com.onec.query.Predicate
public record Predicate(Path path, Predicate.Op op, Object value, Object value2, List<?> values) extends Record
A WHERE condition on a Path. value/values carry the operands; which fields apply depends on Predicate.Op:
  • EQ NE GT GTE LT LTE LIKE use value
  • BETWEEN uses value (low) and value2 (high)
  • IN uses values
  • IS_NULL IS_NOT_NULL use no operand
Ref operands are unwrapped to their UUID at bind time by the engine.

  • Method Details

    • toString

      public final String toString()
      Returns a string representation of this record class. The representation contains the name of the class, followed by the name and value of each of the record components.

      toString in class Record
      Returns:
      a string representation of this object

    • hashCode

      public final int hashCode()
      Returns a hash code value for this object. The value is derived from the hash code of each of the record components.
      Specified by:
      hashCode in class Record
      Returns:
      a hash code value for this object

    • equals

      public final boolean equals(Object o)
      Indicates whether some other object is "equal to" this one. The objects are equal if the other object is of the same class and if all the record components are equal. All components in this record class are compared with Objects::equals(Object,Object).
      Specified by:
      equals in class Record
      Parameters:
      o - the object with which to compare
      Returns:
