zx::result<> AddJob (JobTarget && job)

Add `job` into top level set of jobs in the tree.

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

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

Defined at line 382 of file ../../src/performance/cpu_profiler/targets.cc

zx::result<> AddThread (zx_koid_t pid, ThreadTarget && thread)

Add `thread` into the tree as a child to the process specified by `pid` with no parent job

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

ZX_ERR_NOT_FOUND if there is no process matching `pid`

ZX_ERR_ALREADY_EXISTS if there is already an existing thread at the location

Defined at line 435 of file ../../src/performance/cpu_profiler/targets.cc

zx::result<> RemoveThread (zx_koid_t pid, zx_koid_t tid)

Defined at line 439 of file ../../src/performance/cpu_profiler/targets.cc

zx::result<> AddProcess (ProcessTarget && process)

Add `process` into the job tree as a process with no parent job

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

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

Defined at line 400 of file ../../src/performance/cpu_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 job 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<> RemoveThread (std::span<const zx_koid_t> job_path, zx_koid_t pid, zx_koid_t tid)

Defined at line 462 of file ../../src/performance/cpu_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 the job specified by `job_path` in the process

`pid`

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

Defined at line 443 of file ../../src/performance/cpu_profiler/targets.cc

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

Add `process` into the job tree as a child in the job 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 thread at the location with the same tid

Defined at line 404 of file ../../src/performance/cpu_profiler/targets.cc

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

Search `pid` as a ProcessTarget from the job tree indexed by `job_path`.

ZX_ERR_NOT_FOUND if there is no matching job_path and pid

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

Call `f` on each Job in the TargetTree. The order each job is visited is unspecified. If `f`

returns an error, the function will short circuit and immediately return the error code without

visiting any remaining jobs.

Defined at line 486 of file ../../src/performance/cpu_profiler/targets.cc

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

Call `f` on each top level unparented process as well as every process in each added job. The

order each process is visited is unspecified. If `f` returns an error, the function will short

circuit and immediately return the error code without visiting any remaining processes.

std::optional<std::string_view> GetProcessName (zx_koid_t pid)

Search for the name of the process specified by `pid`.

Defined at line 517 of file ../../src/performance/cpu_profiler/targets.cc

std::optional<std::string_view> GetThreadName (zx_koid_t tid)

Search for the name of the thread specified by `tid`.
