Method Detail

install

public static void install()

Install the compiler so that LoadState will first try to use it when handed bytes that are not already a compiled lua chunk.

_assert

protected static void _assert(boolean b)

compile

public static Prototype compile(java.io.InputStream is,
                                java.lang.String name)
                         throws java.io.IOException

Utility method to invoke the compiler for an input stream

Throws:

java.io.IOException

load

public static LuaFunction load(java.io.InputStream is,
                               java.lang.String name,
                               LuaValue env)
                        throws java.io.IOException

Load into a Closure or LuaFunction, with the supplied initial environment

Throws:

java.io.IOException

load

public LuaFunction load(int firstByte,
                        java.io.InputStream stream,
                        java.lang.String name,
                        LuaValue env)
                 throws java.io.IOException

Load into a Closure or LuaFunction, with the supplied initial environment

Specified by:

load in interface LoadState.LuaCompiler

Throws:

java.io.IOException

compile

public Prototype compile(int firstByte,
                         java.io.InputStream stream,
                         java.lang.String name)
                  throws java.io.IOException

Compile source bytes into a LPrototype. Try to compile the file, and return the Prototype on success, or throw LuaErrorException on syntax error or I/O Exception

Specified by:

compile in interface LoadState.LuaCompiler

Parameters:

firstByte - the first byte from the InputStream. This can be read by the client and tested to see if it is already a binary chunk.

stream - InputStream to read from.

name - Name of the chunk

Returns:

null if the first byte indicates it is a binary chunk, a LPrototype instance if it can be compiled, or an exception is thrown if there is an error.

Throws:

java.io.IOException - if an I/O exception occurs

LuaError - if there is a syntax error.

newTString

public LuaString newTString(byte[] bytes,
                            int offset,
                            int len)

pushfstring

public java.lang.String pushfstring(java.lang.String string)

load

public LuaFunction load(Prototype p,
                        java.lang.String filename,
                        LuaValue env)

Description copied from interface: LoadState.LuaCompiler

Load into a LuaFunction given a prototype. May compile into a class, or return a LuaClosure

Specified by:

load in interface LoadState.LuaCompiler

filename - TODO
