View Source Playwright.SDK.Channel.Catalog (playwright v1.44.0-alpha.4)

Provides storage and management of ChannelOwner instances.

Catalog implements GenServer to maintain state, while domain logic is expected to be handled within caller modules such as Playwright.SDK.Channel.

put(catalog, resource)

Adds a resource to the Catalog, keyed on :guid.

rm_r(catalog, guid)

Functions

all(catalog)

child_spec(init_arg)

See Supervisor.

get(catalog, guid, options \\ %{})

@spec get(pid(), binary(), map()) ::
  struct() | {:error, Playwright.SDK.Channel.Error.t()}

Retrieves a resource from the Catalog by its param: guid.

If the resource is already present in the Catalog that resource is returned directly. The desired resource might not yet be in the Catalog, in which case the request will be considered as "awaiting". An awaiting request will later receive a response, when the Catalog entry is made, or will time out.

Returns

resource
{:error, error}

Arguments

key/name	type		description
`catalog`	param	`pid()`	PID for the Catalog server
`guid`	param	`binary()`	GUID to look up
`:timeout`	option	`float()`	Maximum time to wait, in milliseconds. Defaults to `30_000` (30 seconds).

list(catalog, filter)

@spec list(pid(), map()) :: [struct()]

Returns a List of resources matching the provided "filter".

Returns

[resource]
[]

Arguments

key/name	type		description
`catalog`	param	`pid()`	PID for the Catalog server
`filter`	param	`map()`	Attributes for filtering

put(catalog, resource)

@spec put(
  pid(),
  struct()
) :: struct()

Adds a resource to the Catalog, keyed on :guid.

Returns

resource (the same as provided)

Arguments

key/name	type		description
`catalog`	param	`pid()`	PID for the Catalog server
`resource`	param	`struct()`	The resource to store

rm_r(catalog, guid)

@spec rm_r(pid(), binary()) :: :ok

Removes a resource from the Catalog, along with its legacy.

Returns

:ok

Arguments

key/name	type		description
`catalog`	param	`pid()`	PID for the Catalog server
`guid`	param	`binary()`	GUID for the "parent"

start_link(root)

@spec start_link(map()) :: {:ok, pid()}

Starts a Playwright.SDK.Channel.Catalog linked to the current process with the given "root" resource.

Return Values

If the Catalog is successfully created and initialized, the function returns {:ok, pid}, where pid is the PID of the running Catalog server.

Arguments

key/name	type		description
`root`	param	`map()`	The root resource for items in the `Catalog`. Provides the `Session` for its descendants
