Examples with Type com.google.protobuf.Descriptors.FieldDescriptor.Type used on opensource projects

Example 1 with Type

use of com.google.protobuf.Descriptors.FieldDescriptor.Type in project j2objc by google.

the class CompatibilityTest method testFindFieldByNumber.

public void testFindFieldByNumber() throws Exception {
    Descriptor descriptor = TypicalData.Builder.getDescriptor();
    Collection<FieldDescriptor> fields = descriptor.getFields();
    for (FieldDescriptor field : fields) {
        FieldDescriptor.Type type = field.getType();
        int fieldId = field.getNumber();
        switch(fieldId) {
            case 1:
                assertEquals(Type.INT32, type);
                break;
            case 2:
                assertEquals(Type.BYTES, type);
                break;
            case 3:
                assertEquals(Type.ENUM, type);
                break;
        }
        FieldDescriptor result = descriptor.findFieldByNumber(fieldId);
        assertEquals(field.getNumber(), result.getNumber());
        assertEquals(field.getName(), result.getName());
    }
}
