Represents a single instance of the opaque data preceded by length.
LengthFieldType
Size of the length field in the tuple.
This class encapsulates a collection of data tuples and could be used by multiple options.
void setTuple(const size_t at, const OpaqueDataTuple &tuple)
Replaces tuple at the specified index with a new tuple.
virtual std::string toText(int indent=0) const
Returns text representation of the option.
const TuplesCollection & getTuples() const
Returns collection of opaque data tuples carried in the option.
size_t getTuplesNum() const
Returns the number of opaque data tuples added to the option.
virtual void unpack(OptionBufferConstIter begin, OptionBufferConstIter end)
Parses buffer holding an option.
void addTuple(const OpaqueDataTuple &tuple)
Adds a new opaque data tuple to the option.
virtual uint16_t len() const
Returns the full length of the option, including option header.
std::vector< OpaqueDataTuple > TuplesCollection
Collection of opaque data tuples carried by the option.
OptionPtr clone() const
Copies this option and returns a pointer to the copy.
virtual void pack(isc::util::OutputBuffer &buf, bool check=true) const
Renders option into the buffer in the wire format.
OpaqueDataTuple getTuple(const size_t at) const
Returns opaque data tuple at the specified position.
bool hasTuple(const std::string &tuple_str) const
Checks if the object holds the opaque data tuple with the specified string.

Definition: option.h:83
void check() const
A protected method used for option correctness.
Definition: option.cc:90
The OutputBuffer class is a buffer abstraction for manipulating mutable data.
Definition: buffer.h:347
boost::shared_ptr< OptionOpaqueDataTuples > OptionOpaqueDataTuplesPtr
Defines a pointer to the OptionOpaqueDataTuples.
OptionBuffer::const_iterator OptionBufferConstIter
const_iterator for walking over OptionBuffer
Definition: option.h:30
boost::shared_ptr< Option > OptionPtr
Definition: option.h:37
Defines the logger used by the top-level component of kea-lfc.
