Inherited Methods

From class java.util.zip.InflaterInputStream

From class java.io.FilterInputStream

int	available() Returns a int representing the number of bytes that are available before this FilterInputStream will block.
void	close() Close this FilterInputStream.
synchronized void	mark(int readlimit) Set a Mark position in this FilterInputStream.
boolean	markSupported() Returns a boolean indicating whether or not this FilterInputStream supports mark() and reset().
int	read(byte[] buffer, int offset, int count) Reads at most `count` bytes from this FilterInputStream and stores them in byte array `buffer` starting at `offset`.
int	read(byte[] buffer) Reads bytes from this FilterInputStream and stores them in byte array `buffer`.
int	read() Reads a single byte from this FilterInputStream and returns the result as an int.
synchronized void	reset() Reset this FilterInputStream to the last marked location.
long	skip(long count) Skips `count` number of bytes in this InputStream.

From class java.io.InputStream

int	available() Returns a int representing then number of bytes that are available before this InputStream will block.
void	close() Close the InputStream.
void	mark(int readlimit) Set a Mark position in this InputStream.
boolean	markSupported() Returns a boolean indicating whether or not this InputStream supports mark() and reset().
int	read(byte[] b, int offset, int length) Reads at most `length` bytes from the Stream and stores them in byte array `b` starting at `offset`.
int	read(byte[] b) Reads bytes from the Stream and stores them in byte array `b`.
abstract int	read() Reads a single byte from this InputStream and returns the result as an int.
synchronized void	reset() Reset this InputStream to the last marked location.
long	skip(long n) Skips `n` number of bytes in this InputStream.

From class java.lang.Object

Object	clone() Returns a new instance of the same class as the receiver, whose slots have been filled in with the values in the slots of the receiver.
boolean	equals(Object o) Compares the argument to the receiver, and returns true if they represent the same object using a class specific comparison.
void	finalize() Called by the virtual machine when there are no longer any (non-weak) references to the receiver.
final Class<? extends Object>	getClass() Returns the unique instance of java.lang.Class which represents the class of the receiver.
int	hashCode() Returns an integer hash code for the receiver.
final void	notify() Causes one thread which is `wait` ing on the receiver to be made ready to run.
final void	notifyAll() Causes all threads which are `wait` ing on the receiver to be made ready to run.
String	toString() Returns a string containing a concise, human-readable description of the receiver.
final void	wait(long time, int frac) Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final void	wait(long time) Causes the thread which sent this message to be made not ready to run either pending some change in the receiver (as indicated by `notify` or `notifyAll`) or the expiration of the timeout.
final void	wait() Causes the thread which sent this message to be made not ready to run pending some change in the receiver (as indicated by `notify` or `notifyAll`).
