Method Summary
intReturns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.
voidclose()Closes this input stream and releases any system resources associated with the stream.
voidmark(int readlimit) Marks the current position in this input stream.
booleanTests if this input stream supports the
markandresetmethods.Returns a new
InputStreamthat reads no bytes.abstract intread()Reads the next byte of data from the input stream.
intread(byte[] b) Reads some number of bytes from the input stream and stores them into the buffer array
b.intread(byte[] b, int off, int len) Reads up to
lenbytes of data from the input stream into an array of bytes.byte[]Reads all remaining bytes from the input stream.
intreadNBytes(byte[] b, int off, int len) Reads the requested number of bytes from the input stream into the given byte array.
byte[]readNBytes(int len) Reads up to a specified number of bytes from the input stream.
voidreset()Repositions this stream to the position at the time the
markmethod was last called on this input stream.longskip(long n) Skips over and discards
nbytes of data from this input stream.voidskipNBytes(long n) Skips over and discards exactly
nbytes of data from this input stream.longReads all bytes from this input stream and writes the bytes to the given output stream in the order that they are read.
