Class MFLSource

java.lang.Object
com.bea.wli.sb.sources.MFLSource

All Implemented Interfaces:

Source

public class MFLSource

extends java.lang.Object

implements Source

This class represents MFL content. MFL data is essentially binary data that has some logical structure imposed on it by an MFL definition. CSV is simple example of MFL data, but the structure can be arbitrarily complex. The logical/in-memory representation of the data is an XML document, but it's serialized representation is the raw "unstructured" binary data. <P/> An MFLSource allows for both views of the MFL data. The content is kept in it's logical form as an XmlObject and this can be obtained from the MFLSource. However, the Source serialization methods writeTo() and getInputStream() will yield the binary form.

getMFLRef

public Ref getMFLRef()

getXmlObject

public org.apache.xmlbeans.XmlObject getXmlObject()

getInputStream

public java.io.InputStream getInputStream(TransformOptions options)
                                   throws java.io.IOException,
                                          TransformException

Description copied from interface: Source

Returns streaming byte-baseed representation of the Source's content. The representation of that serialization is entirely up to the Source. Note that this method may involve an internal transformation, although it should not in any way change the underlying content.

Specified by:

getInputStream in interface Source

Parameters:

options - Options used to affect the serialization

Returns:

an InputStream for retrieving the serialized content

Throws:

java.io.IOException

TransformException

writeTo

public void writeTo(java.io.OutputStream out,
                    TransformOptions options)
             throws java.io.IOException,
                    TransformException

Description copied from interface: Source

Serializes the Source's content to a byte-based stream. The representation of that serialization is entirely up to the Source. The Source is forbidden from closing the provided OutputStream, although it is allowed to flush it. However, flushing the stream should be left to the caller, if possible. <p/> Note that this method may involve an internal transformation, although it should not in any way change the underlying content.

Specified by:

writeTo in interface Source

Parameters:

out - the OutputStream to which serialized content will be written

options - TransformOptions used to affect the serialization

Throws:

java.io.IOException

TransformException

getInstance

public static MFLSource getInstance(java.io.InputStream in,
                                    Ref mflRef)
                             throws TransformException

Throws:

TransformException

getInstance

public static MFLSource getInstance(org.apache.xmlbeans.XmlObject xml,
                                    Ref mflRef)
