ghidra.program.model.lang.protorules.ConvertToPointer

public class ConvertToPointer
extends AssignAction

Action converting the parameter's data-type to a pointer, and assigning storage for the pointer. This assumes the data-type is stored elsewhere and only the pointer is passed as a parameter.

Method Summary

Modifier and Type	Method	Description
int	assignAddress(DataType dt, PrototypePieces proto, int pos, DataTypeManager dtManager, int[] status, ParameterPieces res)	Assign an address and other meta-data for a specific parameter or for return storage in context The Address is assigned based on the data-type of the parameter, available register resources, and other details of the function prototype.

Method Details

clone

public AssignAction clone(ParamListStandard newResource)
                   throws InvalidInputException

Description copied from class: AssignAction

Make a copy of this action

Specified by:

clone in class AssignAction

Parameters:

newResource - is the new resource object that will own the clone

Returns:

the newly allocated copy

Throws:

InvalidInputException - if required configuration is not present in new resource object

isEquivalent

public boolean isEquivalent(AssignAction op)

Description copied from class: AssignAction

Test if the given action is configured and performs identically to this

Specified by:

isEquivalent in class AssignAction

Parameters:

op - is the given action

Returns:

true if the two actions are equivalent

assignAddress

public int assignAddress(DataType dt,
 PrototypePieces proto,
 int pos,
 DataTypeManager dtManager,
 int[] status,
 ParameterPieces res)

Description copied from class: AssignAction

Assign an address and other meta-data for a specific parameter or for return storage in context The Address is assigned based on the data-type of the parameter, available register resources, and other details of the function prototype. Consumed resources are marked. This method returns a response code: - SUCCESS - indicating the Address was successfully assigned - FAIL - if the Address could not be assigned - HIDDENRET_PTRPARAM - if an additional hidden return parameter is required

Specified by:

assignAddress in class AssignAction

Parameters:

dt - is the data-type of the parameter or return value

proto - is the high-level description of the function prototype

pos - is the position of the parameter (pos>=0) or return storage (pos=-1)

dtManager - is a data-type manager for (possibly) transforming the data-type

status - is the resource consumption array

res - will hold the resulting description of the parameter

Returns:

the response code

encode

public void encode(Encoder encoder)
            throws IOException

Description copied from class: AssignAction

Save this action and its configuration to a stream

Specified by:

encode in class AssignAction

Parameters:

encoder - is the stream encoder

Throws:

IOException - for problems writing to the stream

restoreXml

public void restoreXml(XmlPullParser parser)
                throws XmlParseException

Description copied from class: AssignAction

Configure any details of how this action should behave from the stream

Specified by:

restoreXml in class AssignAction

Parameters:

parser - is the given stream decoder

Throws:

XmlParseException - is there are problems decoding the stream
