All Implemented Interfaces:

DataInput, DataOutput

public class RandomAccessArray

extends RandomAccessFile

An extension of RandomAccessFile providing random access into an array of bytes directly from memory. The implemention is very straightforward except for the copyArray methods, which replace readFully, and exist solely because readFully is declared final and thus cannot be overridden.

Constructor Summary

RandomAccessArray(String name, String mode)

Method Summary

void	close()
void	copyArray(byte[] b) This has the same functionality as RandomAccessFile's readFully.
void	copyArray(byte[] b, int off, int len)
long	getFilePointer()
long	length()
int	read() Reads a byte of data from the array.
int	read(byte[] b) Reads up to b.length bytes of data from the array.
int	read(byte[] b, int off, int len) Reads up to len bytes from the array.
void	seek(long pos) Sets the file pointer.
void	setLength(long newLength) Sets the array length.
void	setStream(byte[] b)
int	skipBytes(int n)
void	write(byte[] b)
void	write(byte[] b, int off, int len)
void	write(int b)

Constructor Detail

RandomAccessArray

public RandomAccessArray(String name,
                         String mode)
                  throws FileNotFoundException

Method Detail

setStream

public void setStream(byte[] b)

close

public void close()

getFilePointer

public long getFilePointer()

length

public long length()

seek

public void seek(long pos)

Sets the file pointer.

setLength

public void setLength(long newLength)

Sets the array length.

skipBytes

public int skipBytes(int n)

read

public int read()

Reads a byte of data from the array.

read

public int read(byte[] b)
         throws IOException

Reads up to b.length bytes of data from the array.

Throws:

IOException

read

public int read(byte[] b,
                int off,
                int len)
         throws IOException

Reads up to len bytes from the array.

Throws:

IOException

copyArray

public void copyArray(byte[] b)
               throws IOException

This has the same functionality as RandomAccessFile's readFully. The readFully signature is not used because it's final in RandomAccessFile.

Throws:

IOException

copyArray

public void copyArray(byte[] b,
                      int off,
                      int len)
               throws IOException

Throws:

IOException

write

public void write(int b)

write

public void write(byte[] b)

write

public void write(byte[] b,
                  int off,
                  int len)
