public void setLength( long newLength) throws IOException
Sets the length of this fi le.
If the present length of the fi le as returned by the length method is greater than the
newLength argument, then the fi le will be truncated. In this case, if the fi le pointer location as
returned by the getFilePointer method is greater than newLength , then after this method
returns, the fi le pointer location will be equal to newLength .
If the present length of the fi le as returned by the length method is smaller than newLength ,
then the fi le will be extended. In this case, the contents of the extended portion of the fi le are
not defi ned.
public long getFilePointer() throws IOException
Returns the current location of the fi le pointer. Locations are numbered starting with 0 .
public long length() throws IOException
Returns the length of the fi le.
public int read() throws IOException
Reads a byte of data from the fi le and returns it as an integer in the range 0 to 255.
public int read( byte [] a) throws IOException
Reads up to a.length bytes of data from the fi le into the array of bytes. Returns the total
number of bytes read or -1 if the end of the fi le is reached.
public final boolean readBoolean() throws IOException
Reads a boolean value from the fi le and returns that value.
If an attempt is made to read beyond the end of the fi le, an EOFException is thrown.
public final byte readByte() throws IOException
Reads a byte value from the fi le and returns that value.
If an attempt is made to read beyond the end of the fi le, an EOFException is thrown.
public final char readChar() throws IOException
Reads a char value from the fi le and returns that value.
If an attempt is made to read beyond the end of the fi le, an EOFException is thrown.
public final double readDouble() throws IOException
Reads a double value from the fi le and returns that value.
If an attempt is made to read beyond the end of the fi le, an EOFException is thrown.
public final float readFloat() throws IOException
Reads a float value from the fi le and returns that value.
If an attempt is made to read beyond the end of the fi le, an EOFException is thrown.
