Generic Configuration-based SDK

Generic Configuration-based SDK

When working with the Configuration-based SDK, customer wants to use each class-method pair under "sdk.targets" in a generic way, not individually. To summarize,

Instead of this one:

    sdk:

      targets:

        - match:

            type: class

            name: Organization.services.error

            method: wrapError

          span:

            name: Organization.services.error.wrapError 

            type: ENTRY

            stackDepth: 10

Customer wants this:

    sdk:

      targets:

        - match:

            type: class

            name: Organization.*

            method: *

          span:

            name:Organization.[0,....,n].[0,....,n]

            type: ENTRY|EXIT|INTERMEDIATE

            stackDepth: 10

For example, let there be 100 classes under "Organization". Let each of these 100 classes have 50 methods.

For method [0] of class [0], both ENTRY, EXIT and INTERMEDIATE types will be created and the span name will be "Organization.[0].[0]".

So for the example above (100class*50method*3type) there will be 15000 match blocks. All this will be done by wildcard.

In this cumulative class-method list, there may be some methods that reference NULL. These methods should be indicated in the "javaNullPointerException" error in the agent log. Otherwise customer cannot understand which method is causing problems. In the agent log, at least the method on which line throws the "javaNullPointerException" error or the direct method name should be specified.

Another approach would be as follows, even if "javaNullPointerException" is seen, there should be no problem in reading the YAML, the SDK should ignore this problematic method. Thanks.
