Note that this is a critically important part of equality. As Rich - * Hickey notes: - * - * … the only things you can really compare for equality are immutable things, - * because if you compare two things for equality that are mutable, and ever - * say true, and they're ever not the same thing, you are wrong. Or you will - * become wrong at some point in the future. - * - * Records have a layered definition of equality. Two records can be said to be - * "equal" if: - * - * * They have the same GUID and collection. Two crypto/keys records are in some - * way "the same". - * This is `equalIdentifiers`. - * - * * Their most significant fields are the same. That is to say, they share a - * GUID, a collection, deletion, and domain-specific fields. Two copies of - * crypto/keys, neither deleted, with the same encrypted data but different - * modified times and sortIndex are in a stronger way "the same". - * This is `equalPayloads`. - * - * * Their most significant fields are the same, and their local fields (e.g., - * the androidID to which we have decided that this record maps) are congruent. - * A record with the same androidID, or one whose androidID has not been set, - * can be considered "the same". - * This concept can be extended by Record subclasses. The key point is that - * reconciling should be applied to the contents of these records. For example, - * two history records with the same URI and GUID, but different visit arrays, - * can be said to be congruent. - * This is `congruentWith`. - * - * * They are strictly identical. Every field that is persisted, including - * lastModified and androidID, is equal. - * This is `equals`. - * - * Different parts of the codebase have use for different layers of this - * comparison hierarchy. For instance, lastModified times change every time a - * record is stored; a store followed by a retrieval will return a Record that - * shares its most significant fields with the input, but has a later - * lastModified time and might not yet have values set for others. Reconciling - * will thus ignore the modification time of a record. - * - * @author rnewman - * - */ -public abstract class Record { - - public String guid; - public String collection; - public long lastModified; - public boolean deleted; - public long androidID; - /** - * An integer indicating the relative importance of this item in the collection. - * <p> - * Default is 0. - */ - public long sortIndex; - /** - * The number of seconds to keep this record.
