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 LPrototype compile(java.io.InputStream is,
                                 java.lang.String string)
                          throws java.io.IOException

Utility method to invoke the compiler for an input stream

Throws:

java.io.IOException

compile

public LPrototype 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

LuaErrorException - if there is a syntax error.

newlstr

public LString newlstr(char[] chars,
                       int offset,
                       int len)

newTString

public LString newTString(LString s)

pushfstring

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