abstract void	allocate(long address, int size, int protection) Allocate the entire memory range or nothing.
abstract int	check(long address, int size, int protection) Check if a memory range has at least the given set of protection flags.
abstract int	getPageProtection(long address) Set the protection flags for a page.
abstract int	getPageSize() Get the size of a page in bytes.
abstract int	getSpaceBits() Get the size of this memory space in bits.
abstract boolean	isValidAddress(long address) Determine if an address is valid for this memory space.
abstract int	read(long address, int size, byte[] dst, int dstOffset) Read a range of bytes.
abstract byte	readByte(long address) Read a byte.@return
abstract int	readLEInt(long address) Read a little-endian 32-bit integer.
abstract long	readLELong(long address) Read a little-endian 64-bit integer.
abstract short	readLEShort(long address) Read a little-endian 16-bit integer.
abstract long	roundToPage(long address) Round an address to the page this address currently resides in, that is the highest page so that boundary ≤ address.
abstract long	roundToSize(long address) Round an address to the lowest page boundary so that address ≤ boundary.
abstract void	setPageProtection(long address, int protection) Get the protection flags for a page.
abstract int	write(long address, int size, byte[] src, int srcOffset) Write a range of bytes.
abstract void	writeByte(long address, byte v) Write a byte.
abstract void	writeLEInt(long address, int v) Write a little-endian 32-bit integer.
abstract void	writeLELong(long address, long v) Write a little-endian 64-bit integer.
abstract void	writeLEShort(long address, short v) Write a little-endian 16-bit integer.

Public Methods

public abstract long findBytes (long address, long maxsize, byte[] pattern)

Search a memory area for a specific byte sequence.

Parameters

address	base address - in the case of a 64-bit address above 2^63 bytes, the address is theoretically negative
maxsize	size of the area to be searched, at most 2^63 bytes - consequently, a full 64-bit memory space search must be done in two operations
pattern	a sequence of bytes to look for - at least 1 byte

Returns

an offset, relative to the input base address; -1 indicates the pattern was not found
