Interface CallStackSeries.IThreadIdProvider

Enclosing class:
CallStackSeries
public static interface CallStackSeries.IThreadIdProvider
Interface for classes that provide a thread ID at time t for a callstack. The thread ID can be used to calculate extra statistics per thread, for example, the CPU time of each call site.

  • Method Summary

    Modifier and Type
    Method
    Description
    int
    getThreadId(long time)
    Get the ID of callstack thread at a given time
    boolean
    variesInTime()
    Return whether the value returned by this provider is variable through time (ie, each function of a stack may have a different thread ID), or is fixed (ie, all functions in a stack have the same thread ID)

  • Method Details

    • getThreadId

      int getThreadId(long time)
      Get the ID of callstack thread at a given time
      Parameters:
      time - The time of request
      Returns:
      The ID of the thread, or IHostModel.UNKNOWN_TID if unavailable

    • variesInTime

      boolean variesInTime()
      Return whether the value returned by this provider is variable through time (ie, each function of a stack may have a different thread ID), or is fixed (ie, all functions in a stack have the same thread ID)
      Returns:
      If true, the thread ID will be identical for a stack all throughout its life, it can be therefore be used to provider other thread-related information on stack even when there are no function calls.
