## Overview

This module provides the URL encoding/decoding functions.

URL encoding stands for encoding certain characters in a URL by replacing them with one or more character triplets that consist of the percent character `%` followed by two hexadecimal digits. The two hexadecimal digits of the triplet(s) represent the numeric value of the replaced character.

The Ballerina `url` module facilitates APIs to encode and decode a URL or part of a URL.


Represents the error type of the module.


Error

Decodes the given string value into a `string` using the provided charset.
```ballerina
string value = "http://www.domain.com/?param1=http%3A%2F%2Fxyz.com%2F%3Fa%3D12%26b%3D55¶m2=99";
string decoded = check url:decode(value, "UTF-8");
```

Describes the Java class representing a Ballerina binding.
```ballerina
@java:Binding {
  'class: "java.io.File"
}
```


Describes a Java constructor, which provides an implementation of a Ballerina function of which the body is marked as
`external`. If the Ballerina function body is marked as `external`, it means that the implementation of the
function is not provided in the Ballerina source module.

The following code snippet shows an example usage of this annotation. Here, the `newJavaLinkedList` Ballerina function's
implementation is provided by the default constructor of the `java.util.LinkedList` class.
```ballerina
function newJavaLinkedList() returns handle = @java:Constructor {
     'class: "java.util.LinkedList"
} external;
```


Identifies a type, class, or function that is used in the Java native code. This annotation should be added by the
developer if the type, class, or function could be accessed via runtime APIs such as `ValueCreator`.
```ballerina
@java:ExternalDependency
function foo(int x) returns int => x * 2;
```


Describes a Java Field access, which provides an implementation of a Ballerina function of which the body is marked as
`external`.
```ballerina
function getError() returns handle = @java:FieldGet {
    name:"err",
    'class:"java/lang/System"
} external;
```


Describes a Java Field mutate, which provides an implementation of a Ballerina function of which the body is marked as
`external`.
```ballerina
function setContractId(handle contractId) = @java:FieldSet {
  name:"contractId",
  'class:"org/lang/impl/JavaFieldAccessMutate"
} external;
```


Describes a Java method, which provides an implementation of a Ballerina function of which the body is marked as
`external`. If the Ballerina function body is marked as `external`, it means that the implementation of the
function is not provided in the Ballerina source module.

The following code snippet shows an example usage of this annotation. Here, the `getUUID` Ballerina function's
implementation is provided by the `java.util.UUID.randomUUID` static method.
```ballerina
function getUUID() returns handle = @java:Method {
    name: "randomUUID",
    'class: "java.util.UUID"
} external;
```
The `name` field is optional. If it is not provided, the name of the Java method is inferred
from the Ballerina function.


This is used for making a function observable.
Can be applied to functions which are not observable by default to make them observable.

In the XML-record conversion, this annotation can be used to add XML attribute using the `xmldata:toXML` API and
validate the XML attribute with record fields in the `xmldata:fromXml` API.


The annotation is used to specify the new name of the existing record name or field name according to the XML format.
In the XML-record conversion, this annotation can be used to override the default XML element name using the
`xmldata:toXML` API and validate the overridden XML element name with record field using the `xmldata:fromXml` API.


The annotation is used to specify the namespace's prefix and URI of the XML element.
In the XML-record conversion, this annotation can be used to add XML namespace using the `xmldata:toXML` API and
validate the the XML namespace with record in the `xmldata:fromXml` API.


Represents the client Basic Auth provider, which is used to authenticate with an external endpoint by generating a
Basic Auth token against the provided credential configurations.
```ballerina
auth:CredentialsConfig config = {
    username: "tom",
    password: "123"
}
auth:ClientBasicAuthProvider provider = new(config);
```


Represents the file user store based listener Basic Auth provider, which is used to authenticate the provided
credentials against the provided file user store configurations.
```ballerina
auth:ListenerFileUserStoreBasicAuthProvider provider = new;
```
The users are denoted by a section in the `Config.toml` file. The username, password, and the scopes of a particular
user are denoted as keys under the users section as shown below. For multiple users, the complete section has to be
duplicated.
```
[[ballerina.auth.users]]
username = "alice"
password = "password1"
scopes = ["scope1", "scope2"]
```


Represents the LDAP-based listener Basic Auth provider, which is used to authenticate the provided credentials
against the provided LDAP user store configurations. This connects to an active directory or an LDAP, retrieves
the necessary user information, and performs authentication and authorization.

auth:LdapUserStoreConfig config = {
    domainName: "ballerina.io",
    connectionURL: "ldap://localhost:389",
    connectionName: "cn=admin,dc=avix,dc=lk"
};
auth:ListenerLdapUserStoreBasicAuthProvider provider = new(config);
```
