Class BasicNobitsSectionImpl

java.lang.Object

com.oracle.objectfile.BasicElementImpl

com.oracle.objectfile.BasicNobitsSectionImpl

All Implemented Interfaces:

ElementImpl, ObjectFile.NobitsSectionImpl

public class BasicNobitsSectionImpl
extends BasicElementImpl
implements ObjectFile.NobitsSectionImpl

This represents the core of a nobits/zerofill section, in any object file format. By default it delegates to an underlying Section object, of some format-specific class.

Method Detail

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

Overrides:

getDependencies in class BasicElementImpl

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

Overrides:

getOrDecideSize in class BasicElementImpl

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

getMemSize

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

Description copied from interface: ElementImpl

Implement this method to provide the section size in memory (at runtime).

Specified by:

getMemSize in interface ElementImpl

Overrides:

getMemSize in class BasicElementImpl

getSizeInMemory

public long getSizeInMemory()

Specified by:

getSizeInMemory in interface ObjectFile.NobitsSectionImpl

setSizeInMemory

public void setSizeInMemory(long size)

Specified by:

setSizeInMemory in interface ObjectFile.NobitsSectionImpl

getAlignment

public int getAlignment()

Specified by:

getAlignment in interface ElementImpl

Overrides:

getAlignment in class BasicElementImpl

isLoadable

public boolean isLoadable()

Description copied from interface: ElementImpl

Whether this section is loaded into memory at runtime.

Specified by:

isLoadable in interface ElementImpl
