Fields
Public Constructors
public MemoryAccessInfo ()
Create a mutable (customizable) MAI object initially set to access everything (stack R/W,
globals R/W). Customize accesses with
#setCustomGlobalsAccessRanges(IdRanges, IdRanges),
#setCustomStackAccessRanges(IdRanges, IdRanges),
setStackSpoiledRanges(IdRanges).
public MemoryAccessInfo (boolean readStack, boolean writeStack, boolean readGlobals, boolean writeGlobals)
Create an immutable MAI object with no-granularity settings: all/no stack read, all/no stack
written, all/no globals read, all/no globals written. In order to specify granular access
settings (list of variable IDs), use MemoryAccessInfo().
