Example 1 with ElseTokenNode

use of com.google.auto.value.processor.escapevelocity.TokenNode.ElseTokenNode in project auto by google.

the class Reparser method parseIfOrElseIf.

        // after (condition2). We pretend that we've just seen #if (condition2) and parse out
        // the remainder (which might have further #elseif and final #else). Then we pretend that

Example 2 with ElseTokenNode

the class Parser method parseDirective.

   * braces, for example {@code #if} or {@code #{if}}. We omit the brace spelling in the productions
   * here: <pre>{@code
