java.lang.Object

org.luaj.vm2.lib.jse.CoerceJavaToLua

public class CoerceJavaToLua
extends Object

Helper class to coerce values from Java to lua within the luajava library.

This class is primarily used by the LuajavaLib, but can also be used directly when working with Java/lua bindings.

To coerce scalar types, the various, generally the valueOf(type) methods on LuaValue may be used:

• LuaValue.valueOf(boolean)
• LuaValue.valueOf(byte[])
• LuaValue.valueOf(double)
• LuaValue.valueOf(int)
• LuaValue.valueOf(String)

To coerce arrays of objects and lists, the listOf(..) and tableOf(...) methods on LuaValue may be used:

• LuaValue.listOf(LuaValue[])
• LuaValue.listOf(LuaValue[], org.luaj.vm2.Varargs)
• LuaValue.tableOf(LuaValue[])
• LuaValue.tableOf(LuaValue[], LuaValue[], org.luaj.vm2.Varargs)

The method coerce(Object) looks as the type and dimesioning of the argument and tries to guess the best fit for corrsponding lua scalar, table, or table of tables.

coerce

public static LuaValue coerce(Object o)

Coerse a Java object to a corresponding lua value.

Integral types boolean, byte, char, and int will become LuaInteger; long, float, and double will become LuaDouble; String and byte[] will become LuaString; types inheriting from LuaValue will be returned without coercion; other types will become LuaUserdata.

参数:

o - Java object needing conversion

返回:

LuaValue corresponding to the supplied Java value.
