public class DataInputStream

The input stream.

Creates a DataInputStream and saves its argument, the input stream in, for later use. in - the input stream.

Returns the number of bytes that can be read from this input stream without blocking. This method simply performs in.available() and returns the result.

Closes this input stream and releases any system resources associated with the stream. This method simply performs in.close().

Marks the current position in this input stream. A subsequent call to the reset method repositions this stream at the last marked position so that subsequent reads re-read the same bytes. The readlimit argument tells this input stream to allow that many bytes to be read before the mark position gets invalidated. This method simply performs in.mark(readlimit).

Tests if this input stream supports the mark and reset methods. This method simply performs in.markSupported().

Reads the next byte of data from this input stream. The value byte is returned as an int in the range 0 to 255. If no byte is available because the end of the stream has been reached, the value -1 is returned. This method blocks until input data is available, the end of the stream is detected, or an exception is thrown. This method simply performs in.read() and returns the result.

See the general contract of the read method of DataInput. Bytes for this operation are read from the contained input stream.

Reads up to len bytes of data from this input stream into an array of bytes. This method blocks until some input is available. This method simply performs in.read(b, off, len) and returns the result.

See the general contract of the readBoolean method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readByte method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readChar method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readDouble method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readFloat method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readFully method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readFully method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readInt method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readLong method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readShort method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readUnsignedByte method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readUnsignedShort method of DataInput. Bytes for this operation are read from the contained input stream.

See the general contract of the readUTF method of DataInput. Bytes for this operation are read from the contained input stream.

Reads from the stream in a representation of a Unicode character string encoded in Java modified UTF-8 format; this string of characters is then returned as a String. The details of the modified UTF-8 representation are exactly the same as for the readUTF method of DataInput.

Repositions this stream to the position at the time the mark method was last called on this input stream. This method simply performs in.reset(). Stream marks are intended to be used in situations where you need to read ahead a little to see what’s in the stream. Often this is most easily done by invoking some general parser. If the stream is of the type handled by the parse, it just chugs along happily. If the stream is not of that type, the parser should toss an exception when it fails. If this happens within readlimit bytes, it allows the outer code to reset the stream and try another parser.

Skips over and discards n bytes of data from the input stream. The skip method may, for a variety of reasons, end up skipping over some smaller number of bytes, possibly 0. The actual number of bytes skipped is returned. This method simply performs in.skip(n).

See the general contract of the skipBytes method of DataInput. Bytes for this operation are read from the contained input stream.
