trait Slice[T] extends (Int) => T
Lazy and immutable slice of a sequence of values.
- T
type of the items of the sequence.
- Note
As the slice usually wraps over a mutable structure, like an array or a java buffer, and it DOES NOT make an instant copy, any changes to the underlying source will directly affect the slice output unless detached. Detach is a one-time copy operation, and
detachedproperty is preserved across all operations returning a Slice.

Abstract Value Members
- abstract def asArray: Array[T]
Returns a trimmed copy of an underlying array.
- abstract def asBuffer: Buffer[T]
Returns a buffer with a copy of this Slice.
- abstract def detach: Slice.this.type
Detaches a slice creating a trimmed copy of an underlying data, if needed.
Detaches a slice creating a trimmed copy of an underlying data, if needed. Subsequent detach operations will return the same instance without making new copies.
- abstract val length: Int
Returns length of the Slice.
- abstract def map[K](f: (T) => K): Slice[K]
Lazily composes mapping function and returns new Slice.
Lazily composes mapping function and returns new Slice. Does not modify nor copy underlying array.
- abstract def read(index: Int): T
Returns value at the given index without checks.
Returns value at the given index without checks.
- Attributes
- protected
- abstract def slice(from: Int, to: Int): Slice.this.type
Lazily narrows Slice to provided range.
- abstract def toBuffer[T1 >: T]: Buffer[T1]
Returns a buffer with a copy of this Slice.
- abstract def update[T1 >: T](index: Int, value: T1): Slice[T1]
Update a value at the given index.
Update a value at the given index. Creates a copy of an underlying data.
