Method Detail

init

public void init(boolean dbOnly,
                 java.util.Dictionary p)

Description copied from interface: org.apache.derby.iapi.services.property.PropertySetCallback

Initialize the properties for this callback. Called when addPropertySetNotification() is called with a non-null transaction controller. This allows code to set read its initial property values at boot time.

Code within an init() method should use the 3 argument PropertyUtil method getPropertyFromSet() to obtain a property's value.

Specified by:

init in interface org.apache.derby.iapi.services.property.PropertySetCallback

validate

public boolean validate(java.lang.String key,
                        java.io.Serializable value,
                        java.util.Dictionary p)
                 throws org.apache.derby.iapi.error.StandardException

Description copied from interface: org.apache.derby.iapi.services.property.PropertySetCallback
