Web API Complex and Enumeration types

Within the CSDL $metadata document, there are ComplexType and EnumType elements.

Complex types

Complex types are keyless named structured types consisting of a set of properties. Complex types are commonly used as property values in table definitions, or as parameters or return values for operations.

For example, the WhoAmI function returns this WhoAmIResponse complex type:

<ComplexType Name="WhoAmIResponse">  
  <Property Name="BusinessUnitId" Type="Edm.Guid" Nullable="false" />  
  <Property Name="UserId" Type="Edm.Guid" Nullable="false" />  
  <Property Name="OrganizationId" Type="Edm.Guid" Nullable="false" />  
</ComplexType>

Enumeration types

Enumeration types are named primitive types whose values are named constants with underlying integer values.

For example, the following XML node is the definition of the AccessRights enum type

<EnumType Name="AccessRights">  
  <Member Name="None" Value="0" />  
  <Member Name="ReadAccess" Value="1" />  
  <Member Name="WriteAccess" Value="2" />  
  <Member Name="AppendAccess" Value="4" />  
  <Member Name="AppendToAccess" Value="16" />  
  <Member Name="CreateAccess" Value="32" />  
  <Member Name="DeleteAccess" Value="65536" />  
  <Member Name="ShareAccess" Value="262144" />  
  <Member Name="AssignAccess" Value="524288" />  
</EnumType>

The AccessRights enum type is used for the AccessMask property of the PrincipalAccess complex type, which is used to set the PrincipalAccess parameter for the ModifyAccess action. Use this action to change the access when sharing a record.

The example below grants ReadAccess, WriteAccess, DeleteAccess, AppendAccess, and AssignAccess access rights to the account record specified by the Target parameter to the systemuser designated by the Principal property of the PrincipalAccess complex type.
