Member Function Documentation

◆ operator=()

template<class T >

SubObject& lely::canopen::BasicMaster::SubObject::operator= ( T && value )

inline

Sets the value of the sub-object.

Parameters

value the value to be written.

Exceptions

lely::canopen::SdoError if the sub-object does not exist or the type does not match.

See also: Write()

Definition at line 77 of file master.hpp.

◆ operator T()

template<class T >

lely::canopen::BasicMaster::SubObject::operator T ( ) const

inline

Returns the value of the sub-object by submitting an SDO upload request to the local object dictionary.

Exceptions

lely::canopen::SdoError on error.

See also: Read()

Definition at line 91 of file master.hpp.

◆ Read() [1/2]

template<class T >

T lely::canopen::BasicMaster::SubObject::Read ( ) const

inline

Reads the value of the sub-object by submitting an SDO upload request to the local object dictionary.

Returns: the result of the SDO request.

Exceptions

lely::canopen::SdoError on error.

See also: Device::Read(uint16_t idx, uint8_t subidx) const

Definition at line 107 of file master.hpp.

◆ Read() [2/2]

template<class T >

T lely::canopen::BasicMaster::SubObject::Read ( ::std::error_code & ec ) const

inline

Reads the value of the sub-object by submitting an SDO upload request to the local object dictionary.

Parameters

ec	on error, the SDO abort code is stored in ec.

Returns: the result of the SDO request, or an empty value on error.

See also: Device::Read(uint16_t idx, uint8_t subidx, ::std::error_code& ec) const

Definition at line 124 of file master.hpp.

◆ Write() [1/4]

template<class T >

void lely::canopen::BasicMaster::SubObject::Write ( T && value )

inline

Writes a value to the sub-object by submitting an SDO download request to the local object dictionary.

Parameters

value the value to be written.

Exceptions

lely::canopen::SdoError on error.

See also: Device::Write(uint16_t idx, uint8_t subidx, T&& value)

Definition at line 140 of file master.hpp.

◆ Write() [2/4]

template<class T >

void lely::canopen::BasicMaster::SubObject::Write	(	T &&	value,
		::std::error_code &	ec
	)

inline

Writes a value to the sub-object by submitting an SDO download request to the local object dictionary.

Parameters

value	the value to be written.
ec	on error, the SDO abort code is stored in ec.

See also: Device::Write(uint16_t idx, uint8_t subidx, T value, ::std::error_code& ec), Device::Write(uint16_t idx, uint8_t subidx, const T& value, ::std::error_code& ec), Device::Write(uint16_t idx, uint8_t subidx, const char* value, ::std::error_code& ec), Device::Write(uint16_t idx, uint8_t subidx, const char16_t* value, ::std::error_code& ec)

Definition at line 159 of file master.hpp.

◆ Write() [3/4]

void lely::canopen::BasicMaster::SubObject::Write	(	const void *	p,
		::std::size_t	n
	)

inline

Writes an OCTET_STRING or DOMAIN value to the sub-object by submitting an SDO download request to the local object dictionary.

Parameters

p	a pointer to the bytes to be written.
n	the number of bytes to write.

Exceptions

lely::canopen::SdoError on error.

See also: Device::Write(uint16_t idx, uint8_t subidx, const void* p, ::std::size_t n)

Definition at line 176 of file master.hpp.

◆ Write() [4/4]

void lely::canopen::BasicMaster::SubObject::Write	(	const void *	p,
		::std::size_t	n,
		::std::error_code &	ec
	)

inline

Writes an OCTET_STRING or DOMAIN value to the sub-object by submitting an SDO download request to the local object dictionary.

Parameters

p	a pointer to the bytes to be written.
n	the number of bytes to write.
ec	on error, the SDO abort code is stored in ec.

See also: Device::Write(uint16_t idx, uint8_t subidx, const void* p, ::std::size_t n, ::std::error_code& ec)
