List of resolveBackReferences() Examples

Examples of resolveBackReferences()

org.jnode.shell.syntax.MuAlternation.resolveBackReferences()
org.jnode.shell.syntax.MuSyntax.resolveBackReferences()
Resolve any MuBackReference instances in this syntax tree.
The algorithm has the following limitations:
- References to ancestor syntax nodes (true back references) are guaranteed to be resolvable. References to sibling or cousin syntax nodes may not be resolvable, depending on whether or not the target is encountered before the reference in the tree traversal order.
- If SyntaxFailureException is thrown, the syntax tree may be left in a partially resolved state.
@throws SyntaxFailureException if any MuBackReference cannot be resolved.
