An integer allowing users to limit the datasource size.

See Also:

Constant Field Values

REPORT_DATA_SOURCE

static final java.lang.String REPORT_DATA_SOURCE

A JRDataSource instance representing the report data source. JasperReports defines some convenience implementations of JRDataSource, but users may create their own data sources for specific needs.

See Also:

Constant Field Values

REPORT_SCRIPTLET

static final java.lang.String REPORT_SCRIPTLET

A JRAbstractScriptlet containing an instance of the report scriptlet provided by the user.

See Also:

Constant Field Values

REPORT_LOCALE

static final java.lang.String REPORT_LOCALE

A java.util.Locale instance containing the resource bundle desired locale. This parameter should be used in conjunction with REPORT_RESOURCE_BUNDLE.

See Also:

Constant Field Values

REPORT_RESOURCE_BUNDLE

static final java.lang.String REPORT_RESOURCE_BUNDLE

The java.util.ResourceBundle containing localized messages. If the resource bundle base name is specified at design time, the engine will try to load the resource bundle using specified name and locale.

See Also:

Constant Field Values

REPORT_TIME_ZONE

static final java.lang.String REPORT_TIME_ZONE

A java.util.TimeZone instance to use for date formatting.

See Also:

Constant Field Values

REPORT_VIRTUALIZER

static final java.lang.String REPORT_VIRTUALIZER

The JRVirtualizer to be used for page virtualization. This parameter is optional.

See Also:

Constant Field Values

REPORT_CLASS_LOADER

static final java.lang.String REPORT_CLASS_LOADER

Deprecated. Replaced by JasperReportsContext.

A java.lang.ClassLoader instance to be used during the report filling process to load resources such as images, fonts and subreport templates.

See Also:

Constant Field Values

REPORT_URL_HANDLER_FACTORY

static final java.lang.String REPORT_URL_HANDLER_FACTORY

Deprecated. Replaced by JasperReportsContext.

A java.net.URLStreamHandlerFactory instance to be used during the report filling process to handle custom URL protocols for loading resources such as images, fonts and subreport templates.

See Also:

Constant Field Values

REPORT_FILE_RESOLVER

static final java.lang.String REPORT_FILE_RESOLVER

Deprecated. Replaced by JasperReportsContext.

A FileResolver instance to be used during the report filling process to handle locate files on disk using relative paths.

See Also:

Constant Field Values

REPORT_FORMAT_FACTORY

static final java.lang.String REPORT_FORMAT_FACTORY

A FormatFactory instance to be used during the report filling process to create instances of java.text.DateFormat to format date text fields and instances of java.text.NumberFormat to format numeric text fields.

See Also:

Constant Field Values

IS_IGNORE_PAGINATION

static final java.lang.String IS_IGNORE_PAGINATION

Whether to use pagination.

If set to true the report will be generated on one long page.

See Also:

Constant Field Values

REPORT_TEMPLATES

static final java.lang.String REPORT_TEMPLATES

A collection of templates passed to the report at fill time.

These templates add to the ones specified in the report (see JRReport.getTemplates()). In the final templates list they are placed after the report templates; therefore styles from these templates can use and override styles in the report templates. They are, however, placed before the report styles hence report styles can use and override styles from these templates.

Method Detail

getName

java.lang.String getName()

getDescription

java.lang.String getDescription()

setDescription

void setDescription(java.lang.String description)

getValueClass

java.lang.Class<?> getValueClass()

getValueClassName

java.lang.String getValueClassName()

isSystemDefined

boolean isSystemDefined()

isForPrompting

boolean isForPrompting()

getDefaultValueExpression

JRExpression getDefaultValueExpression()

getNestedType

java.lang.Class<?> getNestedType()

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.

Returns:

the nested value type for this parameter, or null if none set

See Also:

getValueClass()

getNestedTypeName

java.lang.String getNestedTypeName()

Returns the name of the parameter nested value type.

Returns:

the name of the nested value type for this parameter, or null if none set
