Examples of org.apache.cayenne.exp.parser.ASTTrue

org.apache.cayenne.exp.parser.ASTTrue
Boolean true expression element Notice that there is one ASTTrue and one ASTFalse instead of a ASTBoolean with a Boolean value. The main reason for doing this is that a common ASTBoolean will have operand count of 1 and that will default to a prepared statmenet like " where ? and (...)", but we only need " where true and (...)". @see ASTFalse @since 3.0

     * A convenience shortcut for boolean true expression.
