Interface DFFieldPickListCapability.FieldBridge

Enclosing class:

DFFieldPickListCapability

public static interface DFFieldPickListCapability.FieldBridge

This is an interface playing role of a bridge between this capability and the field's implementation. Some operations cannot be handled in DFFieldPickListCapability, but must be delegated to a field. Once field creates this capability instance it must provide the implementation of the this interface. You should probably never need to implement this interface.

Method Detail

checkLock

void checkLock(com.im.commons.progress.DFEnvironmentRW env)

Checks the lock before doing write operations. All setters of DFFieldPickListCapability should be guarded by DDL's lock. See DFLockable.

Parameters:

env - The environment with the DDL lock

load

java.util.Properties load()

Loads properties of this DFFieldPickListCapability. Used by persistence.

Returns:

Properties instance with values for this capability (e.g. picklist type).

store

void store(java.util.Properties propsToSet,
           java.util.Set<java.lang.String> propsToClear,
           com.im.commons.progress.DFEnvironmentRW env)

Stores the internal state of this DFFieldPickListCapability. Used by persistence.

Parameters:

propsToSet - Properties to store

propsToClear - Properties to clear

env - Environment with DDL lock

executeScript

java.util.List executeScript(java.lang.String loaderScript)

Executes the loader script. See more info about loader scripts here: DFFieldPickListCapability.setLoaderScript(java.lang.String, com.im.commons.progress.DFEnvironmentRW).

Parameters:

loaderScript - The script to be executed.

Returns:

Values from the script execution.

firePropertyChangeEvent

void firePropertyChangeEvent(java.lang.String propName,
                             java.lang.Object oldValue,
                             java.lang.Object newValue)

Fires property changes from this DFFieldPickListCapability. Field which owns this capability should fire these property changes to its registered listeners. See PROP_ constants in this class.

Parameters:

propName - Property name

oldValue - Old property value

newValue - New property value

updatePickList

void updatePickList()

Updates fields pick-list values.
