Constructor Details

StateMemBuffer

public StateMemBuffer(Address address,
 BytesPcodeExecutorStateSpace source,
 PcodeExecutorStatePiece.Reason reason)

Construct a buffer bound to the given space, at the given address

Parameters:

address - the address

source - the space (null will cause readUninit and re-fetch on read attempts)

reason - the reason this buffer reads from the state, as in PcodeExecutorStatePiece.getVar(Varnode, Reason)

Method Details

getAddress

public Address getAddress()

Description copied from interface: MemBuffer

Get the Address which corresponds to the offset 0.

Specified by:

getAddress in interface MemBuffer

Returns:

the current address of offset 0.

getMemory

public Memory getMemory()

Description copied from interface: MemBuffer

Get the Memory object actually used by the MemBuffer.

Specified by:

getMemory in interface MemBuffer

Returns:

the Memory used by this MemBuffer or null if not available.

isBigEndian

public boolean isBigEndian()

Description copied from interface: MemBuffer

Returns true if the underlying bytes are in big-endian order, false if they are little endian.

Specified by:

isBigEndian in interface MemBuffer

Returns:

true if the underlying bytes are in big-endian order, false if they are little endian.

getBytes

public int getBytes(ByteBuffer buffer,
 int addressOffset)

Specified by:

getBytes in interface MemBufferMixin
