Detailed Description
The srecord::memory_walker_compare class is used to represent a memory walker which compares memory data with another memory instance.
Note that this is strictly an improper subset comparison. I.e. that all bytes passed to the observe method exists in the other memory instance.
For a complete equality test, you need to use this comparison both ways round.
Member Typedef Documentation
◆ pointer
| typedef std::shared_ptr<memory_walker_compare> srecord::memory_walker_compare::pointer |
Constructor & Destructor Documentation
◆ ~memory_walker_compare()
|
virtual |
The destructor.
Member Function Documentation
◆ create()
|
static |
The create class method is used to create new dynamically allocated instances of this class.
- Parameters
-
other The other memory instance to be checked against this one. check_wrong Whether or not to check that the data agrees as well as the address ranges.
◆ observe()
|
virtual |
The observe method is used by the memory walker to provide data.
Derived classes are required to impliment this method, and do something with the data.
- Parameters
-
address The base address of this chunk of memory. data The base address of this chunk of memory in memory. data_size The size, in bytes, of this chunk of memory.
Implements srecord::memory_walker.
◆ print()
| void srecord::memory_walker_compare::print | ( | const char * | caption | ) | const |
The print method is used to print the results of the comparison on the standard output.
- Parameters
-
caption The text to place at the start of the listing.
◆ same()
| bool srecord::memory_walker_compare::same | ( | ) | const |
The same method is used to discover whether the result of the comparison indicate that the two memory instances are the same.
