iOS 12.2

iOS 12.2 has arrived as PR363. It reflects changes apple did. Beside updating API robovm-cocoatouch received following updates:

fixed broken structs in AudioToolBox;
added IntentsUI framework;
added UserNotificationsUI framework;

What’s new in bro-gen

Main change its support for inner and anonymous structures and unions. Previously bro-gen skipped these and it resulted in broken Structures at java side.

Case1: inner structs with member reference

struct StructWithInner {
    int memberA;
    struct {
       int memberB;
    } innerA;
}

will be transformed into following:

public class StructWithInner extends Struct<StructWithInner> {
    @StructMember(0) public native int getMemberA();
    @StructMember(0) public native StructWithInner setMemberA(int memberA);
    @StructMember(1) public native @ByVal StructWithInner$InnerStruct$1 getInnerA();
    @StructMember(1) public native StructWithInner setInnerA(@ByVal StructWithInner$InnerStruct$1 innerA);
}

StructWithInner$InnerStruct$1 has to be configured in yaml to be generated, proper name can be assign there as well.

Case2: anonymous struct

struct StructWithInner {
    int memberA;
    struct {
       int memberB;
    };
}

Anonymous structure are flatten and their member become member of owning struct:

public class StructWithInner extends Struct<StructWithInner> {
    @StructMember(0) public native int getMemberA();
    @StructMember(0) public native StructWithInner setMemberA(int memberA);
    @StructMember(1) public native int getMemberB();
    @StructMember(1) public native StructWithInner setMemberB(int memberB);
}

Case3: anonymous unions

Anonymous unions are not being flatten and is extracted into standalone struct:

struct StructWithInner {
    int memberA;
    union {
       int memberB;
    };
}

StructWithInner$InnerStruct$1 has to be configured in yaml to be generated, proper name can be assign there as well. Also member name autoMember$2 is generated for it, also might be configured in yaml.

public class StructWithInner extends Struct<StructWithInner> {
    @StructMember(0) public native int getMemberA();
    @StructMember(0) public native StructWithInner setMemberA(int memberA);
    @StructMember(1) public native @ByVal StructWithInner$InnerStruct$1 getAutoMember$2();
    @StructMember(1) public native StructWithInner setAutoMember$2(@ByVal StructWithInner$InnerStruct$1 autoMember$2);
}

Case4: when union is owner

When root structure is union – all inner structures are being extracted. Anonymous structures are not being flatten.

union UnionWithInner {
    int memberA;
    struct {
       int memberB;
    };
}

Result:

public class UnionWithInner extends Struct<UnionWithInner> {
    @StructMember(0) public native int getMemberA();
    @StructMember(0) public native UnionWithInner setMemberA(int memberA);
    @StructMember(0) public native @ByVal UnionWithInner$InnerStruct$1 getAutoMember$2();
    @StructMember(0) public native UnionWithInner setAutoMember$2(@ByVal UnionWithInner$InnerStruct$1 autoMember$2);
}

Case5: inner structs that are not members

In example bellow struct Inner is not an anonymous member but structure definition. it is not a subject for member generation.

struct StructWithInner {
    int memberA;
    struct Inner{
       int memberB;
    };
}
