  • Field Summary

    Fields

    protected byte[]

    protected int

    The position within the pushback buffer from which the next byte will be read.

  • Constructor Summary

    Constructors

    Creates a PushbackInputStream with a 1-byte pushback buffer, and saves its argument, the input stream in, for later use.

    Creates a PushbackInputStream with a pushback buffer of the specified size, and saves its argument, the input stream in, for later use.

  • Method Summary

    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

    Tests if this input stream supports the mark and reset methods, which it does not.

    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.

    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.

    void

    unread(byte[] b)

    Pushes back an array of bytes by copying it to the front of the pushback buffer.

    void

    unread(byte[] b, int off, int len)

    Pushes back a portion of an array of bytes by copying it to the front of the pushback buffer.

    void

    unread(int b)

    Pushes back a byte by copying it to the front of the pushback buffer.

    Methods declared in class FilterInputStream

    read

    int

    Reads up to b.length bytes of data from this input stream into an array of bytes.

    Methods declared in class InputStream

    nullInputStream, readAllBytes, readNBytes, readNBytes, skipNBytes, transferTo

    Returns a new InputStream that reads no bytes.

    byte[]

    Reads all remaining bytes from the input stream.

    int

    Reads the requested number of bytes from the input stream into the given byte array.

    byte[]

    Reads up to a specified number of bytes from the input stream.

    void

    Skips over and discards exactly n bytes of data from this input stream.

    long

    Reads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read.

    Methods declared in class Object

    clone, equals, finalize, getClass, hashCode, notify, notifyAll, toString, wait, wait, wait

    Creates and returns a copy of this object.

    boolean

    Indicates whether some other object is "equal to" this one.

    protected void

    Deprecated, for removal: This API element is subject to removal in a future version.

    Returns the runtime class of this Object.

    int

    Returns a hash code value for this object.

    final void

    Wakes up a single thread that is waiting on this object's monitor.

    final void

    Wakes up all threads that are waiting on this object's monitor.

    Returns a string representation of the object.

    final void

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted.

    final void

    wait(long timeoutMillis)

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.

    final void

    wait(long timeoutMillis, int nanos)

    Causes the current thread to wait until it is awakened, typically by being notified or interrupted, or until a certain amount of real time has elapsed.
