package org.jruby.compiler;
Compiler represents the current state of a compiler and all appropriate transitions and modifications that can be made within it. The methods here begin and end a class for a given compile run, begin and end methods for the script being compiled, set line number information, and generate code for all the basic operations necessary for a script to run. The intent of this interface is to provide a library-neutral set of functions for compiling a given script using any backend or any output format.
public interface ScriptCompiler {
Begin compilation for a script, preparing all necessary context and code to support this script's compiled representation.
    public void startScript(StaticScope scope);
End compilation for the current script, closing all context and structures used for the compilation.
    public void endScript(boolean generateLoadboolean generateMain);
Begin compilation for a method that has the specified number of local variables. The returned value is a token that can be used to end the method later.

    public BodyCompiler startMethod(String rubyNameString javaNameCompilerCallback argsHandlerStaticScope scopeASTInspector inspectorint scopeIndex);
Begin compilation for the root of a script named __file__.

args Arguments to the script, as passed via jitted wrappers
scope The StaticScope for the script
inspector The ASTInspector for the nodes for the script
A new BodyCompiler for the body of the script
    public BodyCompiler startFileMethod(CompilerCallback argsStaticScope scopeASTInspector inspector);
