Constructor & Destructor Documentation

◆ ManagedBytes() [1/5]

ManagedBytes::ManagedBytes ( )

explicit

Constructor.

No data present.

Definition at line 21 of file ManagedBytes.cpp.

◆ ManagedBytes() [2/5]

ManagedBytes::ManagedBytes ( size_t len )

explicit

Constructor.

Makes a data block of the specified length that will be deleted if this object is destroyed.

Parameters

len	length of data block

Definition at line 30 of file ManagedBytes.cpp.

◆ ManagedBytes() [3/5]

ManagedBytes::ManagedBytes	(	const Bytes &	ext,
		bool	owned = `false`
	)

Constructor.

Represent external data.

Parameters

ext	address and length of data
owned	true if data should be deleted if this object is destroyed

Definition at line 39 of file ManagedBytes.cpp.

◆ ManagedBytes() [4/5]

ManagedBytes::ManagedBytes ( ManagedBytes && other )

noexcept

Move constructor.

Parameters

other the ManagedBytes to be moved

Definition at line 70 of file ManagedBytes.cpp.

◆ ManagedBytes() [5/5]

ManagedBytes::ManagedBytes ( const ManagedBytes & alt )

Copy constructor.

Parameters

alt	the data to copy. If it is "owned" an independent copy is made.

Definition at line 48 of file ManagedBytes.cpp.

◆ ~ManagedBytes()

ManagedBytes::~ManagedBytes ( )

virtual

Destructor.

Definition at line 99 of file ManagedBytes.cpp.

Member Function Documentation

◆ allocate()

void ManagedBytes::allocate ( size_t len )

Makes a data block of the specified length that will be deleted if this object is destroyed.

Parameters

len	length of data block

Definition at line 105 of file ManagedBytes.cpp.

◆ allocateOnNeed()

bool ManagedBytes::allocateOnNeed	(	size_t	neededLen,
		size_t	allocateLen
	)

Definition at line 115 of file ManagedBytes.cpp.

◆ bytes() [1/2]

Bytes& yarp::os::ManagedBytes::bytes ( )

Returns: description of data block associated with this object

◆ bytes() [2/2]

Bytes & ManagedBytes::bytes ( ) const

Returns: description of data block associated with this object (const version)

Definition at line 177 of file ManagedBytes.cpp.

◆ clear()

void ManagedBytes::clear ( )

Disassociate object with any data block (deleting block if appropriate).

Definition at line 164 of file ManagedBytes.cpp.

◆ copy()

void ManagedBytes::copy ( )

Makes sure data block is owned, making a copy if necessary.

Definition at line 132 of file ManagedBytes.cpp.

◆ get() [1/2]

char* yarp::os::ManagedBytes::get ( )

Returns: address of data block

◆ get() [2/2]

char * ManagedBytes::get ( ) const

Returns: address of data block (const version)

Definition at line 154 of file ManagedBytes.cpp.

◆ isOwner()

bool yarp::os::ManagedBytes::isOwner ( ) const

inline

Returns: true iff the managed data block is owned by this object

Definition at line 161 of file ManagedBytes.h.

◆ length()

size_t ManagedBytes::length ( ) const

Returns: length of data block

Definition at line 144 of file ManagedBytes.cpp.

◆ operator=() [1/2]

const ManagedBytes & ManagedBytes::operator= ( const ManagedBytes & alt )

Assignment operator.

Parameters

alt	the data to copy. If it is "owned" an independent copy is made.

Returns: this object

Definition at line 84 of file ManagedBytes.cpp.

◆ operator=() [2/2]

ManagedBytes & ManagedBytes::operator= ( ManagedBytes && other )

noexcept

Move assignment operator.

Parameters

other the MangedBytes to be moved

Returns: this object

Definition at line 75 of file ManagedBytes.cpp.

◆ read()

bool ManagedBytes::read ( ConnectionReader & reader )

overridevirtual

Read this object from a network connection.

Override this for your particular class.

Parameters

reader an interface to the network connection for reading

Returns: true iff the object is successfully read

Implements yarp::os::Portable.

Definition at line 207 of file ManagedBytes.cpp.

◆ resetUsed()

size_t ManagedBytes::resetUsed ( )

Definition at line 199 of file ManagedBytes.cpp.

◆ setUsed()

size_t ManagedBytes::setUsed ( size_t used )

explicitly declare how many of the bytes are in use.

Parameters

used	byte count

Returns: a confirmation of the number of bytes declared to be in use.

Definition at line 192 of file ManagedBytes.cpp.

◆ used()

size_t ManagedBytes::used ( ) const

Returns: length of used portion of data block - by default, this is the same as length(), unless setUsed() is called

Definition at line 149 of file ManagedBytes.cpp.

◆ usedBytes()

Bytes ManagedBytes::usedBytes ( )

Returns: description of used portion of data block associated with this object

Definition at line 187 of file ManagedBytes.cpp.

◆ write()

bool ManagedBytes::write ( ConnectionWriter & writer ) const

overridevirtual

Write this object to a network connection.

Override this for your particular class. Be aware that depending on the nature of the connections a port has, and what protocol they use, and how efficient the YARP implementation is, this method may be called once, twice, or many times, as the result of a single call to Port::write

Parameters

writer an interface to the network connection for writing

Returns: true iff the object is successfully written

Implements yarp::os::Portable.
