The memory state m must have a BaseSemantics::MemoryCellState dynamic type.

virtual |
Clear memory.
Removes all memory cells from this memory state.
Implements Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryState.
Reimplemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.
|
pure virtual |
Writers for an address.
Returns the set of all writers that wrote to the specified address or any address that might alias the specified address. Memory states that don't normally compute aliases (e.g., MemoryCellMap) return only the writers for the specified address, not any aliases, and in this case getWritersUnion and getWritersIntersection return the same set.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.

Find all matching cells.
Returns a vector of cells for which the predicate returns true.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.

|
pure virtual |
Find leading matching cells.
Returns the vector of cells obtained by invoking the predicate on each cell and returning those leading cells for which the predicate is true. The first cell for which the predicate is false terminates the traversal and does not appear in the return value.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.
|
pure virtual |
Remove all matching cells.
Traverses the memory cells and removes those for which the predicate returns true.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.

pure virtual |
Remove leading matching cells.
Traverses the memory cells and removes those for which the predicate returns true. The traversal is terminated the first time the predicate returns false.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.
|
pure virtual |
Traverse and modify cells.
Traverse cells and optionally modify them.
Implemented in Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellList, and Rose::BinaryAnalysis::InstructionSemantics2::BaseSemantics::MemoryCellMap.
