Class BinaryOutputFile

java.lang.Object

BasicIO.BinaryOutputFile

public class BinaryOutputFile
extends java.lang.Object

BinaryOutputFile writes binary data to a file. The specified data type is written to a file in its binary representation. If an Object is being written, then serialization will occur. If the data can not be written to the file, either due to lack of space, or the file can not be found, then the successful method will return false.

Constructor Detail

BinaryOutputFile

public BinaryOutputFile()

Constructs an BinaryOutputFile, prompting the user via Dialog Box for a file to write to.

BinaryOutputFile

public BinaryOutputFile(java.lang.String filename)

Constructs an BinaryOutputFile and tries to open a file with the path provided in the String.

Parameters:

filename - the name of the file to write to

BinaryOutputFile

public BinaryOutputFile(java.io.File file)

Constructs an BinaryOutputFile using the file provided.

Parameters:

file - the file to write to

Method Detail

getFile

public java.io.File getFile()

Returns the file being used

Returns:

the file being used.

successful

public boolean successful()

Indicates whether or not the previous operation was successful. If it was a write operation, failure indicates the write was not possible (usually some I/O error). If it was a close operation, failure indicates inability to close the stream. The stream may subsequently be inaccessable.

Returns:

boolean: whether last operation was successful

close

public void close()

Closes the file.

writeByte

public void writeByte(byte b)

Writes a byte to the file

Parameters:

b - a byte to be written

writeChar

public void writeChar(char c)

Writes a char to the file

Parameters:

c - char to be written

writeDouble

public void writeDouble(double d)

Writes a double to the file

Parameters:

d - a double to be written

writeFloat

public void writeFloat(float f)

Writes a float to the file

Parameters:

f - is written to be written

writeInt

public void writeInt(int i)

Writes an int to the file

Parameters:

i - is written to be written

writeShort

public void writeShort(short s)

Writes a short to the file

Parameters:

s - is written to be written

writeLong

public void writeLong(long l)

Writes a long to the file

Parameters:

l - is written to be written

writeString

public void writeString(java.lang.String s)

Writes a String to the file

Parameters:

s - is written to be written

writeBoolean

public void writeBoolean(boolean b)

Writes a boolean to the file

Parameters:

b - is written to be written

writeObject

public void writeObject(java.lang.Object o)

Writes an Object to the file using serialization.

Parameters:

o - is written to be written
