Method Detail

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

getImpl

public final ElementImpl getImpl()

Specified by:

getImpl in class ObjectFile.Element

getDecisions

public LayoutDecisionMap getDecisions(LayoutDecisionMap copyingIn)

Specified by:

getDecisions in interface ElementImpl

Specified by:

getDecisions in class ObjectFile.Element

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

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.

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.

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.

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()).
