Add SpireMethod patch in ClassPatchInfo for more convenient to adding methods to classes.

After add this feature, you can add a method to a class like this:

@SpirePatch(
        clz = RunicDome.class,
        method = SpirePatch.CLASS
)
public static class PatchRunicDome {
    //this will add onSpawnMonster(AbstractMonster) method to RunicDome
    @SpireMethod(returnType = void.class)
    public static void onSpawnMonster(AbstractRelic runicDome, AbstractMonster monster) {
        runicDome.flash();
        AbstractDungeon.actionManager.addToBottom(new RelicAboveCreatureAction(monster, runicDome));
    }
}

If another mod has already added this method, the method body will insert into the existing method.

@SpirePatch(
        clz = RunicDome.class,
        method = SpirePatch.CLASS
)
public static class TestConflict {
    private static final AbstractRelic mask = new CultistMask();

    @SpireMethod(returnType = void.class, onConflict = SpireMethod.PREFIX)
    public static void onSpawnMonster(AbstractRelic runicDome, AbstractMonster monster) {
        AbstractDungeon.actionManager.addToBottom(new RelicAboveCreatureAction(AbstractDungeon.player, runicDome));
        AbstractDungeon.actionManager.addToBottom(new SFXAction("VO_CULTIST_1A"));
        AbstractDungeon.actionManager.addToBottom(new TalkAction(true, mask.DESCRIPTIONS[1], 1.0F, 2.0F));
    }
}

I have been tested and it works.

You can add a method with return value to a class like this:

@SpirePatch(
        clz = Orichalcum.class,
        method = SpirePatch.CLASS
)
public static class TestReturnValue {
    @SpireMethod(returnType = float.class)
    public static void atDamageModify(AbstractRelic orichalcum, Object[] _retVal, float damage, AbstractCard c) {
        _retVal[0] = c.hasTag(AbstractCard.CardTags.STRIKE) ? damage + 3.0F : damage;
    }
}

@SpirePatch(
        clz = Orichalcum.class,
        method = SpirePatch.CLASS
)
public static class TestConflictWithReturnValue {
    @SpireMethod(returnType = float.class, onConflict = SpireMethod.PREFIX)
    public static void atDamageModify(AbstractRelic orichalcum, Object[] _retVal, float damage, AbstractCard c) {
        _retVal[0] = damage;
    }
}
