Examples of org.jbpm.bytes.ByteArray

org.jbpm.bytes.ByteArray
is a persistable array of bytes. While there is no generic way of storing blobs that is supported by many databases, all databases are able to handle small chunks of bytes properly. It is the responsibility of this class to chop the large byte array into small chunks of 1K (and combine the chunks again in the reverse way). Hibernate will persist the list of byte-chunks in the database. ByteArray is used in process variableInstances and in the file module (that stores the non-parsed process archive files).
