NumericString

org.scalactic.anyvals.NumericString
See theNumericString companion object
final class NumericString extends AnyVal

An AnyVal for numeric Strings.

Note: a NumericString contains only numeric digit characters.

Because NumericString is an AnyVal it will usually be as efficient as a String, being boxed only when a String would have been boxed.

The NumericString.apply factory method is implemented in terms of a macro that checks literals for validity at compile time. Calling NumericString.apply with a literal String value will either produce a valid NumericString instance at run time or an error at compile time. Here's an example:

scala> import anyvals._
import anyvals._

scala> NumericString("42")
res0: org.scalactic.anyvals.NumericString = NumericString(42)

scala> NumericString("abc")
<console>:11: error: NumericString.apply can only be invoked on String literals that contain numeric characters, i.e., decimal digits '0' through '9', like "123".
             NumericString("abc")
                          ^

NumericString.apply cannot be used if the value being passed is a variable (i.e., not a literal), because the macro cannot determine the validity of variables at compile time (just literals). If you try to pass a variable to NumericString.apply, you'll get a compiler error that suggests you use a different factory method, NumericString.from, instead:

scala> val x = "1"
x: String = 1

scala> NumericString(x)
<console>:15: error: NumericString.apply can only be invoked on String literals that contain only numeric characters, i.e., decimal digits '0' through '9', like "123" Please use NumericString.from instead.
             NumericString(x)
                          ^

The NumericString.from factory method will inspect the value at runtime and return an Option[NumericString]. If the value is valid, NumericString.from will return a Some[NumericString], else it will return a None. Here's an example:

scala> NumericString.from(x)
res3: Option[org.scalactic.anyvals.NumericString] = Some(NumericString(1))

scala> val y = "a"
y: String = a

scala> NumericString.from(y)
res4: Option[org.scalactic.anyvals.NumericString] = None

def aggregate[B](z: => B)(seqop: (B, Char) => B, combop: (B, B) => B): B

Aggregates the results of applying an operator to subsequent elements of this NumericString.

Aggregates the results of applying an operator to subsequent elements of this NumericString.

This is a more general form of fold and reduce. It is similar to foldLeft in that it doesn't require the result to be a supertype of the element type.

aggregate splits the elements of this NumericString into partitions and processes each partition by sequentially applying seqop, starting with z (like foldLeft). Those intermediate results are then combined by using combop (like fold). The implementation of this operation may operate on an arbitrary number of collection partitions (even 1), so combop may be invoked an arbitrary number of times (even 0).

As an example, consider summing up the integer values the character elements. The initial value for the sum is 0. First, seqop transforms each input character to an Int and adds it to the sum (of the partition). Then, combop just needs to sum up the intermediate results of the partitions:

  NumericString("123").aggregate(0)({ (sum, ch) => sum + ch.toInt }, { (p1, p2) => p1 + p2 })

Value parameters

B

the type of accumulated results

combop

an associative operator used to combine results within a partition

seqop

an operator used to accumulate results within a partition

z

the initial value for the accumulated result of the partition - this will typically be the neutral element for the seqop operator (e.g. Nil for list concatenation or 0 for summation) and may be evaluated more than once

def ensuringValid(f: String => String): NumericString

Applies the passed String => String function to the underlying String value, and if the result is a numeric string, returns the result wrapped in a NumericString, else throws AssertionError.

Applies the passed String => String function to the underlying String value, and if the result is a numeric string, returns the result wrapped in a NumericString, else throws AssertionError.

A factory/assertion method that produces a NumericString given a valid String value, or throws AssertionError, if given an invalid String value.

Note: you should use this method only when you are convinced that it will always succeed, i.e., never throw an exception. It is good practice to add a comment near the invocation of this method indicating ''why'' you think it will always succeed to document your reasoning. If you are not sure an ensuringValid call will always succeed, you should use one of the other factory or validation methods provided on this object instead: isValid, tryingValid, passOrElse, goodOrElse, or rightOrElse.

This method will inspect the result of applying the given function to this NumericString's underlying String value and if the result is a valid numeric string, it will return a NumericString representing that value. Otherwise, the String value returned by the given function is not a valid numeric string, so this method will throw AssertionError.

This method differs from a vanilla assert or ensuring call in that you get something you didn't already have if the assertion succeeds: a type that promises a String contains only numeric digit characters. With this method, you are asserting that you are convinced the result of the computation represented by applying the given function to this NumericString's value will produce a valid numeric string. Instead of producing an invalid NumericString, this method will signal an invalid result with a loud AssertionError.

Value parameters

f

the String => String function to apply to this NumericString's underlying String value.

Attributes

Returns

the result of applying this NumericString's underlying String value to to the passed function, wrapped in a NumericString if it is a valid numeric string (else throws AssertionError).

Throws
AssertionError

if the result of applying this NumericString's underlying String value to to the passed function contains non-digit characters.
