Method Detail

mapDetailsToBeanProperties

public static void mapDetailsToBeanProperties(FeatureDescriptor descriptor,
                                              java.lang.Object bean,
                                              org.databene.commons.Context context)

mapDetailToBeanProperty

public static void mapDetailToBeanProperty(FeatureDescriptor descriptor,
                                           java.lang.String detailName,
                                           java.lang.Object bean,
                                           org.databene.commons.Context context)

setBeanProperty

public static void setBeanProperty(java.lang.Object bean,
                                   java.lang.String detailName,
                                   java.lang.Object detailValue,
                                   org.databene.commons.Context context)

getDistribution

public static Distribution getDistribution(java.lang.String spec,
                                           Uniqueness uniqueness,
                                           boolean required,
                                           BeneratorContext context)

Extracts distribution information from the descriptor.

Parameters:

spec - the textual representation of the distribution

uniqueness - tells if a unique distribution is requested

required - if set the method will never return null

context - the BeneratorContext

Returns:

a distribution that reflects the descriptor setup, null if distribution info is not found nor required.

getDistributionExpression

public static org.databene.commons.Expression<Distribution> getDistributionExpression(java.lang.String spec,
                                                                                      Uniqueness uniqueness,
                                                                                      boolean required)

getCountGenerator

public static Generator<java.lang.Long> getCountGenerator(InstanceDescriptor descriptor,
                                                          boolean resetToMin)

createCyclicHeadGenerator
