Interface IThreadOnCpuProvider

public interface IThreadOnCpuProvider
Interface to be implemented by analyses who has information about the thread running on a CPU at a given time. NOTE to developers: this interface is used with the composite host model but won't be necessary anymore once the analyses populate the model directly.

  • Method Details

    • getThreadOnCpuAtTime

      default @Nullable Integer getThreadOnCpuAtTime(int cpu, long time)
      Gets the current thread ID on a given CPU for a given time
      Parameters:
      cpu - the CPU
      time - the time in nanoseconds
      Returns:
      the current TID at the time on the CPU or null if not known

    • getThreadOnCpuAtTime

      @Nullable Integer getThreadOnCpuAtTime(int cpu, long time, boolean block)
      Gets the current thread ID on a given CPU for a given time, but may blocks if the answer is not available yet but may come later
      Parameters:
      cpu - the CPU
      time - the time in nanoseconds
      block - If true, the method will block until the providers have the data available.
      Returns:
      the current TID at the time on the CPU or null if not known
