Detailed Description

Hold a memory block and symbol informations.

Memory class to hold memory content and symbol informations to map symbols to addresses and vice versa.

Constructor & Destructor Documentation

Memory::Memory ( int size )

Creates the memory block

Parameters:

size

Member Function Documentation

void Memory::AddSymbol ( std::pair< unsigned int, std::string > p ) [inline]

Add the (address, symbol) pair

Parameters:

p

a std::pair with address and symbol string

Definition at line 82 of file memory.h.

References sym.

Here is the caller graph for this function:

unsigned int Memory::GetAddressAtSymbol ( const std::string & s )

Returns the address for a symbol

If the given string is a hex string, the hex value will be converted and returned. If the symbol isn't found, program aborts.

Parameters:

s

the symbol string or hex string

Returns:: address for symbol or value of hex string

Todo:: if the symbol isn't found, it aborts with a message. Maybe it should raise a exeption to handle this on the caller side?

Here is the caller graph for this function:

string Memory::GetSymbolAtAddress ( unsigned int add )

Return string with symbols found at address

Seeks for symbols, which are registered for the given address. If the address isn't equal to a symbol address, but before the next one, then a offset to symbol address will be added. Returns a empty string, if nothing is found. (in case of no given symbols!)

Parameters:

add

the given address
