# Class: com.pnfsoftware.jeb.core.units.code.asm.decompiler.ir.MemoryAccessInfo

Memory access information object.

## Constructor: MemoryAccessInfo

Description: Create a mutable \(customizable\) MAI object initially set to access everything \(stack R/W, globals R/W\). 

 Customize accesses with [#setGlobalsAccessRanges(IdRanges, IdRanges)](#setGlobalsAccessRanges(IdRanges, IdRanges)), [#setStackAccessRanges(IdRanges, IdRanges)](#setStackAccessRanges(IdRanges, IdRanges)), [#setStackSpoiledRanges(IdRanges)](#setStackSpoiledRanges(IdRanges)).

## Constructor: MemoryAccessInfo
- parameter: `accessEverything`, type: `boolean`

Description: Create a mutable \(customizable\) MAI object. 

 Customize accesses with [#setGlobalsAccessRanges(IdRanges, IdRanges)](#setGlobalsAccessRanges(IdRanges, IdRanges)), [#setStackAccessRanges(IdRanges, IdRanges)](#setStackAccessRanges(IdRanges, IdRanges)), [#setStackSpoiledRanges(IdRanges)](#setStackSpoiledRanges(IdRanges)).
parameter: accessEverything: false to initialize to access nothing \(in stack, in mem\); trues to            initialize to access everything \(safer\)

## Constructor: MemoryAccessInfo
- parameter: `readStack`, type: `boolean`
- parameter: `writeStack`, type: `boolean`
- parameter: `readGlobals`, type: `boolean`
- parameter: `writeGlobals`, type: `boolean`

Description: 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()](#MemoryAccessInfo()).
