Class MFLSource
java.lang.Object
com.bea.wli.sb.sources.MFLSource
- All Implemented Interfaces:
- Source
public class MFLSource
- extends 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.
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.

MFLSource
public MFLSource(org.apache.xmlbeans.XmlObject xml,
Ref mflRef)
getMFLRef
public Ref getMFLRef()
getXmlObject
public org.apache.xmlbeans.XmlObject getXmlObject()
getInputStream
public InputStream getInputStream(TransformOptions options)
throws 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:
IOException
TransformException
writeTo
public void writeTo(OutputStream out,
TransformOptions options)
throws 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.
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 writtenoptions
- TransformOptions used to affect the serialization
- Throws:
IOException
TransformException
getInstance
public static MFLSource getInstance(InputStream in,
Ref mflRef)
throws TransformException
- Throws:
TransformException
getInstance
public static MFLSource getInstance(org.apache.xmlbeans.XmlObject xml,
