Метод Описание
BEBufferedRandomAccessFile ( Stream stream, bool isReadOnly ) : System

Constructor. Uses the default value for the byte-buffer size (512 bytes).
BEBufferedRandomAccessFile ( Stream stream, bool isReadOnly, int bufferSize ) : System

Constructor. Always needs a size for the buffer.
BEBufferedRandomAccessFile ( System name, System mode ) : System

Constructor. Uses the default value for the byte-buffer size (512 bytes).
BEBufferedRandomAccessFile ( System name, System mode, int bufferSize ) : System

Constructor. Always needs a size for the buffer.
ToString ( ) : System.String

Returns a string of information about the file and the endianess
readDouble ( ) : double

Reads an IEEE double precision (i.e., 64 bit) floating-point number from the input. Prior to reading, the input should be realigned at the byte level.
readFloat ( ) : float

Reads an IEEE single precision (i.e., 32 bit) floating-point number from the input. Prior to reading, the input should be realigned at the byte level.
readInt ( ) : int

Reads a signed int (i.e., 32 bit) from the input. Prior to reading, the input should be realigned at the byte level.
readLong ( ) : long

Reads a signed long (i.e., 64 bit) from the input. Prior to reading, the input should be realigned at the byte level.
readShort ( ) : short

Reads a signed short (i.e. 16 bit) from the input. Prior to reading, the input should be realigned at the byte level.
readUnsignedInt ( ) : long

Reads an unsigned int (i.e., 32 bit) from the input. It is returned as a long since Java does not have an unsigned short type. Prior to reading, the input should be realigned at the byte level.
readUnsignedShort ( ) : int

Reads an unsigned short (i.e., 16 bit) from the input. It is returned as an int since Java does not have an unsigned short type. Prior to reading, the input should be realigned at the byte level.
writeDouble ( double v ) : void

Writes the IEEE double value v (i.e., 64 bits) to the output. Prior to writing, the output should be realigned at the byte level.
writeFloat ( float v ) : void

Writes the IEEE float value v (i.e., 32 bits) to the output. Prior to writing, the output should be realigned at the byte level.
writeInt ( int v ) : void

Writes the int value of v (i.e., the 32 bits) to the output. Prior to writing, the output should be realigned at the byte level.
writeLong ( long v ) : void

Writes the long value of v (i.e., the 64 bits) to the output. Prior to writing, the output should be realigned at the byte level.
writeShort ( int v ) : void

Writes the short value of v (i.e., 16 least significant bits) to the output. Prior to writing, the output should be realigned at the byte level.

Signed or unsigned data can be written. To write a signed value just pass the short value as an argument. To write unsigned data pass the int value as an argument (it will be automatically casted, and only the 16 least significant bits will be written).
