Constructor Detail

MachOSymtab

public MachOSymtab(String name,
                   MachOObjectFile objectFile,
                   MachOObjectFile.Segment64Command containingSegment,
                   MachOStrtab strtab)

Method Detail

getSortedEntries

public List<com.oracle.objectfile.macho.MachOSymtab.Entry> getSortedEntries()

getDependencies

public Iterable<BuildDependency> getDependencies(Map<ObjectFile.Element,LayoutDecisionMap> decisions)

Description copied from interface: ElementImpl

Implementing this method allows to declare dependencies to other Sections (i.e. information about other sections needed to construct this section). The information will be used to construct the buildOrder in ObjectFile.writeInternal(). A good example can be found at: ELFObjectFile.ProgramHeaderTable.getDependencies

Specified by:

getDependencies in interface ElementImpl

getOrDecideOffset

public int getOrDecideOffset(Map<ObjectFile.Element,LayoutDecisionMap> alreadyDecided,
                             int offsetHint)

Description copied from interface: ElementImpl

Implement this method to provide the offset this section should be placed at.

Specified by:

getOrDecideOffset in interface ElementImpl

getOrDecideSize

public int getOrDecideSize(Map<ObjectFile.Element,LayoutDecisionMap> alreadyDecided,
                           int sizeHint)

Description copied from interface: ElementImpl

Implement this method to provide the size of this section.

Specified by:

getOrDecideSize in interface ElementImpl

getOrDecideContent

public byte[] getOrDecideContent(Map<ObjectFile.Element,LayoutDecisionMap> alreadyDecided,
                                 byte[] contentHint)

Description copied from interface: ElementImpl

Implement this method to deliver the content of the section.

Specified by:

getOrDecideContent in interface ElementImpl

getOrDecideVaddr

public int getOrDecideVaddr(Map<ObjectFile.Element,LayoutDecisionMap> alreadyDecided,
                            int vaddrHint)

Description copied from interface: ElementImpl

Implement this method to provide the virtual address of this section. For loadable sections, this is where the section is expected to be mapped to at runtime (see ElementImpl.isLoadable()).

Specified by:

getOrDecideVaddr in interface ElementImpl

getDecisions

public LayoutDecisionMap getDecisions(LayoutDecisionMap copyingIn)

Specified by:

getDecisions in interface ElementImpl

newDefinedEntry

public ObjectFile.Symbol newDefinedEntry(String name,
                                         ObjectFile.Section referencedSection,
                                         long referencedOffset,
                                         long size,
                                         boolean isGlobal,
                                         boolean isCode)

Specified by:

newDefinedEntry in interface SymbolTable

newUndefinedEntry

public ObjectFile.Symbol newUndefinedEntry(String name,
                                           boolean isCode)

Specified by:

newUndefinedEntry in interface SymbolTable

getSymbol

public ObjectFile.Symbol getSymbol(String name)

Specified by:

getSymbol in interface SymbolTable

getImpl

public ElementImpl getImpl()

isLoadable

public boolean isLoadable()

Description copied from class: ObjectFile.Element

Returns whether or not this section will be mapped into memory. This affects how offsets and/or vaddrs are decided.

Specified by:

isLoadable in interface ElementImpl

indexOf

public int indexOf(ObjectFile.Symbol sym)

iterator

public Iterator<ObjectFile.Symbol> iterator()

Specified by:

iterator in interface Iterable<ObjectFile.Symbol>

getEntryCount

public int getEntryCount()
