Method Detail
-
setIsClosing
public abstract void setIsClosing(boolean b)
-
getBufferSize
public abstract int getBufferSize()
Query the amount of data this stream is configured to buffer before an automatic write happens.- Returns:
- int
-
setBufferSize
public abstract void setBufferSize(int size)
Set the amount of data to buffer internally before the stream itself initiates a flush. A zero size means no buffer is done, each write call will flush data.- Parameters:
size-- Throws:
java.lang.IllegalStateException- if already writing data or closed
-
clear
public abstract void clear()
Clear any current buffer content in the stream.
-
getBytesWritten
public abstract long getBytesWritten()
Query the amount of bytes written so far.- Returns:
- long
-
getBufferedCount
public abstract long getBufferedCount()
Query the amount of bytes currently buffered so far.- Returns:
- long
-
hasBufferedContent
public abstract boolean hasBufferedContent()
Test whether this stream has any current data buffered, waiting to be written out.- Returns:
- boolean
-
writeFile
public abstract void writeFile(java.nio.channels.FileChannel fc) throws java.io.IOExceptionWrite a file channel onto the output stream.- Parameters:
fc-- Throws:
java.io.IOException
-
flushHeaders
public abstract void flushHeaders() throws java.io.IOExceptionWrite the current set of response headers. If the headers have already been sent, this is a no-op.- Throws:
java.io.IOException
-
flushBuffers
public abstract void flushBuffers() throws java.io.IOExceptionFlush the output array of buffers to the network below.- Throws:
java.io.IOException
-
isClosed
public abstract boolean isClosed()
Query whether this stream is closed already or not.- Returns:
- boolean
-
flush
public abstract void flush(boolean ignoreFlag) throws java.io.IOException- Parameters:
ignoreFlag-- Throws:
java.io.IOException
-
setContentLength
public abstract void setContentLength(long length)
- Parameters:
length-
