Examples with TerminalNodeImpl org.antlr.v4.runtime.tree.TerminalNodeImpl used on opensource projects

Example 1 with TerminalNodeImpl

use of org.antlr.v4.runtime.tree.TerminalNodeImpl in project antlr4 by antlr.

the class ParserRuleContext method addChild.

/** Add a child to this node based upon matchedToken. It
	 *  creates a TerminalNodeImpl rather than using
	 *  {@link Parser#createTerminalNode(ParserRuleContext, Token)}. I'm leaving this
     *  in for compatibility but the parser doesn't use this anymore.

    TerminalNodeImpl t = new TerminalNodeImpl(matchedToken);
    addAnyChild(t);

Example 2 with TerminalNodeImpl

use of org.antlr.v4.runtime.tree.TerminalNodeImpl in project antlr4 by antlr.

the class Trees method stripChildrenOutOfRange.

/** Replace any subtree siblings of root that are completely to left
	 *  or right of lookahead range with a CommonToken(Token.INVALID_TYPE,"...")
	 *  node. The source interval for t is not altered to suit smaller range!
	 *
	 *  WARNING: destructive to t.
