Public Methods

zx::result<> ForEachProcess (const fit::function<zx::result<> (std::span<const zx_koid_t>, const ProcessTarget &)> & f)

Do a depth first search to call f on each process in the modeled job tree.

Defined at line 28 of file ../../src/performance/experimental/profiler/targets.cc

zx::result<> ForEachJob (const fit::function<zx::result<> (const JobTarget &)> & f)

Do a depth first search to call f on each child job in the modeled job tree.

Defined at line 49 of file ../../src/performance/experimental/profiler/targets.cc

zx::result<> AddJob (std::span<const zx_koid_t> ancestry, JobTarget && job)

Add `job` into the job tree as a child to the nested jobs specified by `ancestry`.

Returns zx::ok if the job was successfully added,

ZX_ERR_NOT_FOUND if there is no matching ancestry

ZX_ERR_ALREADY_EXISTS if there is already an existing job at the location with the same job_id

Note: `ancestry` is the jobs that `job` will be placed under and does not include the job_id of

`job` itself.

zx::result<> AddProcess (std::span<const zx_koid_t> job_path, ProcessTarget && process)

Add `process` into the job tree as a child to the job specified by `job_path`

Returns zx::ok if the process was successfully added,

ZX_ERR_NOT_FOUND if there is no matching job_path

ZX_ERR_ALREADY_EXISTS if there is already an existing process at the location with the same pid

zx::result<ProcessTarget *> GetProcess (std::span<const zx_koid_t> job_path, zx_koid_t pid)

Get `process` from the job tree as a child to the job specified by `job_path`

Returns zx::ok if the process was found,

ZX_ERR_NOT_FOUND if there is no matching job_path or pid

Defined at line 95 of file ../../src/performance/experimental/profiler/targets.cc

zx::result<> AddThread (std::span<const zx_koid_t> job_path, zx_koid_t pid, ThreadTarget && thread)

Add `thread` into the job tree as a child to process in job specified by `pid` and `job_path`.

Returns zx::ok if the thread was successfully added,

ZX_ERR_NOT_FOUND if there is no matching job_path

ZX_ERR_ALREADY_EXISTS if there is already an existing thread at the location with the same tid
