Known direct subclasses [Locator2Impl](https://developer.android.com/reference/org/xml/sax/ext/Locator2Impl) [Locator2Impl](https://developer.android.com/reference/org/xml/sax/ext/Locator2Impl) SAX2 extension helper for holding additional Entity information, implementing the `https://developer.android.com/reference/org/xml/sax/ext/Locator2` interface.

Provide an optional convenience implementation of Locator.

This class is available mainly for application writers, who
can use it to make a persistent snapshot of a locator at any
point during a document parse:

```
 Locator locator;
 Locator startloc;

 public void setLocator (Locator locator)
 {
         // note the locator
   this.locator = locator;
 }

 public void startDocument ()
 {
         // save the location of the start of the document
         // for future use.
   Locator startloc = new LocatorImpl(locator);
 }
```

Normally, parser writers will not use this class, since it
is more efficient to provide location information only when
requested, rather than constantly updating a Locator object.

## Public constructors

### LocatorImpl

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public LocatorImpl ()
```

Zero-argument constructor.

This will not normally be useful, since the main purpose
of this class is to make a snapshot of an existing Locator.

<br />

### LocatorImpl

Added in [API level 1](https://developer.android.com/guide/topics/manifest/uses-sdk-element#ApiLevels)

```
public LocatorImpl (Locator locator)
```

Copy constructor.

When the original locator changes, this copy will still keep
the original values (and it can be used outside the scope of
DocumentHandler methods).

<br />

<br />

| Parameters ||
|---|---|
| `locator` | `Locator`: The locator to copy. <br /> |
