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 detached property is preserved across all operations returning a Slice.

Abstract Value Members

  1. abstract def asArray: Array[T]

    Returns a trimmed copy of an underlying array.

  2. abstract def asBuffer: Buffer[T]

    Returns a buffer with a copy of this Slice.

  3. 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.

  4. abstract val length: Int

    Returns length of the Slice.

  5. 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.

  6. abstract def read(index: Int): T

    Returns value at the given index without checks.

    Returns value at the given index without checks.

  7. abstract def slice(from: Int, to: Int): Slice.this.type

    Lazily narrows Slice to provided range.

  8. abstract def toBuffer[T1 >: T]: Buffer[T1]

    Returns a buffer with a copy of this Slice.

  9. 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.
