Concrete methods

override def equals(o: Any): Boolean

Compares the receiver object (this) with the argument object (that) for equivalence.

Compares the receiver object (this) with the argument object (that) for equivalence.

Any implementation of this method should be an equivalence relation:

  • It is reflexive: for any instance x of type Any, x.equals(x) should return true.
  • It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
  • It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).

Attributes

that

the object to compare against this object for equality.

Returns:

true if the receiver object is equivalent to the argument; false otherwise.

def getValue(r: ResultSet, idx: Int): T

Get a result column of the type. For reference types, SQL NULL values are returned as null, for primitive types a default value is returned.

def hasLiteralForm: Boolean

Indicates whether values of this type have a literal representation in SQL statements. This must return false if valueToSQLLiteral throws a SlickException. QueryBuilder (and profile-specific subclasses thereof) uses this method to treat LiteralNodes as volatile (i.e. using bind variables) as needed.

override def hashCode: Int

Calculate a hash code value for the object.

Calculate a hash code value for the object.

The default hashing algorithm is platform dependent.

Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.

Attributes

Returns:

the hash code value for this object.
