| DNA | | public interface DNA (Code) | | Represents the data of an object. Implementations of this interface are used to extract data from and apply
(new/updated) data to objects. It's like serialization data, but it allows deltas to be extracted and applied.

| NULL_ARRAY_SIZE | | final public static int NULL_ARRAY_SIZE(Code) | | Array size constant indicating no array size
|

|
| getCursor | | public DNACursor getCursor()(Code) | | Gets a DNACursor to spin through the field values.
The cursor |
| getDefiningLoaderDescription | | public String getDefiningLoaderDescription()(Code) | | Get defining classloader name
Classloader name |
| getObjectID | | public ObjectID getObjectID() throws DNAException(Code) | | Gets the id of the object represented by this DNA strand. The id is globally unique.
TODO: Potentially change the type from long to something which can be a composite key. We want to be able to
generate new ids in the local VM without making a round trip to the object service.
The id in question
throws:
DNAException - Exception thrown if the id cannot be resolved from the DNA strand. |
| getParentObjectID | | public ObjectID getParentObjectID() throws DNAException(Code) | | If this object is an inner class, get the parent object identifier
The parent object if one exists
throws:
DNAException - Exception thrown if the id cannot be resolved |
| getTypeName | | public String getTypeName()(Code) | | Get the class name of the type for this piece of DNA
Class name |
| getVersion | | public long getVersion()(Code) | | Get the version of this DNA based on the global transaction ID,
may be
DNA.NULL_VERSION .
|
| hasLength | | public boolean hasLength()(Code) | | Determine whether this DNA has an array length
True if has length |
| isDelta | | public boolean isDelta()(Code) | | Determine whether this DNA is a whole object or just a delta
true if the DNA represents a change of an object andfalse if the DNA represents the entire object. |
