Property

io.getquill.ast.Property
See theProperty companion object
final class Property(val ast: Ast, val name: String)(val renameable: Renameable, val visibility: Visibility) extends Ast

Properties generally represent column selection from a table or invocation of some kind of method from some other object. Typically, something like

`SELECT p.name FROM People p`

comes from something like

`Map(Entity("People"), Ident("p"), Property(Ident(p), "name"))`

Properties also have an Opinion about how the NamingStrategy affects their name. For example something like Property.Opinionated(Ident(p), "s_name", Fixed) will become p.s_name even if the NamingStrategy is UpperCase (whereas Property(Ident(p), "s_name") would become p.S_NAME). When Property is constructed without Opinionated being used, the default opinion ByStrategy is used.

def bestQuat: Quat
def copy(ast: Ast, name: String): Property
def copyAll(ast: Ast, name: String, renameable: Renameable, visibility: Visibility): Property
override def equals(that: 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)).

Value parameters

that

the object to compare against this object for equality.

Attributes

Returns

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

Definition Classes
Any
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.
