Reader

Abstract Value Members

abstract def canRead(value: BValue): Boolean

Checks if this reader can handle the provided value.
Checks if this reader can handle the provided value.
value
a backend value
returns
true if this reader can read from value, false otherwise
abstract def read(value: BValue): T

Deserializes the value of the specified type from the provided backend value.
Deserializes the value of the specified type from the provided backend value.
This method should fail with an exception if canRead returns false on this value and it returns a deserialized object successfully otherwise.
value
a backend value
returns
deserialized variant of value

final def andThen[U](f: (T) ⇒ U): (TypesComponent.this)#Reader[U]

f

final def orElse(other: (TypesComponent.this)#PF[BValue, T]): (TypesComponent.this)#Reader[T]

A shorthand for this.orElse(Reader(other)), where other is a partial function.
A shorthand for this.orElse(Reader(other)), where other is a partial function. See Reader.apply.
other
a partial function which is used to create the fallback reader
returns
see another orElse method
final def orElse(other: (TypesComponent.this)#Reader[T]): (TypesComponent.this)#Reader[T]

Combines this reader with the specified fallback reader which is used if this reader can't handle the provided value based on its canRead result.
Combines this reader with the specified fallback reader which is used if this reader can't handle the provided value based on its canRead result.
other
the fallback reader
returns
a reader which delegates to this reader if this reader can deserialize a value or to the other reader otherwise
def readOrElse(value: BValue, fallback: (BValue) ⇒ T): T

Deserializes the value of the specified type from the provided backend value or applies the given function if it is impossible.
Deserializes the value of the specified type from the provided backend value or applies the given function if it is impossible.
This method is equivalent to if (this.canRead(value)) this.read(value) else fallback(value) (which is in fact its default implementation) but it can be overridden to avoid excessive checks. See PartialFunction.applyOrElse method for longer explanation.
Reader.apply and Reader.reading method overrides this method to employ the provided partial function applyOrElse method. Consider implementing this method for your readers if for some reason you don't use Reader.apply or Reader.reading.
