Member Function Documentation

void CMPISGBufferLeaf::append ( int i ) [virtual]

Append an integer to the buffer.

Warning:: No check for overflow

Implements AMPISGBufferLeaf.

References AMPIBuffer::m_comm.

Referenced by TSubLattice< T >::checkNeighbors().

Here is the caller graph for this function:

void CMPISGBufferLeaf::append ( double d ) [virtual]

Append a double to the buffer.

Warning:: No check for overflow

Implements AMPISGBufferLeaf.

References AMPIBuffer::m_comm.

void CMPISGBufferLeaf::append ( const char * str ) [virtual]

Append a string to the buffer. The string appended is a normal (zero-terminated) C-string, but is internally handeled by packing the length frist and then the string.

Warning:: No check for overflow

Implements AMPIBuffer.

References AMPIBuffer::m_comm.

double CMPISGBufferLeaf::pop_double ( ) [virtual]

Pops a double from the buffer.

Warning:: No check for underflow

Returns:: the double.

See also:: CMPIBuffer::pop_int()

Implements AMPISGBufferLeaf.

References AMPIBuffer::m_comm.

int CMPISGBufferLeaf::pop_int ( ) [virtual]

Pops an integer from the buffer, i.e. it pops the last sizeof(MPI_INT) bytes of the buffer, interpreting them as an int.

Warning:: No check for underflow

Returns:: the int.

Implements AMPISGBufferLeaf.

References AMPIBuffer::m_comm.

std::string CMPISGBufferLeaf::pop_string ( ) [virtual]

Pops a string from the buffer. The first for bytes are interpreted as int, giving the length of the string (without terminating '\0'), the rest as the characters.
