shared_name: Extract Shared Memory Name

In mori: Shared Memory for R Objects

Extract Shared Memory Name

Description

Extract the shared memory name from a shared object. This name can be passed to map_shared() to open the same region in another process.

Usage

shared_name(x)

Arguments

x	a shared object as returned by share() or map_shared().

Value

A character string identifying the shared object, or NULL if x is not a shared object. For a sub-list or element extracted from a shared list, the string carries a bracketed 1-based index path (e.g. "/mori_abc_1[2,3]"). map_shared() accepts both forms; the path-qualified form returns the addressed sub-object directly. The underlying shared memory region name is the prefix before [ and is recoverable via ⁠sub("\\[.*$", "", shared_name(x))⁠.

See Also

map_shared() to open a shared region by name.

Examples

x <- share(1:100)
shared_name(x)

# A sub-object extracted from a shared list carries a bracketed index path:
lst <- share(list(a = 1:3, b = letters))
shared_name(lst[[2]])
