Class ELFStandardRelocOperations

java.lang.Object

com.pnfsoftware.jeb.core.units.codeobject.ELFStandardRelocOperations

public class ELFStandardRelocOperations
extends Object

Default implementation for ELF relocation operations, for a given relocation. It can be overridden to add operations or customize existing common operations (A, S, P, B).

This class contains operations shared among architectures.

Constructor Details

ELFStandardRelocOperations

public ELFStandardRelocOperations(IELFRelocationApplicator.RelocatedFile relocEnvironment,
 IELFRelocationApplicator.RelocInstance relocInstance)

Create standard relocation operations.

Parameters:

relocEnvironment - relocation file information

Method Details

A

public long A()
       throws MemoryException

Represents the addend used to compute the value of the relocatable field.

Returns:

addend value

Throws:

MemoryException - if the implicit addend cannot be read

S

public long S()

Represents the value of the symbol whose index resides in the relocation entry.

Returns:

symbol value

P

public long P()

Represents the place, as section offset or address, of the storage unit being relocated.

Returns:

relocation place

B

public long B()

Represents the base address at which a shared object was loaded.

Returns:

actual image base
