Method Detail

getImpl

public ElementImpl getImpl()

Specified by:

getImpl in class ObjectFile.Element

getEntrySize

public int getEntrySize()

Overrides:

getEntrySize in class ELFObjectFile.ELFSection

getLinkedSection

public ELFObjectFile.ELFSection getLinkedSection()

Overrides:

getLinkedSection in class ELFObjectFile.ELFSection

getLinkedInfo

public long getLinkedInfo()

Overrides:

getLinkedInfo in class ELFObjectFile.ELFSection

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

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

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

isDynamic

public boolean isDynamic()

newDefinedEntry

public ObjectFile.Symbol newDefinedEntry(String name,
                                         ObjectFile.Section referencedSection,
                                         long referencedOffset,
                                         long size,

                                         boolean isCode)

Specified by:

newDefinedEntry in interface SymbolTable

newUndefinedEntry

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

Specified by:

newUndefinedEntry in interface SymbolTable

getNullEntry

public com.oracle.objectfile.elf.ELFSymtab.Entry getNullEntry()

indexOf

public int indexOf(ObjectFile.Symbol sym)

iterator

public Iterator<ObjectFile.Symbol> iterator()

Specified by:

getOrDecideOffset

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