Class record_handle

boost::log::record_handle — A logging record handle class.

Synopsis

// In header: <boost/log/core/record.hpp>


class record_handle {
public:

  // public member functions
  bool operator==(record_handle const &) const;
  bool operator!=(record_handle const &) const;
  bool operator!() const;
  void swap(record_handle &);
  void reset();
  void * get() const;
};

Description

This class is used to identify a log record in calls to the logging core. Consider using the basic_record wrapper class for user-scope needs.

`record_handle` public member functions

```
bool operator==(record_handle const & that) const;
```
Equality comparison

Parameters:

that
Comparand

Returns:
true if both *this and that identify the same log record or do not identify any record, false otherwise.
```
bool operator!=(record_handle const & that) const;
```
Inequality comparison

Parameters:

that
Comparand

Returns:
!(*this == that)
```
bool operator!() const;
```
Conversion to an unspecified boolean type

Inverted conversion to an unspecified boolean type

Returns:
true, if the handle identifies a log record, false, if the handle is not valid

Returns:
false, if the handle identifies a log record, true, if the handle is not valid
```
void swap(record_handle & that);
```
Swaps two handles

Parameters:

that
Another handle to swap with Throws: Nothing
```
void reset();
```
Resets the log record handle. If there are no other handles left, the log record is closed and all resources referenced by the record are released.

Postconditions:
!*this == true
```
void * get() const;
```
Returns a non-NULL pointer if the handle is valid, NULL otherwise.

Returns:	`true`, if the handle identifies a log record, `false`, if the handle is not valid
Returns:	`false`, if the handle identifies a log record, `true`, if the handle is not valid
