doGetInputStream
protected java.io.InputStream doGetInputStream() throws java.lang.Exception
Description copied from class:AbstractFileObject
Creates an input stream to read the file content from. Is only called ifAbstractFileObject.doGetType()
returnsFileType.FILE
.It is guaranteed that there are no open output streams for this file when this method is called.
The returned stream does not have to be buffered.
- Specified by:
doGetInputStream
in classAbstractFileObject
- Throws:
java.lang.Exception
-
doGetOutputStream
protected java.io.OutputStream doGetOutputStream(boolean bAppend) throws java.lang.Exception
Description copied from class:AbstractFileObject
Creates an output stream to write the file content to. Is only called if:AbstractFileObject.doIsWriteable()
returns true.AbstractFileObject.doGetType()
returnsFileType.FILE
, orAbstractFileObject.doGetType()
returnsFileType.IMAGINARY
, and the file's parent exists and is a folder.
It is guaranteed that there are no open stream (input or output) for this file when this method is called.
The returned stream does not have to be buffered.
This implementation throws an exception.- Overrides:
doGetOutputStream
