Annotation Type AssertTrue

@Documented
@Retention(value=RUNTIME)
@Target(value={FIELD,PARAMETER,METHOD})
@Constraint(checkWith=AssertTrueCheck.class)
public @interface AssertTrue

Check if the value is true.

Note: This constraint is also satisified when the value to validate is null, therefore you might also need to specified @NotNull

appliesTo

public abstract ConstraintTarget[] appliesTo

In case the constraint is declared for an array, collection or map this controls how the constraint is applied to it and it's child objects.

Default: ConstraintTarget.VALUES

Note: This setting is ignored for object types other than array, map and collection.

Default:

VALUES

errorCode

public abstract String errorCode

error code passed to the ConstraintViolation object

Default:

"net.sf.oval.constraint.AssertTrue"

message

public abstract String message

message to be used for the ContraintsViolatedException

See Also:

ConstraintViolation

Default:

"net.sf.oval.constraint.AssertTrue.violated"

profiles

public abstract String[] profiles

The associated constraint profiles.

Default:

{}

severity

public abstract int severity

severity passed to the ConstraintViolation object

Default:

0

target

public abstract String target

An expression to specify where in the object graph relative from this object the expression should be applied.

Examples:

"owner" would apply this constraint to the current object's property owner

"owner.id" would apply this constraint to the current object's owner's property id

"jxpath:owner/id" would use the JXPath implementation to traverse the object graph to locate the object where this constraint should be applied.

Default:

""

when

public abstract String when

Formula returning true if this constraint shall be evaluated and false if it shall be ignored for the current validation.

Important: The formula must be prefixed with the name of the scripting language that is used. E.g. groovy:_this.amount > 10

Available context variables are:
_this -> the validated bean
_value -> the value to validate (e.g. the field value, parameter value, method return value, or the validated bean for object level constraints)

Default:

""
