struct LuaTable;
Represents a Lua table.
LuaObject object;
LuaTable sub-types luad.base.LuaObject through this reference.
@trusted T get(T, U...)(U args);
- Parameters
T type of value U args list of keys, where all keys but the last one should result in a table - Returns
- t[k] where t is the table for the second-to-last parameter, and k is the last parameter
- Examples
auto execute = lua.get!LuaFunction("os", "execute"); execute(`echo hello, world!`);
Lookup a value in this table or in a sub-table of this table.
@trusted bool readString(T)(T key, scope void delegate(in char[] str) dg);
- Parameters
T key lookup key void delegate(in char[] str) dg delegate to receive string - Returns
- true if the value for key was a string and passed to dg, false otherwise
- Examples
t[2] = "two"; t.readString(2, str => assert(str == "two"));
Read a string value in this table without making a copy of the string. The read string is passed to dg, and should not be escaped. If the value for key is not a string, dg is not called.
LuaObject opIndex(T...)(T args);
- Examples
auto luapath = lua["package", "path"]; writefln("LUA_PATH:\n%s", luapath);
- See Also
- LuaTable.get
Same as calling get!LuaObject with the same arguments.
@trusted void set(T, U)(T key, U value);
- Parameters
T key key to set U value value for key
Set a key-value pair in this table.
@trusted void opIndexAssign(T, U...)(T value, U args);
- Parameters
T value value to set U args list of keys, where all keys but the last one should result in a table - Returns
- t[k] = value, where t is the table for the second-to-last parameter in args, and k is the last parameter in args
- Examples
lua["string", "empty"] = (in char[] s){ return s.length == 0; }; lua.doString(`assert(string.empty(""))`);
Set a key-value pair this table or in a sub-table of this table.
@trusted T toStruct(T)() if (is(T == struct));
- Parameters
T any struct type - Returns
- Newly created struct
Create struct of type T and fill its members with fields from this table.
Struct fields that are not present in this table are left at their default value.
@trusted void copyTo(T)(ref T s) if (is(T == struct));
- Parameters
T s struct to fill
Fill a struct's members with fields from this table.
@trusted void setMetaTable(ref LuaTable meta);
- Parameters
LuaTable meta new metatable
Set the metatable for this table.
@trusted LuaTable getMetaTable();
- Returns
- A reference to the metatable for this table. The reference is nil if this table has no metatable.
Get the metatable for this table.
@trusted size_t length();
Get the array length of the table.
@trusted int opApply(T)(int delegate(ref T value) dg);
Iterate over the values in this table.
@trusted int opApply(T, U)(int delegate(ref U key, ref T value) dg);
Iterate over the key-value pairs in this table.
