Member Function Documentation

addCodeBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::addCodeBlocks ( ByteInterval *  BI, ByteInterval::code_block_range  Blocks  )

pure virtual

Notify the parent when new CodeBlocks are added to the interval.

Called after the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval to which the CodeBlocks were added.
Blocks	a range containing the new CodeBlocks.

Returns

indication of whether the observer accepts the change.

addDataBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::addDataBlocks ( ByteInterval *  BI, ByteInterval::data_block_range  Blocks  )

pure virtual

Notify the parent when new DataBlocks are added to the interval.

Called after the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval to which the DataBlocks were added.
Blocks	a range containing the new DataBlocks.

Returns

indication of whether the observer accepts the change.

changeExtent()

virtual ChangeStatus gtirb::ByteIntervalObserver::changeExtent ( ByteInterval *  BI, std::function< void(ByteInterval *)>  Callback  )

pure virtual

Notify the parent when the range of addresses in the interval changes.

Called before the ByteInterval's extent changes. This method should invoke the callback with BI to update its extent.

Parameters

BI	the ByteInterval that changed.
Callback	callable to update the ByteInterval's extent.

Returns

indication of whether the observer accepts the change.

moveCodeBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::moveCodeBlocks ( ByteInterval *  BI, ByteInterval::code_block_range  Blocks  )

pure virtual

Notify the parent when the addresses of existing CodeBlocks change.

Called after the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval containing the CodeBlocks.
Blocks	a range containing the CodeBlocks that moved.

Returns

indication of whether the observer accepts the change.

moveDataBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::moveDataBlocks ( ByteInterval *  BI, ByteInterval::data_block_range  Blocks  )

pure virtual

Notify the parent when the addresses of existing CodeBlocks change.

Called after the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval containing the DataBlocks.
Blocks	a range containing the DataBlocks that moved.

Returns

indication of whether the observer accepts the change.

removeCodeBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::removeCodeBlocks ( ByteInterval *  BI, ByteInterval::code_block_range  Blocks  )

pure virtual

Notify the parent when CodeBlocks are removed from the interval.

Called before the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval from which the CodeBlocks will be removed.
Blocks	a range containing the CodeBlocks to remove.

Returns

indication of whether the observer accepts the change.

removeDataBlocks()

virtual ChangeStatus gtirb::ByteIntervalObserver::removeDataBlocks ( ByteInterval *  BI, ByteInterval::data_block_range  Blocks  )

pure virtual

Notify the parent when DataBlocks are removed from the interval.

Called before the ByteInterval updates its internal state.

Parameters

BI	the ByteInterval from which the DataBlocks will be removed.
Blocks	a range containing the DataBlocks to remove.

Returns

indication of whether the observer accepts the change.
