Enumeration 列挙

AttributedString.AttributeMergePolicy

An enumeration of behaviors to apply when merging attributes.

Declaration 宣言 

enum AttributedString.AttributeMergePolicy

Overview 概要

Use an AttributedString.AttributeMergePolicy when working with methods like mergeAttributes(_:mergePolicy:) to indicate how to resolve conflicts between multiple sets of attributes. When a source string and a merging attribute container both contain a given attribute with different values, the merge policy determines how to resolve the conflict.

Merge Policies

case keepCurrent
A policy to keep the string’s current attribute value when merging multiple sets of attributes.
case keepNew
A policy to keep the newly-merged attribute value when merging multiple sets of attributes.

Hashing ハッシュ化

var hashValue: Int
The hash value. ハッシュ値。
func hash(into: inout Hasher)
Hashes the essential components of this value by feeding them into the given hasher. この値の本質的な構成要素それらを、それらをこの与えられたハーシャーに供給する事によってハッシュ化します。

Comparing Merge Policies

static func == (AttributedString.AttributeMergePolicy, AttributedString.AttributeMergePolicy) -> Bool
Returns a Boolean value that indicates whether two merge policies are equal.
static func != (AttributedString.AttributeMergePolicy, AttributedString.AttributeMergePolicy) -> Bool
Returns a Boolean value that indicates whether two merge policies are not equal.
