public final class FromNetASCIIOutputStream
extends java.io.FilterOutputStream

This class wraps an output stream, replacing all occurrences of <CR><LF> (carriage return followed by a linefeed), which is the NETASCII standard for representing a newline, with the local line separator representation. You would use this class to implement ASCII file transfers requiring conversion from NETASCII.

Because of the translation process, a call to flush() will not flush the last byte written if that byte was a carriage return. A call to close() , however, will flush the carriage return.

FromNetASCIIOutputStream

public FromNetASCIIOutputStream(java.io.OutputStream output)

Creates a FromNetASCIIOutputStream instance that wraps an existing OutputStream.

参数:

output - The OutputStream to wrap.

方法详细资料

write

public void write(int ch)
           throws java.io.IOException

Writes a byte to the stream. Note that a call to this method might not actually write a byte to the underlying stream until a subsequent character is written, from which it can be determined if a NETASCII line separator was encountered. This is transparent to the programmer and is only mentioned for completeness.

覆盖:

write 在类中 java.io.FilterOutputStream

参数:

ch - The byte to write.

抛出:

java.io.IOException - If an error occurs while writing to the underlying stream.

write

public void write(byte[] buffer)
           throws java.io.IOException

Writes a byte array to the stream.

覆盖:

write 在类中 java.io.FilterOutputStream

参数:

buffer - The byte array to write.

抛出:

java.io.IOException - If an error occurs while writing to the underlying stream.

write

public void write(byte[] buffer,
         int offset,
         int length)
           throws java.io.IOException

Writes a number of bytes from a byte array to the stream starting from a given offset.

覆盖:

write 在类中 java.io.FilterOutputStream

参数:

buffer - The byte array to write.

offset - The offset into the array at which to start copying data.

length - The number of bytes to write.

抛出:

java.io.IOException - If an error occurs while writing to the underlying stream.

close

public void close()
           throws java.io.IOException

Closes the stream, writing all pending data.

指定者:

close 在接口中 java.io.Closeable

指定者:

close 在接口中 java.lang.AutoCloseable

覆盖:

close 在类中 java.io.FilterOutputStream

抛出:

java.io.IOException - If an error occurs while closing the stream.
