InflaterInputStream

Summary

Constants
`int`	`GZIP_MAGIC` GZIP header magic number.

Fields
`protected CRC32`	`crc` CRC-32 for uncompressed data.
`protected boolean`	`eos` Indicates end of input stream.

Inherited fields

From class java.util.zip.InflaterInputStream

`protected byte[]`	`buf` Input buffer for decompression.
`protected boolean`	`closed` This field is deprecated. This field will be removed from a future version of Android and should not be used. Subclasses that access this field need to be modified to keep track of their own closed state by overriding close().
`protected Inflater`	`inf` Decompressor for this stream.
`protected int`	`len` Length of input buffer.

From class java.io.FilterInputStream


    protected
    
    
    InputStream

in

The input stream to be filtered.

Public constructors
`GZIPInputStream(InputStream in, int size)` Creates a new input stream with the specified buffer size.
`GZIPInputStream(InputStream in)` Creates a new input stream with a default buffer size.

Public methods
`void`	`close()` Closes this input stream and releases any system resources associated with the stream.
`int`	`read(byte[] buf, int off, int len)` Reads uncompressed data into an array of bytes.

Inherited methods

From class


        
          java.util.zip.InflaterInputStream

`int`	`available()` Returns 0 after EOF has been reached, otherwise always return 1.
`void`	`close()` Closes this input stream and releases any system resources associated with the stream.
`void`	`fill()` Fills input buffer with more data to decompress.
`void`	`mark(int readlimit)` Marks the current position in this input stream.
`boolean`	`markSupported()` Tests if this input stream supports the `mark` and `reset` methods.
`int`	`read()` Reads a byte of uncompressed data.
`int`	`read(byte[] b, int off, int len)` Reads uncompressed data into an array of bytes.
`void`	`reset()` Repositions this stream to the position at the time the `mark` method was last called on this input stream.
`long`	`skip(long n)` Skips specified number of bytes of uncompressed data.

From class


        
          java.io.FilterInputStream

`int`	`available()` Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
`void`	`close()` Closes this input stream and releases any system resources associated with the stream.
`void`	`mark(int readlimit)` Marks the current position in this input stream.
`boolean`	`markSupported()` Tests if this input stream supports the `mark` and `reset` methods.
`int`	`read()` Reads the next byte of data from this input stream.
`int`	`read(byte[] b, int off, int len)` Reads up to `len` bytes of data from this input stream into an array of bytes.
`int`	`read(byte[] b)` Reads up to `byte.length` bytes of data from this input stream into an array of bytes.
`void`	`reset()` Repositions this stream to the position at the time the `mark` method was last called on this input stream.
`long`	`skip(long n)` Skips over and discards `n` bytes of data from the input stream.

From class


        
          java.io.InputStream

`int`	`available()` Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking by the next invocation of a method for this input stream.
`void`	`close()` Closes this input stream and releases any system resources associated with the stream.
`void`	`mark(int readlimit)` Marks the current position in this input stream.
`boolean`	`markSupported()` Tests if this input stream supports the `mark` and `reset` methods.
`abstract int`	`read()` Reads the next byte of data from the input stream.
`int`	`read(byte[] b, int off, int len)` Reads up to `len` bytes of data from the input stream into an array of bytes.
`int`	`read(byte[] b)` Reads some number of bytes from the input stream and stores them into the buffer array `b`.
`void`	`reset()` Repositions this stream to the position at the time the `mark` method was last called on this input stream.
`long`	`skip(long n)` Skips over and discards `n` bytes of data from this input stream.

From class


        
          java.lang.Object

`Object`	`clone()` Creates and returns a copy of this object.
`boolean`	`equals(Object obj)` Indicates whether some other object is "equal to" this one.
`void`	`finalize()` Called by the garbage collector on an object when garbage collection determines that there are no more references to the object.
`final Class<?>`	`getClass()` Returns the runtime class of this `Object`.
`int`	`hashCode()` Returns a hash code value for the object.
`final void`	`notify()` Wakes up a single thread that is waiting on this object's monitor.
`final void`	`notifyAll()` Wakes up all threads that are waiting on this object's monitor.
`String`	`toString()` Returns a string representation of the object.
`final void`	`wait(long timeout, int nanos)` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed.
`final void`	`wait(long timeout)` Causes the current thread to wait until either another thread invokes the `notify()` method or the `notifyAll()` method for this object, or a specified amount of time has elapsed.
`final void`	`wait()` Causes the current thread to wait until another thread invokes the `notify()` method or the `notifyAll()` method for this object.
