Field Detail

NO_OFFSET

private static final int NO_OFFSET

Initial value for a field offset - indicates field not laid out.

See Also:: Constant Field Values

declaringClass

private final TypeReference declaringClass

The class that declared this member, available by calling getDeclaringClass once the class is loaded.

memRef

protected final MemberReference memRef

The canonical MemberReference for this member

modifiers

protected final short modifiers

The modifiers associated with this member.

signature

private final Atom signature

The signature is a string representing the generic type for this field or method declaration, may be null

offset

protected int offset

The member's jtoc/obj/tib offset in bytes. Set by RVMClass.resolve()

Constructor Detail

RVMMember

protected RVMMember(TypeReference declaringClass,
                    MemberReference memRef,
                    short modifiers,
                    Atom signature,
                    RVMAnnotation[] annotations)

NOTE: Only RVMClass is allowed to create an instance of a RVMMember.

Parameters:: declaringClass - the TypeReference object of the class that declared this member; memRef - the canonical memberReference for this member.; modifiers - modifiers associated with this member.; signature - generic type of this member; annotations - array of runtime visible annotations

Method Detail

getDeclaringClass

public final RVMClass getDeclaringClass()

Class that declared this field or method. Not available before the class is loaded.

getMemberRef

public final MemberReference getMemberRef()

Canonical member reference for this member.

getName

public final Atom getName()

Name of this member.

getDescriptor

public final Atom getDescriptor()

Descriptor for this member. something like "I" for a field or "(I)V" for a method.

getSignature

public final Atom getSignature()

Generic type for member

getId

public final int getId()

Get a unique id for this member. The id is the id of the canonical MemberReference for this member and thus may be used to find the member by first finding the member reference.

hashCode

public int hashCode()

Overrides:: hashCode in class Object

toString

public final String toString()

Overrides:: toString in class Object

isPublic

public final boolean isPublic()

Usable from classes outside its package?

isPrivate

public final boolean isPrivate()

Usable only from this class?

isProtected

public final boolean isProtected()

Usable from subclasses?

getModifiers

public final int getModifiers()

Get the member's modifiers.

hasOffset

public final boolean hasOffset()

Has the field been laid out in the object yet ?

Returns:: true if the field has been assigned an offset, false if not

getOffset

public final Offset getOffset()

Offset of this field or method, in bytes.

For a static field: offset of field from start of jtoc
For a static method: offset of code object reference from start of jtoc
For a non-static field: offset of field from start of object
For a non-static method: offset of code object reference from start of tib

setOffset

public final void setOffset(Offset off)

Only meant to be used by ObjectModel.layoutInstanceFields. TODO: refactor system so this functionality is in the classloader package and this method doesn't have to be final.
