maat::MemConcreteBuffer class

Reference

This class represents a concrete memory area. It's basically a wrapper around a buffer that enables to read/write constants of different sizes

For performance reasons, no checks are performed on the read/write operations to make sure that they don't overflow the bounds of the buffer. It is up to the caller to verify that the arguments passed are consistent.

❱ Base classes

class Serializable: Virtual interface that serializable classes must implement.

❱ Public functions

void extend_after(offset_t nb_bytes)
void extend_before(offset_t nb_bytes)
void write(offset_t off, int64_t val, int nb_bytes): Write the value 'val' on 'nb_bytes' starting from offset 'off'.
void write(offset_t off, const Number& val, int nb_bytes): Write the value 'val' on 'nb_bytes' starting from offset 'off'.
auto is_identical_until(offset_t start, offset_t end, uint8_t val) -> offset_t: Returns the closest offset from 'start' and before 'end' (included) which holds a value different from 'val'.
auto raw_mem_at(offset_t off) -> uint8_t*: Returns a raw pointer to the concrete memory buffer at offset 'off'.
auto class_uid() const -> uid_t virtual: Return the class uid (see ClassId enum)
void dump(serial::Serializer&) const virtual: Dump the object contents in a serializer stream.
void load(serial::Deserializer&) virtual: Restore an object from a deserializer stream.

❱ Function documentation

void maat::MemConcreteBuffer::extend_after(offset_t nb_bytes)

Extend the buffer to make it represent 'nb_bytes' more bytes of memory. The new bytes are inserted at the end of the buffer

void maat::MemConcreteBuffer::extend_before(offset_t nb_bytes)

Extend the buffer to make it represent 'nb_bytes' more bytes of memory. The new bytes are inserted at the beginning of the buffer
