Implements Json_dom.

is_16bit()

bool Json_int::is_16bit ( ) const

inline

Returns

true if the number can be held by a 16 bit signed integer

is_32bit()

bool Json_int::is_32bit ( ) const

inline

Returns

true if the number can be held by a 32 bit signed integer

json_type()

enum_json_type Json_int::json_type ( ) const

inlineoverridevirtual

Returns

the type corresponding to the actual Json_dom subclass

Implements Json_dom.

value()
