类 CodeBlock

  • public class CodeBlock
extends Object
    A block of code. This can be used to implement very simple parsing for languages that have some concept of code blocks, such as C, Perl, Java, etc. Currently, using CodeBlocks provides a means of remembering where variables are defined, as well as their scopes.
