Example 1 with ObjToByteArraySerializer

use of org.apache.geode.internal.ObjToByteArraySerializer in project geode by apache.

the class DataSerializer method writeObjectAsByteArray.

/**
   * Serialize the given object <code>obj</code> into a byte array using
   * {@link #writeObject(Object, DataOutput)} and then writes the byte array to the given data
   * output <code>out</code> in the same format {@link #writeByteArray(byte[], DataOutput)} does.
   * This method will serialize a <code>null</code> obj and not throw a
   * <code>NullPointerException</code>.
   *
   * @param obj the object to serialize and write
   * @param out the data output to write the byte array to
   * @throws IllegalArgumentException if a problem occurs while serialize <code>obj</code>
   * @throws IOException if a problem occurs while writing to <code>out</code>
   *
   * @see #readByteArray
   * @since GemFire 5.0.2
