protected java.util.Vector |
createVector(java.lang.Number sequence,
java.lang.String seqName,
int size)
INTERNAL: given sequence = 10, size = 5 will create Vector (6,7,8,9,10) |
java.lang.Object |
getGeneratedValue(org.eclipse.persistence.internal.databaseaccess.Accessor accessor,
org.eclipse.persistence.internal.sessions.AbstractSession writeSession,
java.lang.String seqName)
INTERNAL: Return the newly-generated sequencing value. |
java.util.Vector |
getGeneratedVector(org.eclipse.persistence.internal.databaseaccess.Accessor accessor,
org.eclipse.persistence.internal.sessions.AbstractSession writeSession,
java.lang.String seqName,
int size)
INTERNAL: Return a Vector of newly-generated sequencing values. |
void |
onConnect()
INTERNAL: This method is called when Sequencing object is created. |
void |
onDisconnect()
INTERNAL: This method is called when Sequencing object is destroyed. |
void |
setInitialValue(int initialValue)
|
abstract boolean |
shouldAcquireValueAfterInsert()
INTERNAL: Indicates whether sequencing value should be acquired after INSERT. |
abstract boolean |
shouldUseTransaction()
INTERNAL: Indicates whether TopLink should internally call beginTransaction() before getGeneratedValue/Vector, and commitTransaction after. |
