Method Detail

isUsingCache

public boolean isUsingCache()

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

setUsingCache

public void setUsingCache(boolean isUsingCache)

Deprecated.

Description copied from interface: JRSubreport

Specifies if the engine should be loading the current subreport from cache. If set to true, the reporting engine will try to recognize previously loaded subreports using their specified source. For example, it will recognize a subreport if the subreport source is a file name that it has already loaded, or if it is the same URL.

For subreports that have expressions returning java.lang.String objects as the subreport source, representing file names, URLs or classpath resources, the default value for this flag is true.

Specified by:

setUsingCache in interface JRSubreport

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

getCopy

public JRChild getCopy(JRAbstractObjectFactory factory)

Specified by:

getCopy in interface JRChild

collectExpressions

public void collectExpressions(JRExpressionCollector collector)

Specified by:

collectExpressions in interface JRElement

writeXml

public void writeXml(JRXmlWriter xmlWriter)

Specified by:

writeXml in interface JRChild

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 java.lang.Boolean isOwnUsingCache()

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

setUsingCache

public void setUsingCache(java.lang.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
