Class StreamSource

java.lang.Object  |  +--javax.xml.transform.stream.StreamSource

All Implemented Interfaces:

Source

public classStreamSource

extends java.lang.Object

implementsSource

Acts as an holder for a transformation Source in the form of a stream of XML markup.

FEATURE

public static final java.lang.StringFEATURE

IfTransformerFactory.getFeature(java.lang.String) returns true when passed this value as an argument, the Transformer supports Source input of this type.

StreamSource

publicStreamSource()

Zero-argument default constructor. If this constructor is used, and no other method is called, the transformer will assume an empty input tree, with a default root node.

StreamSource

publicStreamSource(java.io.InputStream inputStream)

Construct a StreamSource from a byte stream. Normally, a stream should be used rather than a reader, so the XML parser can resolve character encoding specified by the XML declaration.

If this constructor is used to process a stylesheet, normally setSystemId should also be called, so that relative URI references can be resolved.

Parameters:

inputStream - A valid InputStream reference to an XML stream.

StreamSource

publicStreamSource(java.io.InputStream inputStream,                    java.lang.String systemId)

Construct a StreamSource from a byte stream. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration.

This constructor allows the systemID to be set in addition to the input stream, which allows relative URIs to be processed.

Parameters:

inputStream - A valid InputStream reference to an XML stream.

systemId - Must be a String that conforms to the URI syntax.

StreamSource

publicStreamSource(java.io.Reader reader)

Construct a StreamSource from a character reader. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.

Parameters:

reader - A valid Reader reference to an XML character stream.

StreamSource

publicStreamSource(java.io.Reader reader,                    java.lang.String systemId)

Construct a StreamSource from a character reader. Normally, a stream should be used rather than a reader, so that the XML parser may resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.

Parameters:

reader - A valid Reader reference to an XML character stream.

systemId - Must be a String that conforms to the URI syntax.

StreamSource

publicStreamSource(java.lang.String systemId)

Construct a StreamSource from a URL.

Parameters:

systemId - Must be a String that conforms to the URI syntax.

StreamSource

publicStreamSource(java.io.File f)

Construct a StreamSource from a File.

Parameters:

f - Must a non-null File reference.

setInputStream

public voidsetInputStream(java.io.InputStream inputStream)

Set the byte stream to be used as input. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration.

If this Source object is used to process a stylesheet, normally setSystemId should also be called, so that relative URL references can be resolved.

Parameters:

inputStream - A valid InputStream reference to an XML stream.

getInputStream

public java.io.InputStreamgetInputStream()

Get the byte stream that was set with setByteStream.

Returns:

The byte stream that was set with setByteStream, or null if setByteStream or the ByteStream constructor was not called.

setReader

public voidsetReader(java.io.Reader reader)

Set the input to be a character reader. Normally, a stream should be used rather than a reader, so that the XML parser can resolve character encoding specified by the XML declaration. However, in many cases the encoding of the input stream is already resolved, as in the case of reading XML from a StringReader.

Parameters:

reader - A valid Reader reference to an XML CharacterStream.

getReader

public java.io.ReadergetReader()

Get the character stream that was set with setReader.

Returns:

The character stream that was set with setReader, or null if setReader or the Reader constructor was not called.

setPublicId

public voidsetPublicId(java.lang.String publicId)

Set the public identifier for this Source.

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

Parameters:

publicId - The public identifier as a string.

getPublicId

public java.lang.StringgetPublicId()

Get the public identifier that was set with setPublicId.

Returns:

The public identifier that was set with setPublicId, or null if setPublicId was not called.

setSystemId

public voidsetSystemId(java.lang.String systemId)

Set the system identifier for this 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).

Specified by:

setSystemId in interfaceSource

Parameters:

systemId - The system identifier as a URL string.

getSystemId

public java.lang.StringgetSystemId()

Get the system identifier that was set with setSystemId.

Specified by:

getSystemId in interfaceSource

Returns:

The system identifier that was set with setSystemId, or null if setSystemId was not called.

setSystemId

public voidsetSystemId(java.io.File f)

Set the system ID from a File reference.

Parameters:

f - Must a non-null File reference.
