Example 14 with RepositoryException

use of javax.jcr.RepositoryException in project jackrabbit by apache.

the class BundleWriter method writeState.

/**
     * Serializes a property entry. The serialization begins with the
     * property name followed by a single byte that encodes the type and
     * multi-valuedness of the property:
     * <pre>
     * +-------------------------------+
     * |   mv count    |     type      |
     * +-------------------------------+
     * </pre>
     * <p>
     * The lower four bits encode the property type (0-12 in JCR 2.0) and
     * higher bits indicate whether this is a multi-valued property and how
     * many property values there are. A value of 0 is reserved for
     * single-valued properties (that are guaranteed to always have just a
     * single value), and all non-zero values indicate a multi-valued property.
     * <p>
     * In multi-valued properties the exact value of the "mv count" field is
     * the number of property values plus one and truncated at 15 (the highest
     * four-bit value). If there are 14 or more (14 + 1 == 15) property values,
     * then the number of additional values is serialized as a variable-length
     * integer (see {@link #writeVarInt(int)}) right after this byte.
     * <p>
     * The modification count of the property state is written next as a
     * variable-length integer, followed by the serializations of all the
     * values of this property.
     *
     * @param state the property entry to store
     * @throws IOException if an I/O error occurs.
