Class Field<T>

java.lang.Object

org.aspectj.org.eclipse.jdt.internal.core.nd.field.Field<T>

Type Parameters:

T -

All Implemented Interfaces:

IDestructableField, IField

public final class Field<T>
extends java.lang.Object
implements IField, IDestructableField

Used to represent a single field of an object stored in the database. Objects which store themselves in the database should store a set of static final FieldDefinitions at the top of their class definition to indicate their memory map. This serves as a standard way to document the memory map for such structs, provides access to the field offsets, and provides a convenience getter.

There are two ways to use this. Callers can either use the "get" method to access the value of the field, or can use the public "offset" attribute to perform the reads manually. The get function is more convenient but allocates objects and so should probably not be used for frequently-accessed fields or primitive types that would end up being autoboxed unnecessarily.
