanonical():
A path is canonical if its absolute and normalized.

String representations

The JCR path format is specified by JSR 170 as follows:

 path ::= properpath ['/'] properpath ::= abspath | relpath abspath ::= '/' relpath relpath ::= pathelement | relpath '/' pathelement pathelement ::= name | name '[' number ']' | '..' | '.' number ::= (* An integer > 0 *) name ::= simplename | prefixedname simplename ::= onecharsimplename | twocharsimplename | threeormorecharname prefixedname ::= prefix ':' localname localname ::= onecharlocalname | twocharlocalname | threeormorecharname onecharsimplename ::= (* Any Unicode character except: '.', '/', ':', '[', ']', '*', ''', '"', '|' or any whitespace character *) twocharsimplename ::= '.' onecharsimplename | onecharsimplename '.' | onecharsimplename onecharsimplename onecharlocalname ::= nonspace twocharlocalname ::= nonspace nonspace threeormorecharname ::= nonspace string nonspace prefix ::= (* Any valid XML Name *) string ::= char | string char char ::= nonspace | ' ' nonspace ::= (* Any Unicode character except: '/', ':', '[', ']', '*', ''', '"', '|' or any whitespace character *)
