Example 1 with LabelRef

use of org.eclipse.n4js.n4JS.LabelRef in project n4js by eclipse.

the class N4JSLinker method createProxy.

/**
 * Creates the proxy with a custom encoded URI format (starting with "|"). The object used to produce the encoded
 * URI are collected as tuple inside {@link N4JSResource}. Then the node text is checked if it is convertible to a
 * valid value. If there is a {@link BadEscapementException} is thrown then there is either a warning or an error
 * produced via the diagnosticProducer.
