		size_t	toOffset,
		size_t	toStride,
		size_t	count
	)

Copy a subarray from one array to another.

Warning: The two arrays must have the same introspection interface.

Parameters

pvFrom	The source array.
fromOffset	The offset in the source.
fromStride	The interval between elements in pvFrom.
pvTo	The destination array.
toOffset	The offset in the destination.
toStride	The interval between elements in pvTo.
count	The total number of elements to copy from pvFrom to pvTo.

◆ createRequest()

epicsShareExtern PVStructure::shared_pointer epics::pvData::createRequest ( std::string const & request )

Parse and build pvRequest structure.

request the Request string to be parsed. eg. "field(value)"

Returns: The resulting strucuture. Never NULL

Exceptions

std::exception for various parsing errors

◆ deserializeFromBuffer()

void epicsShareFunc epics::pvData::deserializeFromBuffer	(	Serializable *	S,
		ByteBuffer &	in
	)

deserializeFromBuffer Deserialize into S from provided vector

Parameters

S	A Serializeable object. The current contents will be replaced
in	The input buffer (byte order of this buffer is used)

Exceptions

std::logic_error if input buffer is too small. State of S is then undefined.

◆ deserializeFromVector()

void epics::pvData::deserializeFromVector	(	Serializable *	S,
		int	byteOrder,
		const std::vector< epicsUInt8 > &	in
	)

inline

deserializeFromBuffer Deserialize into S from provided vector

Parameters

S	A Serializeable object. The current contents will be replaced
byteOrder	Byte order to write (EPICS_ENDIAN_LITTLE or EPICS_ENDIAN_BIG)
in	The input vector

Exceptions

std::logic_error if input buffer is too small. State of S is then undefined.

Definition at line 190 of file serialize.h.

◆ getFieldCreate()

const FieldCreatePtr& epics::pvData::getFieldCreate ( )

inline

Get the single class that implements FieldCreate,

Returns: The fieldCreate factory.

Definition at line 1416 of file pvIntrospect.h.

◆ serializeToVector()

void epicsShareFunc epics::pvData::serializeToVector	(	const Serializable *	S,
		int	byteOrder,
		std::vector< epicsUInt8 > &	out
	)

Push serialize and append to the provided byte vector. No caching is done. Only complete serialization.

Parameters

S	A Serializable object
byteOrder	Byte order to write (EPICS_ENDIAN_LITTLE or EPICS_ENDIAN_BIG)
out	The output vector. Results are appended

◆ swap()

template<typename T >

T epics::pvData::swap ( T val )

inline

Unconditional byte order swap. defined for integer and floating point types
