Getting the properties for an ODataEntry

Hi,

I have an OData feed.sample code looks like--

ODataFeed odata_feed=
EntityProvider.readFeed(HttpContentType.APPLICATION_XML,entitycontainer.getEntitySet(entitySetName),content_feed,EntityProviderReadProperties.init().build());

for(ODataEntry odata_entry:odata_feed.getEntries())
{
odata_entry.getProperties();
}


odata_entry.getProperties();  gets all the properties corresponding to an
entry.
For each ODataEntry I want to get only certain properties and not all.Is
there any way to do that?

Thanks
Prerna

Hi Prerna,

Have a look into Javadoc:

http://olingo.apache.org/javadoc/odata2/

You will get the information from Interface EdmEntityType.

Greetings,
Stephan

Subject: Re: Getting the properties for an ODataEntry

Hi Stephan,

I have a propertyname as String .I want to check whether that property(Column name) exists in the OData entitySet or not.Is there any direct API for that or we need to get the names of all the properties from an odata entry and then check my string against all the properties of Odata entry?



Thanks
Prerna

Thanks! I have another question.
I came across a method EdmTyped<http://olingo.apache.org/javadoc/odata2/org/apache/olingo/odata2/api/edm/EdmTyped.html> getProperty(String<http://docs.oracle.com/javase/6/docs/api/java/lang/String.html?is-external=true> name) available in Interface EdmStructuralType.Is this method only for metadata part?

Yes. All packages or classes having 'edm' in name are about metadata.

Hi Prerna,

$select is your friend. Just construct a feed uri and then add $select query option where you can list properties to be returned by server:

http://…./SomeFeed?$select=prop1,prop2,prop3
