Constructor Summary
`XMLInputSource(java.lang.String publicId, java.lang.String systemId, java.lang.String baseSystemId)` Constructs an input source from just the public and system identifiers, leaving resolution of the entity and opening of the input stream up to the caller.
`XMLInputSource(java.lang.String publicId, java.lang.String systemId, java.lang.String baseSystemId, java.io.InputStream byteStream, java.lang.String encoding)` Constructs an input source from a byte stream.
`XMLInputSource(java.lang.String publicId, java.lang.String systemId, java.lang.String baseSystemId, java.io.Reader charStream, java.lang.String encoding)` Constructs an input source from a character stream.
`XMLInputSource(XMLResourceIdentifier resourceIdentifier)` Constructs an input source from a XMLResourceIdentifier object, leaving resolution of the entity and opening of the input stream up to the caller.

Method Summary
`java.lang.String` | `getBaseSystemId()` Returns the base system identifier.
`java.io.InputStream` | `getByteStream()` Returns the byte stream.
`java.io.Reader` | `getCharacterStream()` Returns the character stream.
`java.lang.String` | `getEncoding()` Returns the encoding of the stream, or null if not known.
`java.lang.String` | `getPublicId()` Returns the public identifier.
`java.lang.String` | `getSystemId()` Returns the system identifier.
`void` | `setBaseSystemId(java.lang.String baseSystemId)` Sets the base system identifier.
`void` | `setByteStream(java.io.InputStream byteStream)` Sets the byte stream.
`void` | `setCharacterStream(java.io.Reader charStream)` Sets the character stream.
`void` | `setEncoding(java.lang.String encoding)` Sets the encoding of the stream.
`void` | `setPublicId(java.lang.String publicId)` Sets the public identifier.
`void` | `setSystemId(java.lang.String systemId)` Sets the system identifier.

Constructor Detail

### XMLInputSource

    public XMLInputSource(java.lang.String publicId,
                          java.lang.String systemId,
                          java.lang.String baseSystemId)

  Constructs an input source from just the public and system identifiers, leaving resolution of the entity and opening of the input stream up to the caller.
  Parameters:
    `publicId` - The public identifier, if known.
    `systemId` - The system identifier. This value should always be set, if possible, and can be relative or absolute. If the system identifier is relative, then the base system identifier should be set.
    `baseSystemId` - The base system identifier. This value should always be set to the fully expanded URI of the base system identifier, if possible.

### XMLInputSource

    public XMLInputSource(XMLResourceIdentifier resourceIdentifier)

  Constructs an input source from a XMLResourceIdentifier object, leaving resolution of the entity and opening of the input stream up to the caller.
  Parameters:
    `resourceIdentifier` - the XMLResourceIdentifier containing the information

### XMLInputSource

    public XMLInputSource(java.lang.String publicId,
                          java.lang.String systemId,
                          java.lang.String baseSystemId,
                          java.io.InputStream byteStream,
                          java.lang.String encoding)

  Constructs an input source from a byte stream.
  Parameters:
    `publicId` - The public identifier, if known.
    `systemId` - The system identifier. This value should always be set, if possible, and can be relative or absolute. If the system identifier is relative, then the base system identifier should be set.
    `baseSystemId` - The base system identifier. This value should always be set to the fully expanded URI of the base system identifier, if possible.
    `byteStream` - The byte stream.
    `encoding` - The encoding of the byte stream, if known.

### XMLInputSource

    public XMLInputSource(java.lang.String publicId,
                          java.lang.String systemId,
                          java.lang.String baseSystemId,
                          java.io.Reader charStream,
                          java.lang.String encoding)

  Constructs an input source from a character stream.
  Parameters:
    `publicId` - The public identifier, if known.
    `systemId` - The system identifier. This value should always be set, if possible, and can be relative or absolute. If the system identifier is relative, then the base system identifier should be set.
    `baseSystemId` - The base system identifier. This value should always be set to the fully expanded URI of the base system identifier, if possible.
    `charStream` - The character stream.
    `encoding` - The original encoding of the byte stream used by the reader, if known.

Method Detail

### setPublicId

    public void setPublicId(java.lang.String publicId)

  Sets the public identifier.
  Parameters:
    `publicId` - The new public identifier.

### getPublicId

    public java.lang.String getPublicId()

  Returns the public identifier.

### setSystemId

    public void setSystemId(java.lang.String systemId)

  Sets the system identifier.
  Parameters:
    `systemId` - The new system identifier.

### getSystemId

    public java.lang.String getSystemId()

  Returns the system identifier.

### setBaseSystemId

    public void setBaseSystemId(java.lang.String baseSystemId)

  Sets the base system identifier.
  Parameters:
    `baseSystemId` - The new base system identifier.

### getBaseSystemId

    public java.lang.String getBaseSystemId()

  Returns the base system identifier.

### setByteStream

    public void setByteStream(java.io.InputStream byteStream)

  Sets the byte stream. If the byte stream is not already opened when this object is instantiated, then the code that opens the stream should also set the byte stream on this object. Also, if the encoding is auto-detected, then the encoding should also be set on this object.
  Parameters:
    `byteStream` - The new byte stream.

### getByteStream

    public java.io.InputStream getByteStream()

  Returns the byte stream.

### setCharacterStream

    public void setCharacterStream(java.io.Reader charStream)

  Sets the character stream. If the character stream is not already opened when this object is instantiated, then the code that opens the stream should also set the character stream on this object. Also, the encoding of the byte stream used by the reader should also be set on this object, if known.
  Parameters:
    `charStream` - The new character stream.
  See Also:
    `setEncoding(java.lang.String)`

### getCharacterStream

    public java.io.Reader getCharacterStream()

  Returns the character stream.

### setEncoding

    public void setEncoding(java.lang.String encoding)

  Sets the encoding of the stream.
  Parameters:
    `encoding` - The new encoding.

### getEncoding

    public java.lang.String getEncoding()

  Returns the encoding of the stream, or null if not known.
