LargeText

public LargeText(File file,
 boolean completed)

LargeText

public LargeText(File file,
 boolean completed,
 boolean transparentGunzip)

Parameters:

transparentGunzip - if set to true, this class will detect if the given file is compressed with GZIP. If so, it will transparently uncompress its content during read-access. Do note that the underlying file is not altered and remains compressed.

Since:

1.196

LargeText

public LargeText(File file,
 Charset charset,
 boolean completed)

LargeText

public LargeText(File file,
 Charset charset,

 boolean transparentGunzip)

Parameters:

transparentGunzip - if set to true, this class will detect if the given file is compressed with GZIP. If so, it will transparently uncompress its content during read-access. Do note that the underlying file is not altered and remains compressed.

Since:

LargeText

public LargeText(ByteBuffer memory,
 Charset charset,
 boolean completed)

Method Details

markAsComplete

public void markAsComplete()

isComplete

public boolean isComplete()

length

public long length()

readAll

public Reader readAll()
               throws IOException

Returns Reader for reading the raw bytes.

Throws:

IOException

writeLogTo

public long writeLogTo(long start,
 Writer w)
                throws IOException

Throws:

IOException

writeLogTo

public long writeLogTo(long start,
 OutputStream out)
                throws IOException

Writes the tail portion of the file to the OutputStream.

Parameters:

start - The byte offset in the input file where the write operation starts.

Returns:

if the file is still being written, this method writes the file until the last newline character and returns the offset to start the next write operation.

Throws:

EOFException - if the start position is larger than the file size

IOException

doProgressText

public void doProgressText(StaplerRequest req,
 StaplerResponse rsp)
                    throws IOException

Implements the progressive text handling. This method is used as a "web method" with progressiveText.jelly.

Throws:

IOException

setContentType

protected void setContentType(StaplerResponse rsp)

createWriter

protected Writer createWriter(StaplerRequest req,
 StaplerResponse rsp,
 long size)
                       throws IOException

Throws:

IOException
