PR1741: Replace pulse audio enums with static longs.
2011-06-16 Denis Lila <dlila@redhat.com>
* Makefile.am: Add ContextEvent to the list of pulse audio classes that
need javah run on them.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/ContextEvent.java
(Type): Remove and replace with...
(UNCONNECTED, CONNECTING, AUTHORIZING, SETTING_NAME, READY, FAILED,
TERMINATED): New static long variables replacing enum Type.
(init_constants): New native method to initialize the above variables.
(checkNativeEnumReturn): Make sure that the input is one of the longs
representing the type of ContextEvent.
(type): Change type from Type to long.
(ContextEvent): Take a long argument, instead of a Type.
(getType): Return a long, not a Type.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/EventLoop.java
(status): Change from int to long.
(native_set_sink_volume): Remove. It was unimplemented in the JNI side.
(getStatus): Return long instead of int.
(update): Replace int argument with long argument. Remove the switch
statement.
(setVolume): Remove. Unused.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/Operation.java
(State): Remove and replace with...
(Running, Done, Cancelled): Static longs, enumerating the possible
operation states.
(init_constants): New native method to initialize the above variables.
(checkNativeOperationState): Make sure that the input is one of the longs
representing the operation state.
(native_get_state): Change return type from int to long.
(getState): Change return type to long; remove switch.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/PulseAudioDataLine.java
Remove the names of enums from the names of constants since most of them
were changed to static longs.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/PulseAudioMixer.java
Same changes as in PulseAudioDataLine.java.
* pulseaudio/src/java/org/classpath/icedtea/pulseaudio/Stream.java
(State): Remove and replace with...
(UNCONNECTED, CREATING, READY, FAILED, TERMINATED): New static long variables
replacing enum Type.
(init_constants): New native method to initialize the above variables.
(checkNativeStreamState): Make sure that the input is one of the longs
representing the kind of StreamState.
(native_pa_stream_get_state): Change the return from int to long.
(getState): Remove the switch.
* pulseaudio/src/native/jni-common.h
(SET_JAVA_STATIC_LONG_FIELD_TO_PA_ENUM): Macro that sets one of the java
static longs to the corresponding pa_constant.
* pulseaudio/src/native/org_classpath_icedtea_pulseaudio_ContextEvent.c
New file.
(SET_CONTEXT_ENUM): Macro that sets the ContextEvent types.
(Java_org_classpath_icedtea_pulseaudio_ContextEvent_init_1constants):
Implementation of ContextEvent.init_constants.
* pulseaudio/src/native/org_classpath_icedtea_pulseaudio_EventLoop.c
(context_change_callback): Change the fourth argument of GetMethodID
to "(J)V" to reflect the change in the signature of EventLoop.update.
* pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Operation.c
(SET_OP_ENUM): Macro that sets the operation types.
(Java_org_classpath_icedtea_pulseaudio_Operation_init_1constants):
Implementation of Operation.init_constants.
(Java_org_classpath_icedtea_pulseaudio_Operation_native_1get_1state):
Change return type to jlong.
* pulseaudio/src/native/org_classpath_icedtea_pulseaudio_Stream.c
(SET_STREAM_ENUM): Macro that sets the stream states.
(Java_org_classpath_icedtea_pulseaudio_Stream_init_1constants):
Implementation of Stream.init_constants.
(Java_org_classpath_icedtea_pulseaudio_Stream_native_1pa_1stream_1get_1state):
Change return type to jlong.
