Exception list structure

The following figure shows one way in which to construct an exception list.

ExceptionList {
    RecoverableException = {                 1
        File     = 'f:/build/argo/src/DataFlowEngine/ImbDataFlowNode.cpp'
        Line     = 538
        Function = 'ImbDataFlowNode::createExceptionList'
        Type     = 'ComIbmComputeNode'
        Name     = '0e416632-de00-0000-0080-bdb4d59524d5'
        Label    = 'mf1.Compute1'
        Text     = 'Node throwing exception'
        Catalog  = 'WebSphere Message Broker2'
        Severity = 3
        Number   = 2230
        RecoverableException = {               2
            File     = 'f:/build/argo/src/DataFlowEngine/ImbRdlBinaryExpression.cpp'
            Line     = 231
            Function = 'ImbRdlBinaryExpression::scalarEvaluate'
            Type     = 'ComIbmComputeNode'
            Name     = '0e416632-de00-0000-0080-bdb4d59524d5'
            Label    = 'mf1.Compute1'
            Text     = 'error evaluating expression'
            Catalog  = 'WebSphere Message Broker2'
            Severity = 2
            Number   = 2439
            Insert   = {
               Type = 2
               Text = '2'
            }
            Insert   = {
               Type = 2
               Text = '30'
            }
            RecoverableException = {             3
                File     = 'f:/build/argo/src/DataFlowEngine/ImbRdlValueOperations.cpp'
                Line     = 257
                Function = 'intDivideInt'
                Type     = 'ComIbmComputeNode'
                Name     = '0e416632-de00-0000-0080-bdb4d59524d5'
                Label    = 'mf1.Compute1'
                Text     = 'Divide by zero calculating '%1 / %2''
                Catalog  = 'WebSphere Message Broker2'
                Severity = 2
                Number   = 2450
                Insert   = }
                   Type = 5
                   Text = '100 / 0'
                }
            }
        }
    }
}
 
Notes:
  1. The first exception description 1 is a child of the root. This identifies error number 2230, indicating that an exception has been thrown. The node that has thrown the exception is also identified (mf1.Compute1).
  2. Exception description 2 is a child of the first exception description 1. This identifies error number 2439.
  3. Exception description 3 is a child of the second exception description 2. This identifies error number 2450, which indicates that the node has attempted to divide by zero.
