Class PackedEncodeOverlay

java.lang.Object

ghidra.program.model.pcode.PackedEncode

ghidra.program.model.pcode.PatchPackedEncode

ghidra.program.model.pcode.PackedEncodeOverlay

All Implemented Interfaces:

CachedEncoder, Encoder, PatchEncoder

public class PackedEncodeOverlay
extends PatchPackedEncode

Alter address space encoding for a specific overlay space. Any space that matches the overlay space is encoded as the overlayed space. This causes addresses in the overlay space to be converted into the underlying space.

Modifier and Type	Method	Description
void	setOverlay(OverlayAddressSpace spc)
void	writeSpace(AttributeId attribId, AddressSpace spc)	Write an address space reference into the encoding The address space is associated with the given AttributeId annotation and the current open element.

PackedEncodeOverlay

public PackedEncodeOverlay(OverlayAddressSpace spc)
                    throws AddressFormatException

Throws:

AddressFormatException

Method Details

setOverlay

public void setOverlay(OverlayAddressSpace spc)
                throws AddressFormatException

Throws:

AddressFormatException

writeSpace

public void writeSpace(AttributeId attribId,
 AddressSpace spc)
                throws IOException

Description copied from interface: Encoder

Write an address space reference into the encoding The address space is associated with the given AttributeId annotation and the current open element.

Specified by:

writeSpace in interface Encoder

Overrides:

writeSpace in class PackedEncode

Parameters:

attribId - is the given AttributeId annotation

spc - is the address space to encode

Throws:

IOException - for errors in the underlying stream

writeSpaceId

public void writeSpaceId(AttributeId attribId,
 long spaceId)
                  throws IOException

Description copied from interface: PatchEncoder

Write a given raw spaceid (as returned by AddressSpace.getSpaceID()) as an attribute. The effect is the same as if writeSpace() was called with the AddressSpace matching the spaceid, i.e. the decoder will read this as just space attribute.

Specified by:

writeSpaceId in interface PatchEncoder

Overrides:

writeSpaceId in class PatchPackedEncode

Parameters:

attribId - is the attribute

spaceId - is the given spaceid

Throws:

IOException - for problems writing to the stream
