Class ObjectFile.Element

java.lang.Object

com.oracle.objectfile.ObjectFile.Element

All Implemented Interfaces:

ElementImpl

Direct Known Subclasses:

ELFObjectFile.SectionHeaderTable, MachOStrtab, MachOSymtab, ObjectFile.Header, ObjectFile.Section, PECoffObjectFile.SectionHeaderTable, PECoffRelocationTable, PECoffSymtab

Enclosing class:

ObjectFile

public abstract class ObjectFile.Element
extends Object
implements ElementImpl

All headers and sections are subclasses of ObjectFile.Element. It is an inner class, meaning that every Element has an associated ObjectFile.

Constructor Detail

Element

public Element(String name)

Element

public Element(String name,
               int alignment)

Constructs an element with the given name and index in the element list. If no particular index is desired, it may be passed as -1.

Parameters:

name -

alignment -

Method Detail

toString

public String toString()

Overrides:

toString in class Object

setElement

public void setElement(ObjectFile.Element element)

Specified by:

setElement in interface ElementImpl

getAlignment

public int getAlignment()

Specified by:

getAlignment in interface ElementImpl

getElement

public final ObjectFile.Element getElement()

Specified by:

getElement in interface ElementImpl

getImpl

public abstract ElementImpl getImpl()

getName

public String getName()

This method can be overridden.

getElementName

public final String getElementName()

This method can not be overridden.

getOwner

public ObjectFile getOwner()

isLoadable

public abstract boolean isLoadable()

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

isReferenceable

public boolean isReferenceable()

Description copied from interface: ElementImpl

Locations in this section are referenceable by symbol names, section names, or by relocation, so the section needs a virtual address. Generally applies to loadable sections, but can also be used to enable references into sections that are not loadable, such as debug sections.

Specified by:

isReferenceable in interface ElementImpl

getDecisions

public abstract LayoutDecisionMap getDecisions(LayoutDecisionMap copyingIn)

Specified by:

getDecisions 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
