Member Function Documentation

clone()

virtual std::unique_ptr< value > json::value::clone ( ) const

pure virtual

Implemented in json::array, json::float_number, json::integer_number, json::literal, json::object, and json::string.

References DEBUG_FUNCTION.

Referenced by json::array::clone(), json::object::clone_as_object(), and diagnostics::copy_any_property_bag().

compare()

int value::compare ( const json::value & val_a, const json::value & val_b )

static

A deterministic total ordering for comparing json values, so that we
can e.g. put them in std::map.

This is intended to follow the condition for equality described in
the JSON Schema standard (§4.3, “Instance equality”), as referenced
by SARIF v2.1.0 (§3.7.3 "Array properties with unique values"), but has
the following limitations:
- numbers are supposed to be checked for "the same mathematical value",
but in this implementation int vs float numbers won't compare as equal,
and float number comparison is bitwise
- strings are supposed to be "the same codepoint-for-codepoint", but
this implementation doesn't take into account canonicalization issues.

dump() [1/2]

void value::dump

(

)

const

A convenience function for debugging.
Dump to stderr with formatting, and a trailing newline.  

References dump().

dump() [2/2]

void value::dump	(	FILE *	outf,
		bool	formatted ) const

class json::value.   

Dump this json::value tree to OUTF.

The key/value pairs of json::objects are printed in the order
in which the keys were originally inserted.
