  • action (function) - (Optional) Action callback function.

    See Debug.define_page_breakpoint for more details.

remove(self, address, size)

source code 

Removes a buffer from the watch object.

Parameters:
  • address (int) - Memory address of buffer to stop watching.
  • size (int) - Size in bytes of buffer to stop watching.

exists(self, address, size)

source code 
Parameters:
  • address (int) - Memory address of buffer being watched.
  • size (int) - Size in bytes of buffer being watched.
Returns: bool
True if the buffer is being watched, False otherwise.

span(self)

source code 
Returns: tuple( int, int )
Base address and size in pages required to watch all the buffers.

count(self)

source code 
Returns: int
Number of buffers being watched.

__call__(self, event)
(Call operator)

source code 

Breakpoint condition callback.

This method will also call the action callbacks for each buffer being watched.

Parameters:
Returns: bool
