Interface ValidationService

All Known Implementing Classes:

DefaultValidationService

public interface ValidationService

The hybris validation service validates models or Pojo's (plain old java objects) agains constraints. Use validationService.validate(yourModel) to validate this model against all constraints in the system which ARE NOT in any group (default) or use validationService.validate(yourModel, Collection<ConstraintGroupModel>) to validate this model against a configured constraint groups (which contains constraints).

Method Detail

reloadValidationEngine

void reloadValidationEngine()

Reloads the validation engine using current validation provider. After changing constraints or constraint groups this method should always be called!

validate

<T> java.util.Set<HybrisConstraintViolation> validate(T object,
                                                      java.util.Collection<ConstraintGroupModel> groups)

Validates the given model or Pojo.

If groups aren't provided - this method uses for the validation all constrains which are not in any group.

Parameters:

object - the Model or Pojo to validate

groups - A collection of constraint groups. Each group contains some constraints. Use an empty collection for validate agains the default constraints.

Returns:

a set with ConstraintViolations or an empty set if no validation was found.

Throws:

java.lang.IllegalArgumentException - if object is null or if null is passed to the groups

javax.validation.ValidationException - if a non recoverable error happens during the validation process

validate

<T> java.util.Set<HybrisConstraintViolation> validate(T object,
                                                      java.lang.Class<?>... groups)

Validates the given model or Pojo.

Same as validate(Object, Collection) but here the constraint group interfaces must be provided. If not constraint group interface is provided the default constraint group is asumed per default.

Parameters:

object - the model or pojo to validate

groups - a class array which contains the group marker interfaces.

Returns:

a set with constraint violations or an empty set if no validation was found.

validateProperty

<T> java.util.Set<HybrisConstraintViolation> validateProperty(T object,
                                                              java.lang.String propertyName,
                                                              java.util.Collection<ConstraintGroupModel> groups)

Validates all constraints placed on the property of object named propertyName.

Parameters:

groups - A collection of constraint groups. Each group contains n constraints. Use an empty collection for validate agains the default constraints.

Returns:

a set with constraint violations or an empty set if no validation was found.

Throws:

java.lang.IllegalArgumentException - if object is null, if propertyName null, empty or not a valid object property or if null is passed to the varargs groups

javax.validation.ValidationException - if a non recoverable error happens during the validation process

validateProperty

<T> java.util.Set<HybrisConstraintViolation> validateProperty(T object,
                                                              java.lang.String propertyName,
                                                              java.lang.Class<?>... groups)

Validates all constraints placed on the property of object named propertyName.

Parameters:

object - object to validate

propertyName - property to validate (ie field and getter constraints)

groups - group or list of groups targeted for validation (default to javax.validation.groups.Default )

Returns:

a set with constraint violations or an empty set if no validation was found.

Throws:

java.lang.IllegalArgumentException - if object is null, if propertyName null, empty or not a valid object property or if null is passed to the varargs groups

javax.validation.ValidationException - if a non recoverable error happens during the validation process

validateValue

<T> java.util.Set<HybrisConstraintViolation> validateValue(java.lang.Class<T> beanType,
                                                           java.lang.String propertyName,

                                                           java.util.Collection<ConstraintGroupModel> groups)

Validates all constraints placed on the property named propertyName of the class beanType would the property value be value

ConstraintViolation objects return null for ConstraintViolation.getRootBean() and ConstraintViolation.getLeafBean()

value - property value to validate

groups - A collection of constraint groups. Each group contains n constraints. Use an empty collection for validate agains the default constraints.

Returns:

constraint violations or an empty Set if none

validateValue

<T> java.util.Set<HybrisConstraintViolation> validateValue(java.lang.Class<T> beanType,
                                                           java.lang.String propertyName,

Validates all constraints placed on the property named propertyName of the class beanType would the property value be value.

ConstraintViolation objects return null for ConstraintViolation.getRootBean() and ConstraintViolation.getLeafBean().

Parameters:

beanType - the bean type

propertyName - property to validate

value - property value to validate

groups - group or list of groups targeted for validation (default to javax.validation.groups.Default )

Returns:

constraint violations or an empty Set if none

Throws:

java.lang.IllegalArgumentException - if beanType is null, if propertyName null, empty or not a valid object property or if null is passed to the varargs groups

javax.validation.ValidationException - if a non recoverable error happens during the validation process

setActiveConstraintGroups

void setActiveConstraintGroups(java.util.Collection<ConstraintGroupModel> groups)

Sets the given collection with the ConstraintGroupModels to the current session context. Those groups will be used to validate any given model during modelService.save(...).

Parameters:

groups - a collection with ConstraintGroupModel

getActiveConstraintGroups

java.util.Collection<ConstraintGroupModel> getActiveConstraintGroups()

Returns all active constraint groups which are bound to the current session.

Returns:

an empty set if no group is set

unloadValidationEngine

void unloadValidationEngine()

Method removes all constraints available for Validator, since it call no violation should be noticed.

getDefaultConstraintGroup

ConstraintGroupModel getDefaultConstraintGroup()

Returns the default constraint group (which is created during creation of eccencial data). This group displays ( ConstraintGroupModel.getConstraints()) all constraints which ARE NOT in any group. Meaning AbstractConstraintModel.getConstraintGroups() returns an empty set. Setting any constraint to this default group or adding this default group to any constraint results in a ModelSavingException! The getInterfaceName() returns always "javax.validation.groups.Default" and the Id returns always "default". Both values cannot be modified!

needReloadOfValidationEngine

boolean needReloadOfValidationEngine(AbstractConstraintModel model)

Returns true if the given constraint was modified (see ItemModel.getModifiedtime()) after the last reload (reloadValidationEngine()) of the validation engine.

Parameters:

model - the constraint

Returns:

false otherwise

validateConstraint

default void validateConstraint(AbstractConstraintModel model)

Creates TEST validation configuration using given constraint model. Does NOT influence current configuration of validation engine. When invalid constraint model is given throws ValidationException.

Parameters:

model - the constraint
