Class LengthConstraint

java.lang.Object
org.nuxeo.ecm.core.schema.types.constraints.AbstractConstraint
org.nuxeo.ecm.core.schema.types.constraints.LengthConstraint
All Implemented Interfaces:
Serializable, Constraint
public class LengthConstraint extends AbstractConstraint
This constraints checks whether an object's String representation size is in some interval.

This constraint's bounds are not strict (i.e. >= and <=).

Since:
7.1

  • Constructor Details

    • LengthConstraint

      public LengthConstraint(Object min, Object max)
      For a fixed length, use min = max values.

      Bounds could be any object having toString representating an integer.

      Parameters:
      min - Minimum length for the validated String, use a null value to get unbounded length.
      max - Maximum length for the validated String, use a null value to get unbounded length.

  • Method Details

    • validate

      public boolean validate(Object object)
      Description copied from interface: Constraint
      Validates the given object against this constraint.

      If some object is null. Constraint should return true while validating unless the constraint deals with nullable state.

      Parameters:
      object - the object to validate
      Returns:
      true if the object was successfully validated, false otherwise

    • getDescription

      public Constraint.Description getDescription()
      Here, value is :
      name = "LengthConstraint"
      parameters =
      • "Minimum" : 5 // only is bounded
      • "Maximum" : 10 // only if bounded
      Returns:
      The constraint description.

    • getMin

      public Long getMin()
      Returns:
      This constraints minimum length if bounded, null otherwise.
      Since:
      7.1

    • getMax

      public Long getMax()
      Returns:
      This constraints maximum length if bounded, null otherwise.
      Since:
      7.1

    • getErrorMessage

      public String getErrorMessage(Object invalidValue, Locale locale)
      Description copied from interface: Constraint
      Provides an error message to display when some invalid value does not match existing entity.
      Specified by:
      getErrorMessage in interface Constraint
      Overrides:
      getErrorMessage in class AbstractConstraint
      Parameters:
      invalidValue - The invalid value that don't match any entity.
      locale - The language in which the message should be generated.
      Returns:
      A message in the specified language or
