Examples of org.apache.jackrabbit.mk.model.Id

org.apache.jackrabbit.mk.model.Id
Represents an internal identifier, uniquely identifying a {@link Node} or a {@link Commit}.
This implementation aims at minimizing the in-memory footprint of an identifier instance. therefore it doesn't cache e.g. the hashCode or the string representation.
Important Note:
An {@link Id} is considered immutable. The {@code byte[]}passed to {@link Id#Id(byte[])} must not be reused or modified, the sameapplies for the {@code byte[]} returned by {@link Id#getBytes()}.
