// ListForResource this operation retrieves the list of all policy assignments associated with the specified resource

// 'atScope()' or 'policyDefinitionId eq '{value}''. If $filter is not provided, the unfiltered list includes all
// policy assignments associated with the resource, including those that apply directly or from all containing scopes,
// as well as any applied to resources contained within the resource. If $filter=atScope() is provided, the returned
// list includes all policy assignments that apply to the resource, which is everything in the unfiltered list except
// those applied to resources contained within the resource. If $filter=policyDefinitionId eq '{value}' is provided,
// the returned list includes only policy assignments that apply to the resource and assign the policy definition whose
// id is {value}. Three parameters plus the resource name are used to identify a specific resource. If the resource is
// not part of a parent resource (the more common case), the parent resource path should not be provided (or provided
// as ''). For example a web app could be specified as ({resourceProviderNamespace} == 'Microsoft.Web',
// {parentResourcePath} == '', {resourceType} == 'sites', {resourceName} == 'MyWebApp'). If the resource is part of a
// parent resource, then all parameters should be provided. For example a virtual machine DNS name could be specified
// as ({resourceProviderNamespace} == 'Microsoft.Compute', {parentResourcePath} == 'virtualMachines/MyVirtualMachine',
// {resourceType} == 'domainNames', {resourceName} == 'MyComputerName'). A convenient alternative to providing the
// namespace and type name separately is to provide both in the {resourceType} parameter, format:
// ({resourceProviderNamespace} == '', {parentResourcePath} == '', {resourceType} == 'Microsoft.Web/sites',
// {resourceName} == 'MyWebApp').
// Parameters:
// resourceGroupName - the name of the resource group containing the resource.
// resourceProviderNamespace - the namespace of the resource provider. For example, the namespace of a virtual
// machine is Microsoft.Compute (from Microsoft.Compute/virtualMachines)
// parentResourcePath - the parent resource path. Use empty string if there is none.
// resourceType - the resource type name. For example the type name of a web app is 'sites' (from
// Microsoft.Web/sites).
// resourceName - the name of the resource.
// filter - the filter to apply on the operation. Valid values for $filter are: 'atScope()' or
// 'policyDefinitionId eq '{value}''. If $filter is not provided, no filtering is performed.
