Class expression_filter¶
class expression_filter<T> base¶
template <typename T>
class expression_filter : public filter<T> { … }Filter adapter that wraps an expression containing a placeholder.
constructor expression_filter<T>(expression_handle<T, 1>) ¶
explicit expression_filter(expression_handle<T, 1> filter_expr)Constructs the filter from a placeholder expression handle.
| filter_expr | Expression containing a placeholder to be substituted with the input on each call. |
