Examples of org.antlr.runtime.tree.TreeWizard.create()

org.antlr.runtime.tree.TreeWizard.create()
Create a tree or node from the indicated tree pattern that closely follows ANTLR tree grammar tree element syntax: (root child1 ... child2). You can also just pass in a node: ID Any node can have a text argument: ID[foo] (notice there are no quotes around foo--it's clear it's a string). nil is a special name meaning "give me a nil node". Useful for making lists: (nil A B C) is a list of A B C.

    assertEquals("C", labels.get("c").toString());
