How to find type of an hardcoded ID in JAVA

Question

In SFDC we have methods to identify the type of ID

Sample code:

Id idType = '50011000002ZXX';               
Schema.sObjectType entityType = idType.getSObjectType();  
System.debug('ID belongs to:'+entityType); //ID belongs to: Case

Can we make use of the above methods in Java code using an API? How would one access these methods?

Answer 1

You can do this with either the SOAP or REST based versions of the Tooling API via EntityDefinition. There is a KeyPrefix field you can search on to find the specific match.

E.g.

Select Id,QualifiedApiName,KeyPrefix from EntityDefinition where KeyPrefix = '001'    

Answer 2

You need to check the generated code you are using to connect to Salesforce to determine if the Id type is a basic string type, or an actual type with methods associated with it.

From Metdata API Field Types:

"Note that most Web services tools, including .NET andWSC, map the ID simple type defined in the API WSDL (Enterprise or Partner) to a string. However, other tools generate a specific ID class to represent the ID simple type. Please consult your Web services toolkit documentation for more information."
