*** ** * ** ***

A single input source for an XML entity.

> *This module, both source code and documentation, is in the
> Public Domain, and comes with **NO WARRANTY**.* See <http://www.saxproject.org> for further information.

This class allows a SAX application to encapsulate information
about an input source in a single object, which may include
a public identifier, a system identifier, a byte stream (possibly
with a specified encoding), and/or a character stream.

There are two places that the application can deliver an
input source to the parser: as the argument to the Parser.parse
method, or as the return value of the EntityResolver.resolveEntity
method.

The SAX parser will use the InputSource object to determine how
to read XML input. If there is a character stream available, the
parser will read that stream directly, disregarding any text
encoding declaration found in that stream.
If there is no character stream, but there is
a byte stream, the parser will use that byte stream, using the
encoding specified in the InputSource or else (if no encoding is
specified) autodetecting the character encoding using an algorithm
such as the one in the XML specification. If neither a character
stream nor a
byte stream is available, the parser will attempt to open a URI
connection to the resource identified by the system
identifier.

An InputSource object belongs to the application: the SAX parser
shall never modify it in any way (it may modify a copy if
necessary). However, standard processing of both byte and
character streams is to close them on as part of end-of-parse cleanup,
so applications should not attempt to re-use such streams after they
have been handed to a parser.

```
public String getPublicId ()
```

Get the public identifier for this input source.

<br />

| Returns ||
|---|---|
| `https://developer.android.com/reference/java/lang/String` | The public identifier, or null if none was supplied. <br /> |

**See also:**

```
public String getSystemId ()

### setByteStream

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

```
public void setByteStream (InputStream byteStream)
```

Set the byte stream for this input source.

The SAX parser will ignore this if there is also a character
stream specified, but it will use a byte stream in preference
to opening a URI connection itself.

If the application knows the character encoding of the
byte stream, it should set it with the setEncoding method.

<br />

<br />

| Parameters ||
|---|---|
| `byteStream` | `InputStream`: A byte stream containing an XML document or other entity. <br /> |

**See also:**

- `https://developer.android.com/reference/org/xml/sax/InputSource#setEncoding(java.lang.String)`
- `https://developer.android.com/reference/org/xml/sax/InputSource#getByteStream()`
- `https://developer.android.com/reference/org/xml/sax/InputSource#getEncoding()`
- `https://developer.android.com/reference/java/io/InputStream`

### setCharacterStream

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

```
public void setCharacterStream (Reader characterStream)
```

Set the character stream for this input source.

If there is a character stream specified, the SAX parser
will ignore any byte stream and will not attempt to open
a URI connection to the system identifier.

<br />

<br />

| Parameters ||
|---|---|
| `characterStream` | `Reader`: The character stream containing the XML document or other entity. <br /> |

**See also:**

- `https://developer.android.com/reference/org/xml/sax/InputSource#getCharacterStream()`
- `https://developer.android.com/reference/java/io/Reader`

### setEncoding

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

```
public void setEncoding (String encoding)
```

Set the character encoding, if known.

The encoding must be a string acceptable for an
XML encoding declaration (see section 4.3.3 of the XML 1.0
recommendation).

This method has no effect when the application provides a
character stream.

<br />

<br />

| Parameters ||
|---|---|
| `encoding` | `String`: A string describing the character encoding. <br /> |

**See also:**

- `https://developer.android.com/reference/org/xml/sax/InputSource#setSystemId(java.lang.String)`
- `https://developer.android.com/reference/org/xml/sax/InputSource#setByteStream(java.io.InputStream)`
- `https://developer.android.com/reference/org/xml/sax/InputSource#getEncoding()`

### setPublicId

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

```
public void setPublicId (String publicId)
```

Set the public identifier for this input source.

The public identifier is always optional: if the application
writer includes one, it will be provided as part of the
location information.

<br />

<br />

| Parameters ||
|---|---|
| `publicId` | `String`: The public identifier as a string. <br /> |

**See also:**

- `https://developer.android.com/reference/org/xml/sax/InputSource#getPublicId()`
- `https://developer.android.com/reference/org/xml/sax/Locator#getPublicId()`
- `https://developer.android.com/reference/org/xml/sax/SAXParseException#getPublicId()`

### setSystemId

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

```
public void setSystemId (String systemId)
```

Set the system identifier for this input source.

The system identifier is optional if there is a byte stream
or a character stream, but it is still useful to provide one,
since the application can use it to resolve relative URIs
and can include it in error messages and warnings (the parser
will attempt to open a connection to the URI only if
there is no byte stream or character stream specified).

If the application knows the character encoding of the
object pointed to by the system identifier, it can register
the encoding using the setEncoding method.

If the system identifier is a URL, it must be fully
resolved (it may not be a relative URL).

<br />

<br />

| Parameters ||
|---|---|
| `systemId` | `String`: The system identifier as a string. <br /> |
