Entity property of type Edm.SByte breaks edmx parsing #139

Closed GoogleCodeExporter closed 8 years ago

GoogleCodeExporter commented 8 years ago 
What steps will reproduce the problem?

1. Consume a service which defines an entity type property of type Edm.SByte.
2. The official SAP Netweaver Gateway demo service can be used to reproduce the 
problem: 
http://gw.esworkplace.sap.com/sap/opu/sdata/iwcnt/contact/$metadata

What is the expected output? What do you see instead?

Parsing the entity data model throws an exception:

What version of the product are you using? On what operating system?

0.5 / 0.6-SNAPSHOT

Please provide any additional information below.

The Edm.SByte simple type (contains a signed 8-bit integer value) is currently 
not supported in odata4j. OData4j only defines Edm.Byte and maps it to 
java.lang.Byte (Edm.Byte is defined as unsigned 8-bit integer value).

As I have to consume SAP Netweaver Gateway services, I defined a new SByte 
member in EdmSimpleType as EdmSimpleType<Byte>. While that is more or less a 
workaround which maps SByte to java.lang.Byte, 
it allows consuming data services with SByte properties.

Thanks, I'll take a look.

Perhaps we should have java.lang.Byte (signed) map exclusively to Edm.SByte, 
and introduce a new UnsignedByte type (no jdk equiv) to map to Edm.Byte.

Yes, that would be the best solution. I just needed a quick fix when I ran into 
this issue and came up with this patch. I would like to implement a new 
UnsignedByte type as soon as I have the time and will send you a new patch (or 
commit directly if it is okay for you).

Regards,
Manuel

Integrated patch as revision d9e08c6dc731

Leaving this issue open until we address unsigned bytes.

Added UnsignedByte type and mapped to Edm.Byte, should be all set.
