Method Detail

getNameSpace

String getNameSpace()

getTargetType

Class getTargetType()

getValueRole

String getValueRole()

Can be one of "Value", "Resource", "Content", "Field", "Group", "Query", "Message", "Bundle-Key", "Bundle-Name", "Name", "ElementName", "DateFormat", "NumberFormat"

Returns:

isMandatory

boolean isMandatory()

isComputed

boolean isComputed()

Indicates if this attribute is computed. This indicates that values of the attribute will be computed at runtime and any value set in the element itself is merely there for caching purposes and can be removed before writing the PRPT file, before serializing and before deriving an element.

isTransient

boolean isTransient()

Indicates whether this attribute should be omitted when element is serialized to disk or written into a PRPT file. Only mark attributes as transient which contain values that have been handled elsewhere.

isBulk

boolean isBulk()

isDesignTimeValue

boolean isDesignTimeValue()

Indicates whether this attribute is a design-time value. Such values will not be computed at runtime and any expression given for that attribute will be ignored.

Returns:

getEditor

PropertyEditor getEditor()

This method can return null if there is no property editor registered for this type.

Returns:

getReferencedFields

String[] getReferencedFields(ReportElement element,
                             Object attributeValue)

getReferencedGroups

String[] getReferencedGroups(ReportElement element,
                             Object attributeValue)

getReferencedResources

ResourceReference[] getReferencedResources(ReportElement element,
                                           org.pentaho.reporting.libraries.resourceloader.ResourceManager resourceManager,
                                           Object attributeValue)

getExtraCalculationFields

String[] getExtraCalculationFields()
