Constructor Detail

PECoffSymtab

public PECoffSymtab(PECoffObjectFile owner,
                    String name)

PECoffSymtab Element encompases the Symbol table array and the String table. The String table immediately follows the Symbol table.

Method Detail

getImpl

public ElementImpl getImpl()

Specified by:

getImpl in class ObjectFile.Element

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

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

Specified by:

isLoadable in class ObjectFile.Element

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

getNullEntry

public com.oracle.objectfile.pecoff.PECoffSymtab.Entry getNullEntry()

indexOf

public int indexOf(ObjectFile.Symbol sym)

iterator

public Iterator<ObjectFile.Symbol> iterator()

Specified by:

getSymbol

public com.oracle.objectfile.pecoff.PECoffSymtab.Entry getSymbol(String name)

Specified by:

getSymbol in interface SymbolTable

getSymbolCount

public int getSymbolCount()

getDirectiveSize

public int getDirectiveSize()

getDirectiveArray

public byte[] getDirectiveArray()

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.
