Method Summary

Modifier and Type	Method and Description
public int	Returns: data length length() Return length data stored in the buffer
public int	Returns: the total number of bytes read into the buffer, or `-1` if there is no more data because the end of the stream has been reached. read(byte[] the buffer into which the data is read. b, int the start offset in array `b` at which the data is written. off, int the maximum number of bytes to read. len) Reads up to `len` bytes of data from this buffer into an array of bytes.
public int	Returns: one byte read() Reads one byte from this buffer.
public void	reset() Resets the buffer by clearing its state and stored content.

Method Detail

length	back to summary
public int length() Return length data stored in the buffer Returns:int data length

length

back to summary

public int length()

Return length data stored in the buffer

Returns:int: data length

read back to summary

read	back to summary
public int read(byte[] b, int off, int len) throws IOException Reads up to `len` bytes of data from this buffer into an array of bytes. The exact number of bytes read depends how many bytes are stored in the buffer. If `off` is negative, or `len` is negative, or `off+len` is greater than the length of the array `b`, this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns `-1` if the end of content stream has been reached. Parameters b:byte[] the buffer into which the data is read. off:int the start offset in array `b` at which the data is written. len:int the maximum number of bytes to read. Returns:int the total number of bytes read into the buffer, or `-1` if there is no more data because the end of the stream has been reached. Exceptions IOException: if an I/O error occurs.

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

Reads up to len bytes of data from this buffer into an array of bytes. The exact number of bytes read depends how many bytes are stored in the buffer.

If off is negative, or len is negative, or off+len is greater than the length of the array b, this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns -1 if the end of content stream has been reached.

Parameters

b:byte[]: the buffer into which the data is read.
off:int: the start offset in array b at which the data is written.
len:int: the maximum number of bytes to read.

Returns:int

the total number of bytes read into the buffer, or -1 if there is no more data because the end of the stream has been reached.

Exceptions

IOException:: if an I/O error occurs.

read back to summary

read	back to summary
public int read() throws IOException Reads one byte from this buffer. If the buffer is empty this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns `-1` if the end of content stream has been reached. Returns:int one byte

public int read() throws IOException

Reads one byte from this buffer. If the buffer is empty this method can throw a runtime exception. The exact type of runtime exception thrown by this method depends on implementation. This method returns -1 if the end of content stream has been reached.

Returns:int: one byte

reset	back to summary
public void reset() Resets the buffer by clearing its state and stored content.
