EdmEntityContainer

Definition

Assembly: Microsoft.OData.Mcp.Core.dll Namespace: Microsoft.OData.Mcp.Core.Models Inheritance: System.Object

Syntax

Microsoft.OData.Mcp.Core.Models.EdmEntityContainer

Summary

Represents an entity container in an OData model.

Remarks

An entity container defines the scope of addressable resources in an OData service. It contains entity sets, singletons, function imports, and action imports that comprise the service’s interface. Each OData service must have exactly one entity container.

Constructors

.ctor

Initializes a new instance of the EdmEntityContainer class.

Syntax

public EdmEntityContainer()

.ctor

Initializes a new instance of the EdmEntityContainer class with the specified name and namespace.

Syntax

public EdmEntityContainer(string name, string namespace)

Parameters

Name	Type	Description
`name`	`string`	The name of the entity container.
`namespace`	`string`	The namespace of the entity container.

Exceptions

Exception	Description
`ArgumentException`	Thrown when name or namespace is null or whitespace.

.ctor Inherited

Inherited from object

Syntax

public Object()

Properties

ActionImports

Gets or sets the action imports in this container.

Syntax

public System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmActionImport> ActionImports { get; set; }

Property Value

Type: System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmActionImport> A collection of action imports that expose actions as addressable resources.

Remarks

Action imports allow actions to be called as part of the OData service interface. Unlike functions, actions can have side effects and are typically invoked via POST requests.

Annotations

Gets or sets the annotations for this entity container.

Syntax

public System.Collections.Generic.Dictionary<string, object> Annotations { get; set; }

Property Value

Type: System.Collections.Generic.Dictionary<string, object> A dictionary of annotations that provide additional metadata about the entity container.

Remarks

Annotations can be used to specify additional behaviors, constraints, or metadata that are not captured by the standard OData model elements.

EntitySets

Gets or sets the entity sets in this container.

Syntax

public System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> EntitySets { get; set; }

Property Value

Type: System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmEntitySet> A collection of entity sets that define the collections of entities available in the service.

Remarks

Entity sets are the primary addressable resources in an OData service, allowing clients to query, create, update, and delete entities.

Extends

Gets or sets the base entity container.

Syntax

public string Extends { get; set; }

Property Value

Type: string? The fully qualified name of the base entity container, or null if this container has no base.

Remarks

When specified, this entity container extends the base container, inheriting all its entity sets, singletons, and operations. This allows for modular composition of services.

FullName

Gets the fully qualified name of the entity container.

Syntax

public string FullName { get; }

Property Value

Type: string The namespace and name combined with a dot separator.

FunctionImports

Gets or sets the function imports in this container.

Syntax

public System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmFunctionImport> FunctionImports { get; set; }

Property Value

Type: System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmFunctionImport> A collection of function imports that expose functions as addressable resources.

Remarks

Function imports allow functions to be called as part of the OData service interface. They provide a way to expose custom operations that don’t fit the standard CRUD pattern.

HasActionImports

Gets a value indicating whether this entity container has any action imports.

Syntax

public bool HasActionImports { get; }

Property Value

Type: bool true if the entity container has action imports; otherwise, false.

HasBaseContainer

Gets a value indicating whether this entity container extends another container.

Syntax

public bool HasBaseContainer { get; }

Property Value

Type: bool true if the entity container has a base container; otherwise, false.

HasEntitySets

Gets a value indicating whether this entity container has any entity sets.

Syntax

public bool HasEntitySets { get; }

Property Value

Type: bool true if the entity container has entity sets; otherwise, false.

HasFunctionImports

Gets a value indicating whether this entity container has any function imports.

Syntax

public bool HasFunctionImports { get; }

Property Value

Type: bool true if the entity container has function imports; otherwise, false.

HasSingletons

Gets a value indicating whether this entity container has any singletons.

Syntax

public bool HasSingletons { get; }

Property Value

Type: bool true if the entity container has singletons; otherwise, false.

Name

Gets or sets the name of the entity container.

Syntax

public required string Name { get; set; }

Property Value

Type: string The local name of the entity container within its namespace.

Namespace

Gets or sets the namespace of the entity container.

Syntax

public required string Namespace { get; set; }

Property Value

Type: string The namespace that contains this entity container.

Singletons

Gets or sets the singletons in this container.

Syntax

public System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmSingleton> Singletons { get; set; }

Property Value

Type: System.Collections.Generic.List<Microsoft.OData.Mcp.Core.Models.EdmSingleton> A collection of singletons that define individual entity resources.

Remarks

Singletons represent entities that exist as single instances rather than collections. They are useful for representing unique resources like service configuration or user profiles.
