Detailed Description

template<class string_type_ = boost::logging::hold_string_type, class ptr_type = void*>
struct boost::logging::optimize::cache_string_several_str< string_type_, ptr_type >

This holds 3 strings - one for prepend, one for modification, and one for appending.

When you prepend or append, you can also specify an extra argument - an identifier. This identifier uniquely identifies the prepended or appended message.

Afterwards, you can prepend/append only by specifying an identifier - which will identify a previously appended or prepended message

boost::logging::optimize::cache_string_several_str< string_type_, ptr_type >::cache_string_several_str

(

int

reserve_ = 512

)

[inline]

constructs an object

Parameters:

reserve_

[optional, default = 512] When creating the full msg, how much should we reserve?

template<class string_type_ = boost::logging::hold_string_type, class ptr_type = void*>

boost::logging::optimize::cache_string_several_str< string_type_, ptr_type >::cache_string_several_str	(	const string_type &	msg,
		int	reserve_ = 512
	)			[inline]

constructs an object

Parameters:

reserve_

[optional, default = 512] When creating the full msg, how much should we reserve?

(

string_type &

msg

)

[inline]

sets the string with a swap (that is, you pass a non-const refererence, and we do a swap)

[inline]

Specifies the id of the last message
