Examples of org.antlr.stringtemplate.StringTemplate

org.antlr.stringtemplate.StringTemplate
A StringTemplate is a "document" with holes in it where you can stick values. StringTemplate breaks up your template into chunks of text and attribute expressions. StringTemplate ignores everything outside of attribute expressions, treating it as just text to spit out when you call StringTemplate.toString().

    // [ON UPDATE {RESTRICT | CASCADE | SET NULL | NO ACTION}]

    final StringTemplate fkst = new StringTemplate(fkTemplateStr);
