IsEmptyPlugin (SQL Processor, Core Module 3.5.1 API)

All Superinterfaces:

Modifiers

All Known Implementing Classes:

DefaultSqlPlugins
```
public interface IsEmptyPlugin
extends Modifiers
```
The SQL Processor plugin devoted to evaluate the emptiness of the input value.
The emptiness is the basic facility in the construction of the final SQL statements from the META SQL fragments.
The standard evaluation is the next one:
The non-emptiness of a dynamic input value depends on the Java type of the related attribute
- for a String it must be not null and the length must be >0
- for a Collection it must be not null and the size must be >0
- for the rest Java types it must be not null
- an enumeration based attribute is treated in a special way, please see the advanced tutorial

```
    Used for the evaluation of the emptiness in the META SQL fragments.
    
    Parameters:
    
    runtimeCtx - the public runtime context
    
    attributeName - the name of the input value
    
    obj - the input value
    
    parentObj - the parent of the input value
    
    sqlMetaType - the internal type (= META type) devoted for the special processing of the input values
    
    inOutModifier - the input/output value modifier devoted to extend the processing of the input/output values
    
    inSqlSetOrInsert - an indicator the input value is evaluated in the CRUD statement (INSERT or SET)
    
    values - values for a special identifier handling, for example a sequence for an identity
    
    Returns:
    
    the non-emptiness of the input value
