ghidra.program.model.pcode.HighCodeSymbol

public class HighCodeSymbol
extends HighSymbol

A global symbol as part of the decompiler's model of a function. This symbol can be backed by a formal CodeSymbol, obtained using getCodeSymbol(). This symbol can be backed by a formal Data object, obtained using getData(). If there is a backing CodeSymbol, this takes its name, otherwise the name is dynamically generated using SymbolUtilities. The data-type attached to this does not necessarily match the backing CodeSymbol or Data object.

Constructor Details

HighCodeSymbol

public HighCodeSymbol(CodeSymbol sym,
 DataType dataType,
 int sz,
 HighFunction func)

Construct with a backing CodeSymbol. An attempt is made to also find a backing Data object.

Parameters:

sym - is the backing CodeSymbol

dataType - is the (possibly distinct) data-type associated with the new HighSymbol

sz - is the storage size, in bytes, of the symbol

func - is the decompiler function model owning the new HighSymbol

HighCodeSymbol

public HighCodeSymbol(long id,
 Address addr,
 DataType dataType,
 int sz,
 HighFunction func)

Construct with just a (global) storage address and size. There will be no backing CodeSymbol. An attempt is made to find a backing Data object.

Parameters:

id - is the id to associate with the new HighSymbol

addr - is the starting Address of the symbol storage

dataType - is the data-type associated with the new symbol

sz - is the size of the symbol storage in bytes

func - is the decompiler function model owning the new symbol

HighCodeSymbol

public HighCodeSymbol(long id,
 String nm,
 Data data,
 PcodeDataTypeManager dtmanage)

Constructor for HighSymbol which is unattached to a HighFunction

Parameters:

id - is the unique id to assign

nm - is the name of the symbol

data - is an underlying Data object defining the storage and data-type

dtmanage - is the data-type manager for XML reference

Method Details

isGlobal

public boolean isGlobal()

Description copied from class: HighSymbol

Is this symbol in the global scope or some other global namespace

Overrides:

isGlobal in class HighSymbol

Returns:

true if this is global

getCodeSymbol

public CodeSymbol getCodeSymbol()

Get the CodeSymbol backing this, if it exists

Returns:

the CodeSymbol or null

getData

public Data getData()

Get the Data object backing this, if it exists

Returns:

the Data object or null

decode

public void decode(Decoder decoder)
            throws DecoderException

Description copied from class: HighSymbol

Decode this symbol object and its associated mappings from the stream.

Overrides:

decode in class HighSymbol

Parameters:

decoder - is the stream decoder

Throws:

DecoderException - for invalid encodings
