Visual Studio Template Reference Template Parameters. Template parameter deduction from array. The template facility in C++ doesn't only allow you to parameterise with types (such as the int in std: :vector< int> ), but also with values. Non- type template parameters can be of the following types. The standard states that a value of type . ISO C++ standard 1. C++1. 1 has a few additions. Stroustrup - The C++ Programming Language, Special Edition; Appendix C.
Deducing Function Template Arguments. ISO C++ standard 1. Initializes a new instance of the UriTemplate class with the specified template string. Resource Manager Template Functions . For example, Resource Manager resolves variables('var. VARIABLES('VAR1') as the same. When evaluated, unless the function expressly modifies case (such as to. Upper or to. Lower), the function preserves the case. Certain resource types may have case requirements irrespective of how functions are evaluated. Numeric functions. Resource Manager provides the following functions for working with integers: addadd(operand. Returns the sum of the two provided integers. Parameter. Required. Descriptionoperand. Yes. First integer to add. Yes. Second integer to add. The following example adds two parameters. Parameter. Required. Descriptionoffset. Template Parameter Type To String C#No. The amount to add to current iteration value. This function is always used with a copy object. For a complete description of how you use copy. Index, see Create multiple instances of resources in Azure Resource Manager. The following example shows a copy loop and the index value included in the name. Cannot be 0. The following example divides one parameter by another parameter. The type of value can only be String or Integer. The following example converts the user- provided parameter value to Integer. Parameter. Required. Descriptionstring. Yes. A string value to concatenate. No. String values to concatenate. This function can take any number of arguments, and can accept either strings or arrays for the parameters. For an example of concatenating arrays, see concat - array. The following example shows how to combine multiple string values to return a concatenated string. The default value is a space. The following example shows how to pad the user- provided parameter value by adding the zero character until the string reaches 1. If the original parameter value is longer than 1. If this value is 0 or less, all the characters in the string are returned. If it is larger than the length of the string, an empty string is returned. For an example of using skip with an array, see skip - array. The following example skips the specified number of characters in the string. Any type of value can be converted, including objects and arrays. The following example converts the user- provided parameter values to strings. If this value is 0 or less, an empty string is returned. If it is larger than the length of the given string, all the characters in the string are returned. For an example of using take with an array, see take - array. The following example takes the specified number of characters from the string. Parameter. Required. Descriptionbase. String. Yes. The string used in the hash function to create a unique string. No. You can add as many strings as needed to create the value that specifies the level of uniqueness. This function is helpful when you need to create a unique name for a resource. You provide parameter values that limit the scope of uniqueness for the result. You can specify whether the name is unique down to subscription, resource group, or deployment. The returned value is not a random string, but rather the result of a hash function. The returned value is 1. It is not globally unique. You may want to combine the value with a prefix from your naming convention to create a name that is meaningful. The following example shows the format of the returned value. Of course, the actual value will vary by the provided parameters. The following examples show how to use unique. String to create a unique value for commonly used levels. Unique scoped to subscription. For example, passing http: //contoso. Uri parameter results in a base URI of http: //contoso. The following example shows how to construct a link to a nested template based on the value of the parent template. Parameter. Required. Descriptionarray. Yes. An array to concatenate. No. Arrays to concatenate. This function can take any number of arguments, and can accept either strings or arrays for the parameters. For an example of concatenating string values, see concat - string. The following example shows how to combine two arrays. In the following example, the parameter site. Names would refer to an array of names to use when creating the web sites. For an example of using length with a string value, see length - string. Value, number. To. Skip)Returns an array with all the elements after the specified number in the array. Parameter. Required. Descriptionoriginal. Value. Yes. The array to use for skipping. To. Skip. Yes. The number of elements to skip. If this value is 0 or less, all the elements in the array are returned. If it is larger than the length of the array, an empty array is returned. For an example of using skip with a string, see skip - string. The following example skips the specified number of elements in the array. If this value is 0 or less, an empty array is returned. If it is larger than the length of the given array, all the elements in the array are returned. For an example of using take with a string, see take - string. The following example takes the specified number of elements from the array. The properties in the returned object differ based on whether the deployment object is passed as a link or as an in- line object. When the deployment object is passed in- line, such as when using the - Template. File parameter in Azure Power. Shell to point to a local file, the returned object has the following format. The specified parameter name must be defined in the parameters section of the template. Parameter. Required. Descriptionparameter. Name. Yes. The name of the parameter to return. The following example shows a simplified use of the parameters function. The specified variable name must be defined in the variables section of the template. Parameter. Required. Descriptionvariable Name. Yes. The name of the variable to return. The following example uses a variable value. The most common usage is list. Keys. Parameter. Required. Descriptionresource. Name or resource. Identifier. Yes. Unique identifier for the resource. Version. Yes. API version of resource runtime state. Any operation that starts with list can be used a function in your template. The available operations include not only list. Keys, but also operations like list, list. Admin. Keys, and list. Status. To determine which resource types have a list operation, use the following Power. Shell command. Get- Azure. Rm. Provider. Operation - Operation. Search. String * . The following example retrieves all the operations for apiapps, and uses the JSON utility jq to filter only the list operations. Search. String */apiapps/* - -json . If you do not provide a resource type, the function returns all the supported types for the resource provider. Parameter. Required. Descriptionprovider. Namespace. Yes. Namespace of the providerresource. Type. No. The type of resource within the specified namespace. Each supported type is returned in the following format. Array ordering is not guaranteed. Include this parameter when the resource is not provisioned within same template. The reference function derives its value from a runtime state, and therefore cannot be used in the variables section. It can be used in outputs section of a template. By using the reference function, you implicitly declare that one resource depends on another resource if the referenced resource is provisioned within same template. You do not need to also use the depends. On property. The function is not evaluated until the referenced resource has completed deployment. The following example references a storage account that is deployed in the same template. To see the property names and values for a resource type, create a simple template that returns the object in the outputs section. If you have an existing resource of that type, your template just returns the object without deploying any new resources. If you do not have an existing resource of that type, your template deploys only that type and returns the object. Then, add those properties to other templates that need to dynamically retrieve the values during deployment. The returned object is in the following format. Parameter. Required. Descriptionsubscription. Id. No. Default value is the current subscription. Specify this value when you need to retrieve a resource in another subscription. Group. Name. No. Default value is current resource group. Specify this value when you need to retrieve a resource in another resource group. Type. Yes. Type of resource including resource provider namespace. Name. 1Yes. Name of resource. Name. 2No. Next resource name segment if resource is nested. You use this function when the resource name is ambiguous or not provisioned within the same template. The identifier is returned in the following format: /subscriptions/. The web site exists in a resource group named my. Websites. Group and the database exists in the current resource group for this template. The storage account or virtual network may be used across multiple resource groups; therefore, you do not want to delete them when deleting a single resource group. The following example shows how a resource from an external resource group can easily be used.
