| BEBufferedRandomAccessFile | | public BEBufferedRandomAccessFile(File file, String mode, int bufferSize) throws IOException(Code) | | Constructor. Always needs a size for the buffer.
Parameters:
file - The file associated with the buffer
Parameters:
mode - "r" for read, "rw" or "rw+" for read and write mode ("rw+"opens the file for update whereas "rw" removes itbefore. So the 2 modes are different only if the filealready exists).
Parameters:
bufferSize - The number of bytes to buffer
exception:
java.io.IOException - If an I/O error ocurred. |

| toString | | public String toString()(Code) | | Returns a string of information about the file and the endianess
|
| writeDouble | | final public void writeDouble(double v) throws IOException(Code) | | 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.
Parameters:
v - The value to write to the output
exception:
java.io.IOException - If an I/O error ocurred. |
| writeFloat | | final public void writeFloat(float v) throws IOException(Code) | | 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.
Parameters:
v - The value to write to the output
exception:
java.io.IOException - If an I/O error ocurred. |
| writeInt | | final public void writeInt(int v) throws IOException(Code) | | 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.
Parameters:
v - The value to write to the output
exception:
java.io.IOException - If an I/O error ocurred. |
| writeLong | | final public void writeLong(long v) throws IOException(Code) | | 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.
Parameters:
v - The value to write to the output
exception:
java.io.IOException - If an I/O error ocurred. |
| writeShort | | final public void writeShort(int v) throws IOException(Code) | | 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).
Parameters:
v - The value to write to the output
exception:
java.io.IOException - If an I/O error ocurred. |
