Detailed Description

This class represents a boolean expression over an array of arguments.

This is particularly useful for the $nor operator. When converted to BSON, this class produces an expression {$op: [{arg1}, {arg2}, ...]}

Constructor & Destructor Documentation

template<typename List >

constexpr mangrove::boolean_list_expr< List >::boolean_list_expr	(	const List	args,
		const char *	op
	)

inline

Constructs a boolean expression from a list of sub-expressions, and a certain operator.

Parameters

args	An expression list of boolean conditions.
op	The operator of the expression, e.g. AND or OR.

template<typename List >

void mangrove::boolean_list_expr< List >::append_to_bson	(	bsoncxx::builder::core &	builder,
		bool	wrap = `false`
	)		const

inline

Appends this query to a BSON core builder as a key-value pair "$op: [{lhs}, {rhs}]".

Parameters

builder	A basic BSON core builder.
wrap	Whether to wrap this expression inside a document.
