reven2.search_in_memory.Match(object) class documentation

Part of reven2.search_in_memory (View In Hierarchy)

Represents a slice of memory that matches a specific pattern during some portion of the trace.

Matches are typically produced by Search.matches().

Method __init__ Undocumented
Method id Property: The unique id of the pattern in the Search instance that produced it.
Method physical_start_address Property: The reven2.address.PhysicalAddress of the first byte of the slice that matches the pattern.
Method physical_end_address Property: The reven2.address.PhysicalAddress of the first byte after the slice that matches the pattern.
Method virtual_start_address Property: The reven2.address.LinearAddress of the first byte of the slice that matches the pattern, or None, if the match was created by a physical write.
Method virtual_end_address Property: The reven2.address.LinearAddress of the first byte after the slice that matches the pattern, or None, if the match was created by a physical write.
Method known_mapped_context Property: A reven2.trace.Context where it's known that the virtual_start_address is mapped, or None, if unknown.
Method size_byte Property: The size of the match, in byte.
Method first_context Property: The first reven2.trace.Context where this slice matches the pattern.
Method last_context Property: The last reven2.trace.Context where this slice matches the pattern.
Method creation_transition Property: The reven2.trace.Transition that make the slice match the pattern, or None if the slice was alreadying matching the pattern in the from_context of the search.
Method destruction_transition Property: The reven2.trace.Transition that make the slice stop matching the pattern, or None if the slice matches the pattern until the to_context of the search.
Method accesses A generator of the reven2.memhist.MemoryAccesses that read from the slice while it was matching with the pattern.
Method pattern The pattern that the slice matches with.

Note

For Matches that are still alive in searches that are not completed, this will be updated as the search progresses
