Public Methods
public abstract void addListener (IMemoryModelListener listener)
Register a listener that will receive updates when this model is updated.
public abstract int getBitsize ()
Retrieve the bitsize
public abstract ICommentManager getCommentManager ()
Retrieve the comment manager associated with this model.
public abstract SortedMap<Long, INativeContinuousItem> getContinuousItemsInRange (long addressBegin, long addressEnd)
Get a contiguous list of items, without gaps. The last item, if present, may have an
end-address past `addressEnd`. Gaps are filled using getGapFactory().
Returns
- a list of items, with gap items to fill in possible gaps
public abstract ISegmentFactory<Long, INativeContinuousItem> getGapFactory ()
Retrieve a "gap items" factory. The factory is used to produce temporary items to fill in
gaps, when using methods like getContinuousItemsInRange(long, long).
Returns
- a factory (mandatory)
public abstract INativeContinuousItem getItemAt (long address)
Retrieve the item starting at the given address.
Returns
- the item or null
public abstract INativeContinuousItem getItemOver (long address)
Retrieve the item spanning over the given address.
Returns
- the item or null
public abstract INativeContinuousItem getItemOverOrGap (long address, long lowerBound, long upperBound)
Retrieve the item spanning over the given address, or if no item exists, return a temporary item that fills the gap, partially or fully. In the latter case, the gap item is not attached to the memory model.
Parameters
| address | the address to be queried; the address must be in the bounds range defined below |
|---|---|
| lowerBound | the lower bound for the gap, if no item was found |
| upperBound | the higher bound for the gap, used if no item was found; must be >= that the lower bound |
Returns
- an item or a gap item, or null if the addresses are invalid
public abstract SortedMap<Long, INativeContinuousItem> getItemsInRange (long addressBegin, boolean includePartialFirstItem, long addressEnd, boolean includePartialLastItem)
Get a map of items in the given range.
Parameters
| includePartialFirstItem | include the first item if it spans over (not starts on) the start address |
|---|---|
| includePartialLastItem | include the last item if it spans over (not ends on) the last address |
public abstract ILabelManager getLabelManager ()
Retrieve the label manager associated with this model.
public abstract IUnitLock getLock ()
Retrieve the model lock, used to request a full-access model lock or a partial, read-only, transactional lock. All plugin code accessing the native units and units relying on native units should use those locks to perform operations safely in a concurrent environment.
public abstract INativeContinuousItem getNextItem (long address)
Retrieve the closest item whose address is strictly greater than the provided address.
Returns
- the next item or null
public abstract INativeContinuousItem getNextItem (INativeContinuousItem item)
Retrieve the closest item after the given one..
Returns
- the next item or null
public abstract INativeContinuousItem getPreviousItem (INativeContinuousItem item)
Retrieve the closest before the given one..
Returns
- the next item or null
public abstract INativeContinuousItem getPreviousItem (long address)
Retrieve the closest item whose address is strictly less than the provided address.
Returns
- the previous item or null
public abstract SortedMap<Long, INativeContinuousItem> getView (Long fromAddress, Long toAddress)
Get a copy view of the current model.
Parameters
| fromAddress | optional start address |
|---|---|
| toAddress | optional end address |
Returns
- an unmodifiable view of the model containing the native items
public abstract SortedMap<Long, INativeContinuousItem> getView ()
Get a full view of the current model. Same as getView(null,
null).
Returns
- an unmodifiable view of the model containing the native items
public abstract boolean isEmpty ()
Determine if the model is empty.
public abstract boolean isEmptyRange (long address, int size)
Determine if a provided range is free (ie, contains no item or overlapping item).
public abstract void notifyListenersOfModelChange (MemoryModelEventType eventType, Object eventDetails)
Issue a notification of model change to all listeners.
public abstract int size ()
Provide the number of elements in the model.
