Slice

dev.constructive.eo.data.PSVec.Slice
final class Slice[+B] extends PSVec[B]

Array-backed view with offset + length. slice is a pointer update over the shared backing array — the zero-copy reassembly path mfAssocPSVec depends on.

override def toAnyRefArray: Array[AnyRef]

Materialise as a fresh Array[AnyRef]. Slice overrides with System.arraycopy (intrinsic) so the common rebuild path in Traversal.pEach's from is one memcpy.

override def unsafeShareableArray: Array[AnyRef]

Like toAnyRefArray but MAY share the backing array zero-copy when a dense Slice covers its full range. Callers MUST treat the result as immutable. Used by consumers that also won't mutate, e.g. optics.Traversal.pEach's fromArraySeq.unsafeWrapArray). Default is the safe copy; only Slice overrides to share.

Inherited methods

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.

override def hashCode(): Int

Calculates a hash code value for the object.

Calculates 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.
