flush	back to summary
public void flush() throws IOException Overrides java.io.OutputStream.flush. Implements java.io.Flushable.flush. Doc from java.io.OutputStream.flush. Flushes this output stream and forces any buffered output bytes to be written out. The general contract of `flush` is that calling it is an indication that, if any bytes previously written have been buffered by the implementation of the output stream, such bytes should immediately be written to their intended destination. If the intended destination of this stream is an abstraction provided by the underlying operating system, for example a file, then flushing the stream guarantees only that bytes previously written to the stream are passed to the operating system for writing; it does not guarantee that they are actually written to a physical device such as a disk drive. Annotations @Override Exceptions IOException: if an I/O error occurs.

isReady	back to summary
public boolean isReady() Implements abstract jakarta.servlet.ServletOutputStream.isReady. Doc from jakarta.servlet.ServletOutputStream.isReady. Returns true if data can be written without blocking else returns false. If this method returns false and a `WriteListener` has been set with `setWriteListener(WriteListener)`, then container will subsequently invoke `WriteListener#onWritePossible()` once a write operation becomes possible without blocking. Other than the initial call, `WriteListener#onWritePossible()` will only be called if and only if this method is called and returns false. Returns:boolean `true` if data can be written without blocking, otherwise returns `false`. Annotations @Override

write	back to summary
public void write(int b) Implements abstract java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes the specified byte to this output stream. The general contract for `write` is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument `b`. The 24 high-order bits of `b` are ignored. Parameters b:int the `byte`. Annotations @Override

Writes the specified byte to this output stream. The general contract for write is that one byte is written to the output stream. The byte to be written is the eight low-order bits of the argument b. The 24 high-order bits of b are ignored.

Parameters

b:int: the byte.

write	back to summary
public void write(byte[] buf, int offset, int len) throws IOException Overrides java.io.OutputStream.write. Doc from java.io.OutputStream.write. Writes `len` bytes from the specified byte array starting at offset `off` to this output stream. The general contract for `write(b, off, len)` is that some of the bytes in the array `b` are written to the output stream in order; element `b[off]` is the first byte written and `b[off+len-1]` is the last byte written by this operation. If `b` is `null`, a `NullPointerException` is thrown. If `off` is negative, or `len` is negative, or `off+len` is greater than the length of the array `b`, then an `IndexOutOfBoundsException` is thrown. Parameters buf:byte[] the data. offset:int the start offset in the data. len:int the number of bytes to write. Annotations @Override Exceptions IOException: if an I/O error occurs. In particular, an `IOException` is thrown if the output stream is closed.

public void write(byte[] buf, int offset, int len) throws IOException

Overrides java.io.OutputStream.write.

Doc from java.io.OutputStream.write.

Writes len bytes from the specified byte array starting at offset off to this output stream. The general contract for write(b, off, len) is that some of the bytes in the array b are written to the output stream in order; element b[off] is the first byte written and b[off+len-1] is the last byte written by this operation.

If b is null, a NullPointerException is thrown.

If off is negative, or len is negative, or off+len is greater than the length of the array b, then an IndexOutOfBoundsException is thrown.

Parameters

buf:byte[]: the data.
offset:int: the start offset in the data.
len:int: the number of bytes to write.

Exceptions

IOException:: if an I/O error occurs. In particular, an IOException is thrown if the output stream is closed.
