Member Functions

Name	Description
`MetaInt` [constructor]	Does nothing (`MetaInt` is stateless).
`MetaInt` [constructor]	Convert from a `bsl::true_type`.
`operator bool`	Return `true`. (This operator is conversion operator to `bool`.)

Static Member Functions

Name Description

tag Declared but not defined. Meta-function use only. The tag can be used to recover meta-information from an expression. Example: sizeof(f(expr).tag()) returns a different compile-time value depending on the type of the result of calling the f function but does not actually call the f function or the tag method at run-time. Note that f(expr)::VALUE or sizeof(f(expr)::Type) would be ill-formed and that f(expr).value is not a compile-time expression.

Example: `sizeof(f(expr).tag())` returns a different compile-time value depending on the type of the result of calling the `f` function but does not actually call the `f` function or the `tag` method at run-time. Note that `f(expr)::VALUE` or `sizeof(f(expr)::Type)` would be ill-formed and that `f(expr).value` is not a compile-time expression.
