Summary Represents an entity container in an OData model.
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 Initializes a new instance of the EdmEntityContainer class.
Syntax public EdmEntityContainer ()
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 namestringThe name of the entity container. namespacestringThe namespace of the entity container.
Exceptions Exception Description ArgumentExceptionThrown when name or namespace is null or whitespace.
Inherited Syntax Properties 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.
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.
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.
Annotations can be used to specify additional behaviors, constraints, or metadata
that are not captured by the standard OData model elements.
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.
Entity sets are the primary addressable resources in an OData service, allowing clients
to query, create, update, and delete entities.
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.
When specified, this entity container extends the base container, inheriting all its
entity sets, singletons, and operations. This allows for modular composition of services.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Singletons represent entities that exist as single instances rather than collections.
They are useful for representing unique resources like service configuration or user profiles.
Methods Adds an annotation to this entity container.
Syntax public void AddAnnotation ( string term , object value )
Parameters Name Type Description termstringThe annotation term. valueobjectThe annotation value.
Exceptions Exception Description ArgumentExceptionThrown when term is null or whitespace.
Adds an entity set to this container.
Syntax public void AddEntitySet ( Microsoft . OData . Mcp . Core . Models . EdmEntitySet entitySet )
Parameters Name Type Description entitySetMicrosoft.OData.Mcp.Core.Models.EdmEntitySetThe entity set to add.
Exceptions Exception Description ArgumentNullExceptionThrown when entitySet is null. InvalidOperationExceptionThrown when an entity set with the same name already exists.
Adds a singleton to this container.
Syntax public void AddSingleton ( Microsoft . OData . Mcp . Core . Models . EdmSingleton singleton )
Parameters Name Type Description singletonMicrosoft.OData.Mcp.Core.Models.EdmSingletonThe singleton to add.
Exceptions Exception Description ArgumentNullExceptionThrown when singleton is null. InvalidOperationExceptionThrown when a singleton with the same name already exists.
