                          JRBaseObjectFactory factory)

Method Detail

getModeValue

public ModeEnum getModeValue()

Description copied from interface: JRCommonElement

Returns the element transparency mode. The default value depends on the type of the report element. Graphic elements like rectangles and lines are opaque by default, but the images are transparent. Both static texts and text fields are transparent by default, and so are the subreport elements.

Specified by:

getModeValue in interface JRCommonElement

Overrides:

getModeValue in class JRBaseElement

isUsingCache

public boolean isUsingCache()

Deprecated. Replaced by getUsingCache().

Description copied from interface: JRSubreport

Indicates if the engine is loading the current subreport from cache. Implementations of this method rely on default values that depend on the type of the subreport expression if a value was not explicitly set of this flag.

Specified by:

isUsingCache in interface JRSubreport

Returns:

true if the subreport should be loaded from cache, false otherwise

getParametersMapExpression

public JRExpression getParametersMapExpression()

Specified by:

getParametersMapExpression in interface JRSubreport

getParameters

public JRSubreportParameter[] getParameters()

Specified by:

getParameters in interface JRSubreport

getConnectionExpression

public JRExpression getConnectionExpression()

Specified by:

getConnectionExpression in interface JRSubreport

getDataSourceExpression

public JRExpression getDataSourceExpression()

Specified by:

getDataSourceExpression in interface JRSubreport

getExpression

public JRExpression getExpression()

Specified by:

getExpression in interface JRSubreport

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElement

visit

public void visit(JRVisitor visitor)

Specified by:

visit in interface JRVisitable

getReturnValues

public JRSubreportReturnValue[] getReturnValues()

Returns the list of values to be copied from the subreport into the master.

Specified by:

getReturnValues in interface JRSubreport

Returns:

the list of values to be copied from the subreport into the master.

isOwnUsingCache

public Boolean isOwnUsingCache()

Deprecated. Replaced by getUsingCache().

Description copied from interface: JRSubreport

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:

isOwnUsingCache in interface JRSubreport

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

getUsingCache

public Boolean getUsingCache()

Description copied from interface: JRSubreport

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 JRSubreport

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 isUsingCache)

Description copied from interface: JRSubreport

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 JRSubreport

isRunToBottom

public Boolean isRunToBottom()

Description copied from interface: JRSubreport

Specifies whether the subreport element will consume the entire vertical space available on the report page.

Specified by:

isRunToBottom in interface JRSubreport

Returns:

whether the subreport element will consume the entire space down to the bottom of the page

See Also:

JRSubreport.setRunToBottom(Boolean)

setRunToBottom

public void setRunToBottom(Boolean runToBottom)

Description copied from interface: JRSubreport

Sets the flag that Specifies whether the subreport element will consume the entire vertical space available on the report page.

This flag should be set to true if the subreport needs to always print its column and page footers at the bottom of the report page, even when the subreport data does not stretch to the bottom.

Note that when isFloatColumnFooter is set for the subreport, the column footers will not be printed at the bottom of the page even if this flag is set.

Specified by:

setRunToBottom in interface JRSubreport

Parameters:

runToBottom - whether the subreport element will consume the entire space down to the bottom of the page

clone

public Object clone()

Specified by:

clone in interface JRCloneable

Overrides:

clone in class JRBaseElement
