public final class JavaMethod
extends JavaMember

LuaValue that represents a Java method.

Can be invoked via call(LuaValue...) and related methods.

This class is not used directly. It is returned by calls to calls to JavaInstance.get(LuaValue key) when a method is named.

getJavaMethod

public Method getJavaMethod()

call

public LuaValue call()

Description copied from class: LuaValue

Call this with 0 arguments, including metatag processing, and return only the first return value.

If this is a LuaFunction, call it, and return only its first return value, dropping any others. Otherwise, look for the LuaValue.CALL metatag and call that.

If the return value is a Varargs, only the 1st value will be returned. To get multiple values, use LuaValue.invoke() instead.

To call this as a method call, use LuaValue.method(LuaValue) instead.

Overrides:

call in class VarArgFunction

Returns:

First return value (this()), or LuaValue.NIL if there were none.

See Also:

• LuaValue.call(LuaValue)
• LuaValue.call(LuaValue,LuaValue)
• LuaValue.call(LuaValue, LuaValue, LuaValue)
• LuaValue.invoke()
• LuaValue.method(String)
• LuaValue.method(LuaValue)

call

public LuaValue call(LuaValue arg)

Description copied from class: LuaValue

Call this with 1 argument, including metatag processing, and return only the first return value.

If this is a LuaFunction, call it, and return only its first return value, dropping any others. Otherwise, look for the LuaValue.CALL metatag and call that.

If the return value is a Varargs, only the 1st value will be returned. To get multiple values, use LuaValue.invoke() instead.

To call this as a method call, use LuaValue.method(LuaValue) instead.

Overrides:

call in class VarArgFunction

Parameters:

arg - First argument to supply to the called function

Returns:

First return value (this(arg)), or LuaValue.NIL if there were none.

• LuaValue.call(LuaValue,LuaValue)
• LuaValue.call(LuaValue, LuaValue, LuaValue)

call

public LuaValue call(LuaValue arg1,
 LuaValue arg2)

Description copied from class: LuaValue

Call this with 2 arguments, including metatag processing, and return only the first return value.

If this is a LuaFunction, call it, and return only its first return value, dropping any others. Otherwise, look for the LuaValue.CALL metatag and call that.

If the return value is a Varargs, only the 1st value will be returned. To get multiple values, use LuaValue.invoke() instead.

To call this as a method call, use LuaValue.method(LuaValue) instead.

Overrides:

call in class VarArgFunction

Parameters:

arg1 - First argument to supply to the called function

arg2 - Second argument to supply to the called function

Returns:

First return value (this(arg1,arg2)), or LuaValue.NIL if there were none.

call

public LuaValue call(LuaValue arg1,
 LuaValue arg2,
 LuaValue arg3)

Description copied from class: LuaValue

Call this with 3 arguments, including metatag processing, and return only the first return value.

If this is a LuaFunction, call it, and return only its first return value, dropping any others. Otherwise, look for the LuaValue.CALL metatag and call that.

If the return value is a Varargs, only the 1st value will be returned. To get multiple values, use LuaValue.invoke() instead.

To call this as a method call, use LuaValue.method(LuaValue) instead.

Overrides:

call in class VarArgFunction

Parameters:

arg1 - First argument to supply to the called function

arg2 - Second argument to supply to the called function

arg3 - Second argument to supply to the called function

Returns:

First return value (this(arg1,arg2,arg3)), or LuaValue.NIL if there were none.

invoke

public Varargs invoke(Varargs args)

Description copied from class: VarArgFunction

Subclass responsibility. May not have expected behavior for tail calls. Should not be used if: - function has a possibility of returning a TailcallVarargs

Overrides:

invoke in class VarArgFunction

Parameters:

args - the arguments to the function call.
