The acquired connection then can be used to call methods +on remote objects and emit or receive signals. Using the Export method, you can +arrange D-Bus methods calls to be directly translated to method calls on a Go +value. + +Conversion Rules + +For outgoing messages, Go types are automatically converted to the +corresponding D-Bus types. The following types are directly encoded as their +respective D-Bus equivalents: + + Go type | D-Bus type + ------------+----------- + byte | BYTE + bool | BOOLEAN + int16 | INT16 + uint16 | UINT16 + int | INT32 + uint | UINT32 + int32 | INT32 + uint32 | UINT32 + int64 | INT64 + uint64 | UINT64 + float64 | DOUBLE + string | STRING + ObjectPath | OBJECT_PATH + Signature | SIGNATURE + Variant | VARIANT + interface{} | VARIANT + UnixFDIndex | UNIX_FD + +Slices and arrays encode as ARRAYs of their element type. + +Maps encode as DICTs, provided that their key type can be used as a key for +a DICT. + +Structs other than Variant and Signature encode as a STRUCT containing their +exported fields. Fields whose tags contain `dbus:"-"` and unexported fields will +be skipped. + +Pointers encode as the value they're pointed to. + +Types convertible to one of the base types above will be mapped as the +base type. + +Trying to encode any other type or a slice, map or struct containing an +unsupported type will result in an InvalidTypeError. + +For incoming messages, the inverse of these rules are used, with the exception +of STRUCTs. Incoming STRUCTS are represented as a slice of empty interfaces +containing the struct fields in the correct order. The Store function can be +used to convert such values to Go structs. + +Unix FD passing + +Handling Unix file descriptors deserves special mention. To use them, you should +first check that they are supported on a connection by calling SupportsUnixFDs. +If it returns true, all method of Connection will translate messages containing +UnixFD's to messages that are accompanied by the given file descriptors with the +UnixFD values being substituted by the correct indices. Similarly, the indices +of incoming messages are automatically resolved. It shouldn't be necessary to use +UnixFDIndex. + +*/ +package dbus |
