* Long live Qt5 meta-object method/property descriptorsKent Hansen2012-02-291-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit introduces two significant changes to the meta-object data format: 1) Meta-type information (QMetaType type/name) information is stored directly in the meta-data for both properties and methods; 2) The original signature (string) of a method is no longer stored in the meta-data, since it can be reconstructed from the method name and parameter type info. The motivation for this change is to enable direct access to method names and type information (avoiding string-based lookup for types if possible), since that's typically the information language bindings (e.g. QML) need. (moc already had all the desired information about methods, but it threw it away!) This change keeps support for the older (6 and below) meta-object revisions, but the support will be removed after a short grace period. The following public QMetaMethod functions have been added: name() : QByteArray returnType() : int parameterCount() : int parameterType(int index) : int The following internal QMetaMethod function has been added: getParameterTypes(int *types) : void This commit extends the meta-method data to include explicit type/name data for methods. The new data follows the existing (5-word) method descriptors in the meta-data. The method descriptor format was modified to enable this. First, the descriptor now contains the meta-data index where the method's type/name information can be found. Second, the descriptor contains the number of parameters. Third, the descriptor has a reference to the name of the method, not the full signature. Each entry of a method's type/name array contains either the type id (if it could be determined at meta-object definition time), or a reference to the name of the type (so that the type id can be resolved at runtime). Lastly, instead of storing the method parameter names as a comma-separated list that needs to be parsed at runtime (which was how it was done prior to this commit), the names are now stored as separate entries in the meta-object string table, and their indexes are stored immediately after the method type info array. Hence, parameter names can be queried through the public API without parsing/allocating/copying, too.

* Change the representation of meta-object string dataKent Hansen2012-02-291-1/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Up to and including meta-object revision 6, string data have been stored as 0-terminated C-style strings, that were made directly accessible as const char pointers through the public API (QMetaMethod and friends). This commit changes moc to generate an array of QByteArrayData instead, and adapts the QObject kernel accordingly. Generating an array of QByteArrayData (byte array literals) means that the strings can now be returned from public (or private) API as QByteArrays, rather than const char *, with zero allocation or copying. Also, the string length is now computed at compile time (it's part of the QByteArrayData). This commit only changes the internal representation, and does not affect existing public API. The actual (C) string data that the byte array literals reference still consists of zero-terminated strings. The benefit of having the QByteArrayData array will only become apparent in the upcoming meta-object data format change, which changes the format of property and method descriptors. Support for the old meta-object string data format was kept; the codepaths for old revisions (6 and below) will be removed in a separate commit, once all the other meta-object changes are done and affected code has been adapted accordingly.

| | | | | | | | | | | | | | moc can now embed meta information about the plugin inside the plugin itself. This information can be queried by Qt without having to load the plugin. Source compatibility with the old plugin loading mechanism is still there, but will be removed before Qt 5.0.
