Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@StableMinor(version="16.1",

@FunctionalInterface
public interface IMonitorValuesProvider
extends java.io.Serializable
```
Interface that provides data to monitor framework when it needs.
For performance reasons, IMonitorValuesProvider implementations should guarantee that no unnecessary processing is performed (even more when it is costly) in its constructor. To be more efficient, any processing that can be postponed to getValues(SessionConfig, IMonitorField, ITransaction) should do so.
It is important to notice that getValues(SessionConfig, IMonitorField, ITransaction) may be called more than once for more than one field. Thus, implementations are highly advised to cache the results.

This interface is not considered to be thread-safe (it may be called from different threads concurrently). Implementations must guarantee thread-safety.

To ease development, AbstractMonitorValuesProvider can be used as a base implementation. It provides both, thread-safety and value caching.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`java.util.List<? extends java.io.Serializable>`	`getValues(SessionConfig sessionConfig, IMonitorField field, ITransaction transaction)`	Returns the values for the given field. If this value provider does not provide values for the given field, it must return `null`. Note that returning a `null` value is not the same as returning an empty list.

java.util.List<? extends java.io.Serializable> getValues(SessionConfig sessionConfig,
                                                         IMonitorField field,
                                                         ITransaction transaction)

```
    Returns the values for the given field.
    If this value provider does not provide values for the given field, it must return null.
    Note that returning a null value is not the same as returning an empty list. When returning an empty list, it is implied that the field has an explicit null value. When a null value is returned, then other value providers will be called. If a non-null value is returned (even an empty list), then other value providers will not be called. Any null value or empty string in the returned list will be ignored, meaning that a list with only null or empty strings will be considered an empty list.
    It is important to notice also that the given session config is not the session of the user that generated the monitoring event. Instead, it is a system user session.
    As well as session config, the given transaction is not related to the transaction that generated the event (if any).
    
    Parameters:
    
    sessionConfig - the current session.
    
    field - the desired field.
    
    transaction - the current transaction.
    
    Returns:
    
    the values for the desired field.
    
    Throws:
    
    java.lang.Exception - if some error occur.
