Interface CallStack

All Known Implementing Classes:
NoOpCallStack, ThrowableCallStack
public interface CallStack
Strategy for obtaining and printing the current call stack. This is primarily useful for usage tracking so that different JVMs and configurations can use more efficient strategies for obtaining the current call stack depending on metadata needs.
Since:
2.4.3

  • Method Summary

    Modifier and Type
    Method
    Description
    void
    clear()
    Clears the current stack trace snapshot.
    void
    fillInStackTrace()
    Takes a snapshot of the current call stack.
    boolean
    printStackTrace(PrintWriter writer)
    Prints the current stack trace if available to a PrintWriter.

  • Method Details

    • clear

      void clear()
      Clears the current stack trace snapshot. Subsequent calls to printStackTrace(PrintWriter) will be no-ops until another call to fillInStackTrace().

    • fillInStackTrace

      void fillInStackTrace()
      Takes a snapshot of the current call stack. Subsequent calls to printStackTrace(PrintWriter) will print out that stack trace until it is cleared.

    • printStackTrace

      boolean printStackTrace(PrintWriter writer)
      Prints the current stack trace if available to a PrintWriter. The format is undefined and is primarily useful for debugging issues with PooledObject usage in user code.
      Parameters:
      writer - a PrintWriter to write the current stack trace to if available
      Returns:
      true if a stack trace was available to print or false if nothing was printed
