Function Documentation

◆ parseJSON() [1/3]

PVStructure::shared_pointer epics::pvData::parseJSON ( std::istream & strm )

Parse JSON text into a PVStructure

Restrictions:

Top level must be {} dict/object
field values must be number, string, array, or dict/object
array values must be number or string

◆ parseJSON() [2/3]

void epics::pvData::parseJSON	(	std::istream &	strm,
		const PVField::shared_pointer &	dest,
		BitSet *	assigned = 0 )

inline

Definition at line 110 of file json.h.

◆ parseJSON() [3/3]

void epics::pvData::parseJSON	(	std::istream &	strm,
		PVField &	dest,
		BitSet *	assigned = 0 )

Parse JSON and store into the provided PVStructure.

Restrictions:

array of union not supported
Only scalar value assigned to union

Parameters

strm	Read JSON text from stream
dest	Store in fields of this structure
assigned	Which fields of dest were assigned. (Optional)

Exceptions

std::runtime_error on failure. dest and assigned may be modified.

Version: Overload added after 7.0.0

◆ printJSON() [1/3]

void epics::pvData::printJSON	(	std::ostream &	strm,
		const PVField &	val,
		const JSONPrintOptions &	opts = JSONPrintOptions() )

Print PVField as JSON

Version: Overload added after 7.0.0

◆ printJSON() [2/3]

void epics::pvData::printJSON	(	std::ostream &	strm,
		const PVField::const_shared_pointer &	val,
		const JSONPrintOptions &	opts = JSONPrintOptions() )

inline

Definition at line 72 of file json.h.

◆ printJSON() [3/3]

void epics::pvData::printJSON	(	std::ostream &	strm,
		const PVStructure &	val,
		const BitSet &	mask,
		const JSONPrintOptions &	opts = JSONPrintOptions() )

Print PVStructure as JSON

'mask' selects those fields which will be printed.

Version: Overload added after 7.0.0

◆ yajl_parse_helper()

bool epics::pvData::yajl_parse_helper	(	std::istream &	src,
		yajl_handle	handle )

Wrapper around yajl_parse()

Parse entire input stream. Errors if extranious non-whitespace found after the point were parsing completes.
