Annotation Type NotEqual


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

Check if the string representation does not equal a given string.

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

Element Detail

value

public abstract String value

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.NotEqual"

ignoreCase

public abstract boolean ignoreCase
Default:
false

message

public abstract String message
message to be used for the ContraintsViolatedException

See Also:
ConstraintViolation
Default:
"net.sf.oval.constraint.NotEqual.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:
    ""
