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

​
Syntax

Microsoft.OData.Mcp.Core.Models.EdmFunctionImport

​
Summary

Represents a function import in an OData entity container.

​
Remarks

Function imports expose functions as addressable resources in the OData service. They allow functions to be called through the service interface, providing custom operations that don’t fit the standard CRUD pattern. Functions are side-effect free and can be invoked using GET requests.

​
Constructors

​
.ctor

Initializes a new instance of the EdmFunctionImport class.

​
Syntax

public EdmFunctionImport()

​
.ctor

Initializes a new instance of the EdmFunctionImport class with the specified name and function.

​
Syntax

public EdmFunctionImport(string name, string function)

​
Parameters

NameTypeDescription
namestringThe name of the function import.
functionstringThe fully qualified name of the function being imported.

​
Exceptions

ExceptionDescription
ArgumentExceptionThrown when name or function is null or whitespace.

​
.ctor Inherited

Inherited from object

​
Syntax

public Object()

​
Properties

​
Annotations

Gets or sets the annotations for this function import.

​
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 function import.

​
Remarks

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

​
EntitySet

Gets or sets the entity set associated with this function import.

​
Syntax

public string EntitySet { get; set; }

​
Property Value

Type: string? The name of the entity set, or null if the function doesn’t return entities from a specific set.

​
Remarks

When the function returns entities, this property specifies which entity set those entities belong to. This is important for establishing the correct context for navigation properties and other operations.

​
Function

Gets or sets the fully qualified name of the function being imported.

​
Syntax

public required string Function { get; set; }

​
Property Value

Type: string The namespace and name of the function that this import exposes.

​
Remarks

This references a function defined elsewhere in the model. The function import makes the function accessible as part of the entity container’s interface.

​
IncludeInServiceDocument

Gets or sets a value indicating whether this function import is included in the service document.

​
Syntax

public bool IncludeInServiceDocument { get; set; }

​
Property Value

Type: bool true if the function import should be included in the service document; otherwise, false.

​
Remarks

When true, the function import will be listed in the service document, making it discoverable by clients. When false, clients must know the function import name in advance to use it.

​
Name

Gets or sets the name of the function import.

​
Syntax

public required string Name { get; set; }

​
Property Value

Type: string The name used to address this function import in OData URLs.

​
Remarks

The function import name appears in the URL path when invoking the function.

​
Methods

​
AddAnnotation

​
Syntax

​
Parameters
