retrieve

void retrieve(java.sql.Connection aConn,

              throws java.sql.SQLException

This method allows the implemented object to retrieve its state from the persistent store.

Parameters:

aConn - The Connection on which to execute SQL statements. It should be an open connection and the implementation should refrain from closing it, so the caller can reuse it.

aHMKeys - HashMap with the 'key-value' pairs necessary for the construction of the primary key to be retrieved.

Throws:

java.sql.SQLException - When the retrieve fails (e.g.: PK not found).
