Detailed Description

Realm configuration specifying settings that affect your Realm behaviour.

Main role is generating a canonical path from whatever absolute, relative subdir or just filename user supplies.

Constructor & Destructor Documentation

RealmConfiguration	(	string	optionalPath = null,
		bool	shouldDeleteIfMigrationNeeded = false
	)

Constructor allowing path override.

Parameters

optionalPath	Path to the realm, must be a valid full path for the current platform, relative subdir, or just filename.
shouldDeleteIfMigrationNeeded	Optional Flag mainly to help with temp databases and testing, indicates content can be abandoned when you change the schema.

Member Function Documentation

RealmConfiguration ConfigWithPath

(

string

newConfigPath

)

Clone method allowing you to override or customise the current path.

Returns

An object with a fully-specified, canonical path.

Parameters

newConfigPath

Path to the realm, must be a valid full path for the current platform, relative subdir, or just filename.

override bool Equals

(

Object

rhs

)

Generic override determines whether the specified System.Object is equal to the current RealmConfiguration.

Parameters

rhs	The System.Object to compare with the current RealmConfiguration.

Returns

true if the specified System.Object is equal to the current Realms.RealmConfiguration; otherwise, false.

Referenced by Realm.Equals().

bool Equals

(

RealmConfiguration

rhs

)

Determines whether the specified RealmConfiguration is equal to the current RealmConfiguration.

Parameters

rhs	The System.Object to compare with the current RealmConfiguration.

Returns

true if the specified System.Object is equal to the current Realms.RealmConfiguration; otherwise, false.

override int GetHashCode

(

)

Serves as a hash function for a RealmConfiguration based on its path.

Returns

A hash code for this instance that is suitable for use in hashing algorithms and data structures such as a hash table.

static string PathToRealm ( string  optionalPath = null )

static

Utility to build a path in which a realm will be created so can consistently use filenames and relative paths.

References RealmConfiguration.DefaultRealmName.

Referenced by RealmConfiguration.RealmConfiguration().

Member Data Documentation

string DefaultRealmName => "default.realm"

static

Standard filename to be combined with the platform-specific document directory.

A string representing a filename only, no path.

Referenced by RealmConfiguration.PathToRealm().

UInt64 NotVersioned => UInt64.MaxValue

static

Constant used for SchemaVersion to indicate is not versioned.

Must be maintained to match an internal ObjectStore::NotVersioned.

Maximum value of UInt64.

bool ReadOnly

Flag to indicate Realm is opened readonly so can open from locked locations such as bundled with an application.

Referenced by Realm.GetInstance().

readonly bool ShouldDeleteIfMigrationNeeded

Flag mainly to help with temp databases and testing, indicates content can be abandoned when you change the schema.

Referenced by RealmConfiguration.Equals(), and Realm.GetInstance().

Property Documentation

string DatabasePath

get

The full path of any realms opened with this configuration, may be overriden by passing in a separate name.

Referenced by RealmConfiguration.ConfigWithPath(), Realm.DeleteRealm(), RealmConfiguration.Equals(), RealmConfiguration.GetHashCode(), Realm.GetInstance(), and RealmConfiguration.RealmConfiguration().

RealmConfiguration DefaultConfiguration

staticgetset

Configuration you can override which is used when you create a new Realm without specifying a configuration.

Referenced by Realm.GetInstance().

byte [] EncryptionKey

getset

Specify the key used to encrypt the entire Realm. Once set, must be specified each time file is used.

Full 64byte (512bit) key for AES-256 encryption.

Referenced by RealmConfiguration.Equals(), and Realm.GetInstance().

Type [] ObjectClasses

getset

The list of classes persisted in a Realm opened with this configuration.

Specify classes by type. Searched linearly so order in decreasing frequency of creating objects.

eg: config.ObjectClasses = new Type[] { typeof(CommonClass), typeof(RareClass) };

Typically left null so by default all RealmObjects will be able to be stored in all realms.

Referenced by Realm.GetInstance().

UInt64 SchemaVersion

getset

Number indicating the version, can be used to arbitrarily distinguish between schemas even if they have the same objects and properties.

0-based value initially set to indicate user is not versioning.
