 org.xml.sax.InputSource
| InputSource | | public class InputSource (Code) | | A single input source for an XML entity.
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 will deliver this
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; if not, the parser will use
a byte stream, if available; 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).

| Constructor Summary | |
| public | InputSource()
Zero-argument default constructor. | | public | InputSource(String systemId)
Create a new input source with a system identifier. | | public | InputSource(InputStream byteStream)
Create a new input source with a byte stream. | | public | InputSource(Reader characterStream)
Create a new input source with a character stream. |
| getPublicId | | public String getPublicId()(Code) | | Get the public identifier for this input source.
The public identifier, or null if none was supplied.
See Also: InputSource.setPublicId |
| getSystemId | | public String getSystemId()(Code) | | Get the system identifier for this input source.
The getEncoding method will return the character encoding
of the object pointed to, or null if unknown.
If the system ID is a URL, it will be fully resolved.
The system identifier.
See Also: InputSource.setSystemId
See Also: InputSource.getEncoding |
| setByteStream | | public void setByteStream(InputStream byteStream)(Code) | | 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.
Parameters:
byteStream - A byte stream containing an XML document orother entity.
See Also: InputSource.setEncoding
See Also: InputSource.getByteStream
See Also: InputSource.getEncoding
See Also: java.io.InputStream |
| setCharacterStream | | public void setCharacterStream(Reader characterStream)(Code) | | 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.
Parameters:
characterStream - The character stream containing theXML document or other entity.
See Also: InputSource.getCharacterStream
See Also: java.io.Reader |
| setEncoding | | public void setEncoding(String encoding)(Code) | | 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.
Parameters:
encoding - A string describing the character encoding.
See Also: InputSource.setSystemId
See Also: InputSource.setByteStream
See Also: InputSource.getEncoding |
| setSystemId | | public void setSystemId(String systemId)(Code) | | 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 ID is a URL, it must be fully resolved.
Parameters:
systemId - The system identifier as a string.
