This data structure is to contain the packed form of an encodable knowledge.

It servers two purposes:

Constructor & Destructor Documentation

AlpsEncoded::AlpsEncoded ( const AlpsEncoded )
private

Disable copy constructor and assignment operator.

AlpsEncoded::AlpsEncoded ( )
inline

The default constructor creates a buffer of size 16 Kbytes with no message in it.

Definition at line 65 of file AlpsEncoded.h.

AlpsEncoded::AlpsEncoded ( int  t)
inline

Useful constructor.

Definition at line 75 of file AlpsEncoded.h.

AlpsEncoded::AlpsEncoded ( int  t,
int  s,
char *&  r 
)
inline

Useful constructor.

Take over ownership of r.

Definition at line 85 of file AlpsEncoded.h.

AlpsEncoded::~AlpsEncoded ( )
inline

Destructor.

Definition at line 95 of file AlpsEncoded.h.

void AlpsEncoded::setRepresentation ( char *&  buf)
inline

Definition at line 120 of file AlpsEncoded.h.

void AlpsEncoded::make_fit ( const int  addSize)
inline

Reallocate the size of encoded if necessary so that at least addsize_ number of additional bytes will fit into the encoded.

Definition at line 130 of file AlpsEncoded.h.

void AlpsEncoded::clear ( )
inline

Completely clear the encoded.

Delete and zero out type_, size_, pos_.

Definition at line 146 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::writeRep ( const T &  value)
inline

Write a single object of type T in repsentation_ .

Copies sizeof(T) bytes from the address of the object.

Definition at line 163 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::readRep ( T &  value)
inline

Read a single object of type T from repsentation_ .

Copies sizeof(T) bytes to the address of the object.

Definition at line 173 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::writeRep ( const T *const  values,
const int  length 
)
inline

Write a C style array of objects of type T in repsentation_.

First write the length, then write the content of the array

Definition at line 189 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::readRep ( T *&  values,
int &  length,
bool  needAllocateMemory = true 
)
inline

Read an array of objects of type T from repsentation_, where T must be a built-in type (ar at least something that can be copied with memcpy).

If the third argument is true then memory is allocated for the array and the array pointer and the length of the array are returned in the arguments.

If the third argument is false then the arriving array's length is compared to length and an exception is thrown if they are not the same. Also, the array passed as the first argument will be filled with the arriving array.

Definition at line 216 of file AlpsEncoded.h.

AlpsEncoded& AlpsEncoded::writeRep ( std::string &  value)
inline

Read a std::string in repsentation_ .

Definition at line 281 of file AlpsEncoded.h.

AlpsEncoded& AlpsEncoded::readRep ( std::string &  value)
inline

Read a std::string from repsentation_ .

Definition at line 295 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::writeRep ( const std::vector< T > &  vec)
inline

Write a std::vector into repsentation_ .

Definition at line 304 of file AlpsEncoded.h.

template<class T >
AlpsEncoded& AlpsEncoded::readRep ( std::vector< T > &  vec)
inline

Read a std::vector from repsentation_ .

Definition at line 318 of file AlpsEncoded.h.

Member Data Documentation

size_t AlpsEncoded::pos_
private

The next read/write position in the representation.

Definition at line 38 of file AlpsEncoded.h.

size_t AlpsEncoded::maxSize_
private

The amount of memory allocated for the representation.

Definition at line 41 of file AlpsEncoded.h.

int AlpsEncoded::type_
private

Represent the type of the object.

We might use RTTI to point this into the static data of the executable :-) Can only be initialized during constructing. User take care of memory.

Definition at line 49 of file AlpsEncoded.h.

int AlpsEncoded::size_
private

The size of the packed representation.

Definition at line 52 of file AlpsEncoded.h.

char* AlpsEncoded::representation_
private

The encoded/compressed representation of the object.

Definition at line 56 of file AlpsEncoded.h.
