serializer

A serializer for JSON.

Synopsis

Defined in header <boost/json/serializer.hpp>

class serializer

Member Functions

Name	Description
done	Returns `true` if the serialization is complete.
read	Read the next buffer of serialized JSON.
reset	Reset the serializer for a new element. — Reset the serializer for a new string.
serializer [constructor]	Move constructor (deleted) — Default constructor.
~serializer [destructor]	Destructor.

This class traverses an instance of a library type and emits serialized JSON text by filling in one or more caller-provided buffers. To use, declare a variable and call reset with a pointer to the variable you want to serialize. Then call read over and over until done returns true.

Example

This demonstrates how the serializer may be used to print a JSON value to an output stream.

void print( std::ostream& os, value const& jv)
{
    serializer sr;
    sr.reset( &jv );
    while( ! sr.done() )
    {
        char buf[ 4000 ];
        os << sr.read( buf );
    }
}

The same instance may not be accessed concurrently.
