Interface PropertyValidatorFactory

All Known Implementing Classes:
JsonSchemaPropertyValidatorFactory
Functional Interface:
This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.
@FunctionalInterface public interface PropertyValidatorFactory
Builds PropertyValidator instances from a JSON-Schema-shaped map of constraints.

The factory is resolved at runtime via ServiceLoader through PropertyValidators.factory(). If no factory is on the classpath (i.e. juneau-bean-jsonschema is not present), schema-validation mode silently becomes a no-op.

The marshalling side calls the factory once per bean property at BeanMeta construction time and installs the resulting validator into the property's read/write transform slots.

Thread safety
Factory implementations must be safe to invoke from multiple threads concurrently.

    • create

      PropertyValidator create(Map<String,Object> schemaMap, Class<?> propertyType)
      Builds a validator from a JSON-Schema-shaped map of constraints.
      Parameters:
      schemaMap - A map mirroring the JSON Schema constraint shape (the same shape produced by SchemaAnnotation.asMap()). May be empty, in which case implementations should return null.
      propertyType - The Java type of the property being validated. May be used by the factory to choose narrower numeric or collection validators. May be null.
      Returns:
      A validator, or null if the map carries no actionable constraints.
