jdk.io.RandomAccessFile
Instances of this class support both reading and writing to a random access file. A random access file behaves like a large array of bytes stored in the file system. There is a kind of cursor, or index into the implied array, called the file pointer; input operations read bytes starting at the file pointer and advance the file pointer past the bytes read. If the random access file is created in read/write mode, then output operations are also available; output operations write bytes starting at the file pointer and advance the file pointer past the bytes written. Output operations that write past the current end of the implied array cause the array to be extended. The file pointer can be read by the getFilePointer method and set by the seek method.
It is generally true of all the reading routines in this class that if end-of-file is reached before the desired number of bytes has been read, an EOFException (which is a kind of IOException) is thrown. If any byte cannot be read for any reason other than end-of-file, an IOException other than EOFException is thrown. In particular, an IOException may be thrown if the stream has been closed.

->random-access-fileclj
(->random-access-file name mode)Constructor.
Creates a random access file stream to read from, and optionally to write to, a file with the specified name. A new FileDescriptor object is created to represent the connection to the file.
The mode argument specifies the access mode with which the file is to be opened. The permitted values and their meanings are as specified for the RandomAccessFile(File,String) constructor.
If there is a security manager, its checkRead method is called with the name argument as its argument to see if read access to the file is allowed. If the mode allows writing, the security manager's checkWrite method is also called with the name argument as its argument to see if write access to the file is allowed.

mode - the access mode - java.lang.String

v - a char value to be written. - int
throws: java.io.IOException - if an I/O error occurs.
Writes a char to the file as a two-byte value, high byte first. The write starts at the current position of the file pointer. v - a char value to be written. - `int` throws: java.io.IOException - if an I/O error occurs.
write-charsclj
(write-chars this s)Writes a string to the file as a sequence of characters. Each character is written to the data output stream as if by the writeChar method. The write starts at the current position of the file pointer.
s - a String value to be written. - java.lang.String
throws: java.io.IOException - if an I/O error occurs.
Writes a string to the file as a sequence of characters. Each character is written to the data output stream as if by the writeChar method. The write starts at the current position of the file pointer. s - a String value to be written. - `java.lang.String` throws: java.io.IOException - if an I/O error occurs.
write-doubleclj
(write-double this v)Converts the double argument to a long using the doubleToLongBits method in class Double, and then writes that long value to the file as an eight-byte quantity, high byte first. The write starts at the current position of the file pointer.
v - a double value to be written. - double
throws: java.io.IOException - if an I/O error occurs.
Converts the double argument to a long using the doubleToLongBits method in class Double, and then writes that long value to the file as an eight-byte quantity, high byte first. The write starts at the current position of the file pointer. v - a double value to be written. - `double` throws: java.io.IOException - if an I/O error occurs.
write-floatclj
(write-float this v)Converts the float argument to an int using the floatToIntBits method in class Float, and then writes that int value to the file as a four-byte quantity, high byte first. The write starts at the current position of the file pointer.
v - a float value to be written. - float
throws: java.io.IOException - if an I/O error occurs.
Converts the float argument to an int using the floatToIntBits method in class Float, and then writes that int value to the file as a four-byte quantity, high byte first. The write starts at the current position of the file pointer. v - a float value to be written. - `float` throws: java.io.IOException - if an I/O error occurs.
write-intclj
(write-int this v)Writes an int to the file as four bytes, high byte first. The write starts at the current position of the file pointer.
v - an int to be written. - int
throws: java.io.IOException - if an I/O error occurs.
Writes an int to the file as four bytes, high byte first. The write starts at the current position of the file pointer. v - an int to be written. - `int` throws: java.io.IOException - if an I/O error occurs.
write-longclj
(write-long this v)Writes a long to the file as eight bytes, high byte first. The write starts at the current position of the file pointer.
v - a long to be written. - long
throws: java.io.IOException - if an I/O error occurs.
Writes a long to the file as eight bytes, high byte first. The write starts at the current position of the file pointer. v - a long to be written. - `long` throws: java.io.IOException - if an I/O error occurs.
write-shortclj
(write-short this v)Writes a short to the file as two bytes, high byte first. The write starts at the current position of the file pointer.
v - a short to be written. - int
throws: java.io.IOException - if an I/O error occurs.
Writes a short to the file as two bytes, high byte first. The write starts at the current position of the file pointer. v - a short to be written. - `int` throws: java.io.IOException - if an I/O error occurs.
write-utfclj
(write-utf this str)Writes a string to the file using modified UTF-8 encoding in a machine-independent manner.
First, two bytes are written to the file, starting at the current file pointer, as if by the writeShort method giving the number of bytes to follow. This value is the number of bytes actually written out, not the length of the string. Following the length, each character of the string is output, in sequence, using the modified UTF-8 encoding for each character.
str - a string to be written. - java.lang.String
throws: java.io.IOException - if an I/O error occurs.
