Constructor & Destructor Documentation

◆ Json_int()

Json_int::Json_int ( longlong  value)
inlineexplicit

Member Function Documentation

◆ clone()

Json_dom_ptr Json_int::clone ( ) const
inlineoverridevirtual

Make a deep clone.

The ownership of the returned object is henceforth with the caller.

Returns
a cloned Json_dom object.

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()

longlong Json_int::value ( ) const
inline

Return the signed int held by this object.

Returns
the value
