it.unimi.dsi.fastutil.io .FastByteArrayInputStream

FastByteArrayInputStream
public class FastByteArrayInputStream extends MeasurableInputStream implements RepositionableStream(Code)
	Simple, fast and repositionable byte-array input stream. Warning: this class implements the correct semantics of FastByteArrayInputStream.read(byte[],int,int) as described in java.io.InputStream . The implementation given in java.io.ByteArrayInputStream is broken, but it will never be fixed because it's too late. author: Sebastiano Vigna

Field Summary
public byte[]	array The array backing the input stream.
public int	length The number of valid bytes in FastByteArrayInputStream.array starting from FastByteArrayInputStream.offset .
public int	offset The first valid entry.

Constructor Summary
public	FastByteArrayInputStream(byte[] array, int offset, int length) Creates a new array input stream using a given array fragment.
public	FastByteArrayInputStream(byte[] array) Creates a new array input stream using a given array.

Method Summary
public int	available()
public void	close() Closing a fast byte array input stream has no effect.
public long	length()
public void	mark(int dummy)
public boolean	markSupported()
public long	position()
public void	position(long newPosition)
public int	read()
public int	read(byte b, int offset, int length) Reads bytes from this byte-array input stream as specified in java.io.InputStream.read(byte[]intint) . Note that the implementation given in java.io.ByteArrayInputStream.read(byte[]intint) will return -1 on a zero-length read at EOF, contrarily to the specification.
public void	reset()
public long	skip(long n)

Field Detail

array
public byte[] array(Code)
	The array backing the input stream.

length
public int length(Code)
	The number of valid bytes in FastByteArrayInputStream.array starting from FastByteArrayInputStream.offset .

offset
public int offset(Code)
	The first valid entry.

Constructor Detail

FastByteArrayInputStream
public FastByteArrayInputStream(byte[] array, int offset, int length)(Code)
	Creates a new array input stream using a given array fragment. Parameters: array - the backing array. Parameters: offset - the first valid entry of the array. Parameters: length - the number of valid bytes.

FastByteArrayInputStream
public FastByteArrayInputStream(byte[] array)(Code)
	Creates a new array input stream using a given array. Parameters: array - the backing array.

Method Detail

read
public int read()(Code)

read
public int read(byte b, int offset, int length)(Code)
	Reads bytes from this byte-array input stream as specified in java.io.InputStream.read(byte[]intint) . Note that the implementation given in java.io.ByteArrayInputStream.read(byte[]intint) will return -1 on a zero-length read at EOF, contrarily to the specification. We won't.
