Member Function Documentation

void reset

(

)

All input sources are removed and the parser state is reset to parse a new document.

void reset

(

std::basic_istream< Pt::Char > &

is

)

All previous input is removed and the parser is reset to parse a new document. This is essentially the same as calling reset() followed by addInput().

void setChunkSize

(

std::size_t

n

)

If an JSON element contains more character data than this limit, the content is reported as multiple nodes.
