    • getTraceConfiguration

      TraceConfiguration getTraceConfiguration()
      Returns the trace configuration for this context
      Returns:
      the trace configuration. It may be null.

    • setTraceConfiguration

      void setTraceConfiguration(TraceConfiguration traceConfiguration)
      Sets the trace configuration of this context. A null can be passes. In this case there will be no trace.
      Parameters:
      traceConfiguration - the trace configuration. It may be null.

    • getTrace

      Trace getTrace()
      Returns the trace of execution. It may be null if the trace configuration is null.
      Returns:
      the trace of execution. It may be null if the trace configuration is null.

    • getExecutionId

      String getExecutionId()
      Returns the execution identifier.
      Returns:
      the execution identifier.

    • get

      Object get(String key)
      Returns a value stored in the runContext
      Parameters:
      key - the key whose associated value is to be returned*
      Returns:
      the value to which the specified key is mapped, or null if this map contains no mapping for the key

    • put

      Object put(String key, Object value)
      Stores a key value pair
      Parameters:
      key - key with which the specified value is to be associated
      value - value to be associated with the specified key
      Returns:
      the previous value associated with key, or null if there was no mapping for key.

    • computeIfAbsent

      default Object computeIfAbsent(String key, Function<String,Object> mappingFunction)
      Strores a key value pair if the value is absent (or null)
      Parameters:
      key - key with which the specified value is to be associated
      mappingFunction - the mapping function to compute a value
      Returns:
      the previous value or the newly computed value.
