Example 1 with CommonASTWithHiddenTokens

use of antlr.CommonASTWithHiddenTokens in project processing by processing.

the class PdeEmitter method printIfThenElse.

    // optional "else" clause: an SLIST or an EXPR
    // what could be simpler?

Example 2 with CommonASTWithHiddenTokens

use of antlr.CommonASTWithHiddenTokens in project processing by processing.

the class PdeEmitter method dumpHiddenBefore.

/**
   * Dump the list of hidden tokens linked to before the AST node passed in.
   * The only time hidden tokens need to be dumped with this function is when
   * dealing parts of the tree where automatic tree construction was
   * turned off with the ! operator in the grammar file and the nodes were
   * manually constructed in such a way that the usual tokens don't have the
   * necessary hiddenAfter links.
