  - getNestedType
```
public Class<?> getNestedType()
```
    Description copied from interface: JRParameter
    
    Returns the parameter nested value type.
    The parameter nested value type is used when the parameter value class is not sufficient in determining the expected type of the parameter values. The most common such scenario is when the parameter value class is Collection or a derived class, in which case the nested type specifies the type of values which are to be placed inside the collection.
    
    Specified by:
    
    getNestedType in interface JRParameter
    
    Returns:
    
    the nested value type for this parameter, or null if none set
    
    See Also:
    
    JRParameter.getValueClass()
  - getNestedTypeName
```
public String getNestedTypeName()
```
    Description copied from interface: JRParameter
    
    Returns the name of the parameter nested value type.
    
    Specified by:
    
    getNestedTypeName in interface JRParameter
    
    Returns:
    
    the name of the nested value type for this parameter, or null if none set

  - getEvaluationTime
```
public ParameterEvaluationTimeEnum getEvaluationTime()
```
    Description copied from interface: JRParameter
    
    Specifies when the default value expression of a parameter is evaluated.

    Specified by:
    
    hasProperties in interface JRPropertiesHolder
    
    Returns:
    
    whether the object has any properties
  - getPropertiesMap
```
public JRPropertiesMap getPropertiesMap()
```
    Description copied from interface: JRPropertiesHolder
    
    Returns this object's properties map.
    
    Specified by:
    
    getPropertiesMap in interface JRPropertiesHolder
    
    Returns:
    
    this object's properties map
  - getParentProperties
```

```
    Description copied from interface: JRPropertiesHolder
    
    Returns the parent properties holder, whose properties are used as defaults for this object.
    
    Specified by:
    
    getParentProperties in interface JRPropertiesHolder
    
    Returns:
    
    the parent properties holder, or null if no parent
  - clone

    Overrides:
    
    clone in class Object
  - getEventSupport
```
public JRPropertyChangeSupport getEventSupport()
```
    Description copied from interface: JRChangeEventsSupport
    
    Returns the property change support object for this instance.
