  - constraintModes
```
private java.util.HashMap<UUID,java.lang.Boolean> constraintModes
```
    Maps a constraint id (key) into a Boolean for deferrable constraints. If the Boolean value is FALSE, we have immediate checking, if it is TRUE we have deferred checking. Cf. SQL SET CONSTRAINT.
  - deferredAll
```
private java.lang.Boolean deferredAll
```
    True if all deferrable constraints are deferred in this transaction.

```
public java.util.HashMap<UUID,java.lang.Boolean> getConstraintModes()
```
    Get a handle to the session's constraint modes. The caller is responsible for any cloning needed.
    
    Specified by:
    
    getConstraintModes in interface SQLSessionContext
    
    Returns:
    
    constraint modes map
  - setConstraintModes
```
public void setConstraintModes(java.util.HashMap<UUID,java.lang.Boolean> hm)
```
    Initialize a inferior session context with the constraint mode map of the parent session context.
    
    Specified by:
    
    setConstraintModes in interface SQLSessionContext
    
    Parameters:
    
    hm - constraint mode map
  - setDeferred
```
public void setDeferred(UUID constraintId,
                        boolean deferred)
```
    Set the constraint mode for this constraint to deferred. If deferred is false, to immediate checking, if true to deferred checking.
    
    Specified by:
    
    setDeferred in interface SQLSessionContext
    
    Parameters:
    
    constraintId - The constraint id
    
    deferred - The new constraint mode
  - isDeferred
```
public java.lang.Boolean isDeferred(UUID constraintId)
```
    Return Boolean.TRUE if the constraint mode for this constraint/index has been set to deferred, Boolean.FALSE if it has been set to immediate. Any ALL setting is considered also. If the constraint mode hasn't been set for this constraint, return null. The constraint mode is the effectively the initial constraint mode in this case.
    
    Specified by:
    
    isDeferred in interface SQLSessionContext
    
    Parameters:
    
    constraintId - the constraint id
    
    Returns:
    
    Boolean.TRUE if the constraint mode for this constraint/index has been set to deferred, Boolean.FALSE if it has been set to immediate.
  - resetConstraintModes
```
public void resetConstraintModes()
```
    Clear deferred information for this transaction.
    
    Specified by:
    
    resetConstraintModes in interface SQLSessionContext
  - setDeferredAll
```
public void setDeferredAll(java.lang.Boolean deferred)
```
    Set the constraint mode for all deferrable constraints to deferred. If deferred is false, set to immediate checking, if true to deferred checking. null is allowed: it means no ALL setting exists.
    
    Specified by:
    
    setDeferredAll in interface SQLSessionContext
    
    Parameters:
    
    deferred - the mode to set
  - getDeferredAll
```
public java.lang.Boolean getDeferredAll()
```
    Get state of DEFERRED ALL setting.
    
    Specified by:
    
    getDeferredAll in interface SQLSessionContext
    
    Returns:
    
    True is deferred all constraint mode has been set for this session context. False is deferred immediate has been set for this session context. null means no ALL setting has been made for this context
