parser::write (5 of 6 overloads)

Parse a buffer containing a complete JSON text.

Synopsis
std::size_t
write(
    char const* data,
    std::size_t size);
Description

This function parses a complete JSON text contained in the specified character buffer. The entire buffer must be consumed; if there are additional characters past the end of the complete JSON text, the parse fails and an error is returned.

Example
parser p;                                       // construct a parser
size_t n = p.write( "[1,2,3]" );                // parse a complete JSON text
assert( n == 7 );                               // all characters consumed
value jv = p.release();                         // take ownership of the value
Complexity

Linear in size.

Exception Safety

Basic guarantee. Calls to memory_resource::allocate may throw. Upon error or exception, subsequent calls will fail until reset is called to parse a new JSON text.

Return Value

The number of characters consumed from the buffer.

Parameters

Name

Description

data

A pointer to a buffer of size characters to parse.

size

The number of characters pointed to by data.
