Method Detail

doGetInputStream
protected java.io.InputStream doGetInputStream(int bufferSize) 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.
- Overrides:
doGetInputStream
in classAbstractFileObject<GzipFileSystem>
- Parameters:
bufferSize
- Buffer size hint.- Returns:
- An InputStream to read the file content.
- Throws:
java.lang.Exception
- if an error occurs.
-
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.
The returned stream does not have to be buffered.
This implementation throws an exception.
- Overrides:
doGetOutputStream
in classAbstractFileObject<GzipFileSystem>
- Parameters:
bAppend
- true if the file should be appended to, false if it should be overwritten.- Returns:
- An OutputStream to write to the file.
- Throws:
java.lang.Exception
- if an error occurs.
