Detailed Description

Purpose

Provide compatibility for clients using single-level namespace

Deprecated:

Do not use.

Mnemonic

Basic Standard Library System ForWarding Declarations (bslfwd)

Description

Each component of this package provides a code snippet defining a forward reference to a corresponding type within 'bsl' (e.g., 'bslfwd_bslma_allocator' defines a forward reference to the type defined in bslma_allocator ). If 'BSLFWD_BUILDTARGET_BSL_USING_NAMESPACES' is defined, the forward declaration will refer the 'bsl' type in the two-level namespace; otherwise, it will refer to the type in the legacy single-level namespace (e.g., 'bslma::Allocator' versus 'bslma_Allocator', both in the 'BloombergLP' namespace).

The components in this package are provided to provide backward compatibility for existing clients. All new code must be written using the two-level namespace for 'bsl' types.

Hierarchical Synopsis

The 'bslfwd' package currently has 8 components having 2 levels of physical dependency. The list below shows the hierarchical ordering of the components. The order of components within each level is not architecturally significant, just alphabetical.
