- Method Detail
  - getUsingCache
```
public Boolean getUsingCache()
```
    Description copied from interface: SubreportPartComponent
    
    Indicates if the engine is loading the current subreport from cache. Implementations of this method return the actual value for the internal flag that was explicitly set on this subreport.
    
    Specified by:
    
    getUsingCache in interface SubreportPartComponent
    
    Returns:
    
    Boolean.TRUE if the subreport should be loaded from cache, Boolean.FALSE otherwise or null in case the flag was never explicitly set on this subreport element
  - setUsingCache
```
public void setUsingCache(Boolean usingCache)
```
    Description copied from interface: SubreportPartComponent
    
    Specifies if the engine should be loading the current subreport from cache. If set to Boolean.TRUE, the reporting engine will try to recognize previously loaded subreports using their specified source. For example, it will recognize an subreport if the subreport source is a file name that it has already loaded, or if it is the same URL.
    If set to null, the engine will rely on some default value which depends on the type of the subreport expression. The cache is turned on by default only for subreports that have java.lang.String objects in their expressions.

  - removeParameter
```
public JRSubreportParameter removeParameter(String name)
```
  - addReturnValue
```
public void addReturnValue(JRSubreportReturnValue returnValue)
```
    Adds a return value to the subreport.
    
    Parameters:
    
    returnValue - the return value to be added.
  - getReturnValues
```
public JRSubreportReturnValue[] getReturnValues()
```
    Returns the list of values to be copied from the subreport into the master.
    
    Specified by:
    
    getReturnValues in interface SubreportPartComponent
    
    Returns:
    
    the list of values to be copied from the subreport into the master.
  - getReturnValuesList
```
public List<JRSubreportReturnValue> getReturnValuesList()
```
    Returns the list of values to be copied from the subreport into the master.
    
    Returns:
    
    list of JRSubreportReturnValue objects
  - removeReturnValue
```
public boolean removeReturnValue(JRSubreportReturnValue returnValue)
```
    Removes a return value from the subreport.
    
    Parameters:
    
    returnValue - the return value to be removed
    
    Returns:
    
    true if the return value was found and removed
  - getExpression

```
    Description copied from interface: JRChangeEventsSupport
    
    Returns the property change support object for this instance.
    
    Specified by:
    
    getEventSupport in interface JRChangeEventsSupport
    
    Returns:
