org.gnome.gobject.TypeValueTable

All Implemented Interfaces:

Proxy

@Generated("io.github.jwharm.JavaGI")
public class TypeValueTable
extends ProxyInstance

• 'i': Integers, passed as collect_values[].v_int
• 'l': Longs, passed as collect_values[].v_long
• 'd': Doubles, passed as collect_values[].v_double
• 'p': Pointers, passed as collect_values[].v_pointer

It should be noted that for variable argument list construction, ANSI C promotes every type smaller than an integer to an int, and floats to doubles. So for collection of short int or char, 'i' needs to be used, and for collection of floats 'd'. The GTypeValueTable provides the functions required by the GValue implementation, to serve as a container for values of a type.
