## Public constructors

### Domain

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)  
Also in [C Extensions 24](https://developer.android.com/sdkExtensions)

```
public Domain (String hostname, 
                boolean subdomainsIncluded)
```

Constructor for a Domain object.

<br />

| Parameters ||
|---|---|
| `hostname` | `String`: the hostname of the domain. This value cannot be `null`. <br /> |
| `subdomainsIncluded` | `boolean`: whether subdomains are considered part of this domain. <br /> |

## Public methods

### equals

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)

```
public boolean equals (Object other)
```

Indicates whether some other object is "equal to" this one.


The `equals` method implements an equivalence relation
on non-null object references:

- It is *reflexive*: for any non-null reference value `x`, `x.equals(x)` should return `true`.
- It is *symmetric*: for any non-null reference values `x` and `y`, `x.equals(y)` should return `true` if and only if `y.equals(x)` returns `true`.
- It is *transitive*: for any non-null reference values `x`, `y`, and `z`, if `x.equals(y)` returns `true` and `y.equals(z)` returns `true`, then `x.equals(z)` should return `true`.
- It is *consistent*: for any non-null reference values `x` and `y`, multiple invocations of `x.equals(y)` consistently return `true` or consistently return `false`, provided no information used in `equals` comparisons on the objects is modified.
- For any non-null reference value `x`, `x.equals(null)` should return `false`.


An equivalence relation partitions the elements it operates on
into *equivalence classes*; all the members of an
equivalence class are equal to each other. Members of an
equivalence class are substitutable for each other, at least
for some purposes.

<br />

| Parameters ||
|---|---|
| `other` | `Object`: This value may be `null`. <br /> |

| Returns ||
|---|---|
| `boolean` | `true` if this object is the same as the obj argument; `false` otherwise. <br /> |

### getHostname

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)  
Also in [C Extensions 24](https://developer.android.com/sdkExtensions)

```
public String getHostname ()
```

<br />

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | the hostname of the domain. This value cannot be `null`. <br /> |

### hashCode

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)

```
public int hashCode ()
```

Returns a hash code value for the object. This method is
supported for the benefit of hash tables such as those provided by
`https://developer.android.com/reference/java/util/HashMap`.


The general contract of `hashCode` is:

- Whenever it is invoked on the same object more than once during an execution of a Java application, the `hashCode` method must consistently return the same integer, provided no information used in `equals` comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
- If two objects are equal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce the same integer result.
- It is *not* required that if two objects are unequal according to the `https://developer.android.com/reference/java/lang/Object#equals(java.lang.Object)` method, then calling the `hashCode` method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.

<br />

<br />

| Returns ||
|---|---|
| `int` | a hash code value for this object. <br /> |

### isLocalhost

Added in [version 37.2](https://developer.android.com/topic/libraries/support-library/revisions)  
Also in [C Extensions 24](https://developer.android.com/sdkExtensions)

```
public boolean isLocalhost ()
```

<br />

<br />

| Returns ||
|---|---|
| `boolean` | true if the domain is considered a localhost domain. <br /> |
