Method Detail

writePayload

protected abstract void writePayload(OutputAssembler out,
                                     Map<ObjectFile.Element,LayoutDecisionMap> alreadyDecided)

getOwner

public MachOObjectFile getOwner()

Overrides:

getOwner 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

Overrides:

getOrDecideContent in class ObjectFile.Header

getWrittenSize

protected int getWrittenSize(int payloadSize)

Get the size of this load command, given a particular payload size. Subclasses can use this to compute the overall size. This allows them to avoid a dependency from content to size, which our default dependencies include. We use this in MachOObjectFile.SymtabCommand to avoid creating cyclic dependencies.

Parameters:

payloadSize - the size on disk, in bytes, of the payload part of the load command

Returns:

the size on disk, in bytes, of the load command as a whole
