Error {errorId}: The file {filename} could not be read.
When the error occurs, the message could be prepared for display with the following code:
var template:String = "Error {errorId}: The file {filename} could not be read.";
var params:Object = new Object();
params.errorId = 42;
params.filename = "/Users/alice/vacation.jpg";
var message:String = FormatMessage.formatString(template, params);
// message="Error 42: The file /Users/alice/vacation.jpg could not be read."
The ActionScript object literal syntax is a convenient way to construct the parameter object. The following is functionally equivalent to the code above:
var template:String = "Error {errorId}: The file {filename} could not be read.";
var params:Object =
{
errorId: 42,
filename: "/Users/alice/vacation.jpg"
};
var message:String = FormatMessage.formatString(template, params);
// message="Error 42: The file /Users/alice/vacation.jpg could not be read."
Note that traditional numeric parameters are supported by simply using an Array as the parameter object:
var template:String = "Error {0}: The file {1} could not be read.";
var params:Array =
[
42,
"/Users/alice/vacation.jpg"
];
var message:String = FormatMessage.formatString(template, params);
// message="Error 42: The file /Users/alice/vacation.jpg could not be read."
Note that for missing parameters, the empty string will be used:
var template:String = "Error {errorId}: The file {filename} could not be read.";
var params:Object =
{
errorId: 42,
};
var message:String = FormatMessage.formatString(template, params);
// message="Error 42: The file could not be read."
Note that parameters are substituted verbatim, no parameter replacement or brace processing is performed on the parameters themselves:
var template:String = "{one}{two}{three}{four}{five}";
var params:Object =
{
one: "{five}",
two: "{four}",
three: "{three}",
four: "{two}",
five: "{one}"
};
var message:String = FormatMessage.formatString(template, params);
// message="{five}{four}{three}{two}{one}"
To escape an opening brace, double the initial brace:
var template:String = "The {{filename} parameter is {filename}.";
var message:String = FormatMessage.formatString(template, {filename: "/Users/alice/vacation.jpg"});
// message="The {filename} parameter is /Users/alice/vacation.jpg."
Best practice: It can be useful to use formatString on all strings, parameterized or not, to ensure that escaping rules are consistent between parameterized and non-parameterized strings (since strings that were unparameterized may become parameterized and vice-versa).

Given a message string, perform parameter substitution on it.
Paramètres
message:String — The parameterized message string. Must not be null.
| |
parameters:Object — An object with a property for each parameter that is to be substituted into the message. May be null (which means there are no parameters to be substituted).
|
String — The message string with any parameter substitution performed.
