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.

Specified by:

setUsingCache in interface SubreportPartComponent

getParametersMapExpression

public JRExpression getParametersMapExpression()

Specified by:

getParametersMapExpression in interface SubreportPartComponent

setParametersMapExpression

public void setParametersMapExpression(JRExpression parametersMapExpression)

getParameters

public JRSubreportParameter[] getParameters()

Specified by:

getParameters in interface SubreportPartComponent

getParametersMap

public Map<String,JRSubreportParameter> getParametersMap()

addParameter

public void addParameter(JRSubreportParameter subreportParameter)
                  throws JRException

Throws:

JRException

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

public JRExpression getExpression()

Specified by:

getExpression in interface SubreportPartComponent

setExpression

public void setExpression(JRExpression expression)

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class Object

getEventSupport

public JRPropertyChangeSupport getEventSupport()

Description copied from interface: JRChangeEventsSupport

Returns the property change support object for this instance.

Specified by:

getEventSupport in interface JRChangeEventsSupport

Returns:

the property change support object for this instance
