-/**
- * Implements the filter specified by the {@link GraalOptions#Dump},
- * {@link GraalOptions#Log}, {@link GraalOptions#Meter} and {@link GraalOptions#Time}
- * options.
- * <p>
- * These options enable the associated debug facility if their filter
- * matches the {@linkplain DebugScope#getQualifiedName() name} of the
- * {@linkplain Debug#currentScope() current scope}.
- * <p>
- * A filter is a list of comma-separated terms. Each term is interpreted
- * as a glob pattern if it contains a "*" or "?" character. Otherwise, it is
- * interpreted as a substring. If a term starts with "~", then it is an
- * positive term. An input is matched by a filter if any of its positive
- * terms match the input (or it has no positive terms) AND none of its
- * negative terms match the input (or it has no negative terms).
- * <p>
- * Examples of filters include:
- * <p>
- * <ul>
- * <li><pre>""</pre>
- * Matches any scope.</li>
- * <li><pre>"*"</pre>
- * Matches any scope.</li>
- * <li><pre>"CodeGen,CodeInstall"</pre>
- * Matches a scope whose name contains "CodeGen" or "CodeInstall".</li>
- * <li><pre>"Code*"</pre>
- * Matches a scope whose name starts with "Code".</li>
- * <li><pre>"Code,~Dead"</pre>
- * Matches a scope whose name contains "Code" but does not contain "Dead".</li>
- * </ul>

-/**
- * This class implements a method filter that can filter based on class name, method name and parameters.
- * The syntax for the source pattern that is passed to the constructor is as follows:
- *
- * <pre>
- * SourcePattern = [ Class "." ] method [ "(" [ Parameter { ";" Parameter } ] ")" ] .
- * Parameter = Class | "int" | "long" | "float" | "double" | "short" | "char" | "boolean" .
- * Class = { package "." } class .
- * </pre>
- *
- *
- * Glob pattern matching (*, ?) is allowed in all parts of the source pattern. Examples for valid filters are:
- *
- * <ul>
- * <li><pre>visit(Argument;BlockScope)</pre>
- * Matches all methods named "visit", with the first parameter of type "Argument", and the second parameter of type "BlockScope".
- * The packages of the parameter types are irrelevant.</li>
