Class RealmSchema

Describes the complete set of classes which may be stored in a Realm, either from assembly declarations or, dynamically, by evaluating a Realm from disk. To construct a new RealmSchema instance, use the RealmSchema.Builder API.

Inheritance

Object

RealmSchema

Implements

IReadOnlyCollection<ObjectSchema>

IEnumerable<ObjectSchema>

IEnumerable

Namespace: Realms.Schema

Assembly: Realm.dll

Syntax

public class RealmSchema : IReadOnlyCollection<ObjectSchema>, IEnumerable<ObjectSchema>, IEnumerable

Remarks

By default this will be all the RealmObjects, EmbeddedObjects and AsymmetricObjects in all your assemblies. Unless you restrict with Schema. Just because a given class may be stored in a Realm doesn't imply much overhead. There will be a small amount of metadata but objects only start to take up space once written.

Properties

Count

Gets the number of known classes in the schema.

Declaration

public int Count { get; }

Property Value

Type	Description
Int32	The number of known classes.

Methods

AddDefaultTypes(IEnumerable<Type>)

Adds a collection of types to the default schema.

Declaration

public static void AddDefaultTypes(IEnumerable<Type> types)

Parameters

Type	Name	Description
IEnumerable<Type>	types	Types to be added to the default schema.

Exceptions

Type	Condition
NotSupportedException	Thrown if the schema has already materialized.

Find(String)

Finds the definition of a class in this schema.

Declaration

[Obsolete("This method is obsolete. Use TryFindObjectSchema instead.")]
public ObjectSchema Find(string name)

Parameters

Type	Name	Description
String	name	A valid class name which may be in this schema.

Returns

Type	Description
ObjectSchema	An ObjectSchema or null to indicate not found.

Exceptions

Type	Condition
ArgumentException	Thrown if a name is not supplied.

GetBuilder()

Create a mutable RealmSchema.Builder containing the object schemas in this Realm schema.

Declaration

public RealmSchema.Builder GetBuilder()

Returns

Type	Description
RealmSchema.Builder	A RealmSchema.Builder instance that can be used to mutate the schema and eventually produce a new one by calling Build().

TryFindObjectSchema(String, out ObjectSchema)

Attempts to find the definition of a class in this schema.

Declaration

public bool TryFindObjectSchema(string name, out ObjectSchema schema)

Parameters

Type	Name	Description
String	name	A valid class name which may be in this schema.
ObjectSchema	schema	The schema corresponding to the provided name or null if the schema is not found.

Returns

Type	Description
Boolean	true if this RealmSchema contains a class definition with the supplied name; false otherwise.

Exceptions

Type	Condition
ArgumentException	Thrown if a name is not supplied.

Operators

Implicit(ObjectSchema[] to RealmSchema)

Constructs a RealmSchema from an array of ObjectSchema instances.

Declaration

public static implicit operator RealmSchema(ObjectSchema[] objects)

Parameters

Type	Name	Description
ObjectSchema[]	objects	The object schemas that will be contained in the newly constructed RealmSchema.

Returns

Type	Description
RealmSchema	null if objects is null; a RealmSchema containing the supplied ObjectSchemas otherwise.

Exceptions

Type	Condition
ArgumentException	Thrown if the array contains multiple ObjectSchema instances with the same Name.

Implicit(RealmSchema.Builder to RealmSchema)

A convenience operator to construct a RealmSchema from a RealmSchema.Builder by calling the Build() method.

Declaration

public static implicit operator RealmSchema(RealmSchema.Builder builder)

Parameters

Type	Name	Description
RealmSchema.Builder	builder	The builder that describes the newly created schema.

Returns

Type	Description
RealmSchema	null if builder is null; the result of Build() otherwise.

Implicit(HashSet<Type> to RealmSchema)

Constructs a RealmSchema from a HashSet of Type instances.

Declaration

public static implicit operator RealmSchema(HashSet<Type> objects)

Parameters

Type	Name	Description
HashSet<Type>	objects	The Types that will be converted to ObjectSchema and added to the resulting RealmSchema.

Returns

Type	Description
RealmSchema	null if objects is null; a RealmSchema containing the supplied ObjectSchemas otherwise.

Add(Type)

Implicit(List<ObjectSchema> to RealmSchema)

Constructs a RealmSchema from a list of ObjectSchema instances.

Declaration

public static implicit operator RealmSchema(List<ObjectSchema> objects)

Parameters

Type	Name	Description
List<ObjectSchema>	objects	The object schemas that will be contained in the newly constructed RealmSchema.

Returns

Type	Description
RealmSchema	null if objects is null; a RealmSchema containing the supplied ObjectSchemas otherwise.

Exceptions

Type	Condition
ArgumentException	Thrown if the list contains multiple ObjectSchema instances with the same Name.

Constructs a RealmSchema from a List of Type instances.

Declaration

Parameters

Type	Name	Description
List<Type>	objects	The Types that will be converted to ObjectSchema and added to the resulting RealmSchema.

Returns

Type	Description
RealmSchema	null if objects is null; a RealmSchema containing the supplied ObjectSchemas otherwise.

Declaration

Parameters

Type	Name	Description
Type[]	objects	The Types that will be converted to ObjectSchema and added to the resulting RealmSchema.
