## jcontrol.io
Class DataInputStream

    java.lang.Object
      jcontrol.io.InputStream
          jcontrol.io.DataInputStream

Direct Known Subclasses:
  GenericDataInputStream

    public abstract class DataInputStream

extends InputStream

A `DataInputStream` allows to read java basic data types from an `InputStream`. Additionally, the endianess of the contained data can be specified.

A DataInputStream can not be instantiated directly, instead an instance must be created through the static method `createDataInputStream( InputStream in, int endianess)`.

Field Summary
`static int` | `BIG_ENDIAN` Big endian mode.
`static int` | `LITTLE_ENDIAN` Little endian mode.

Constructor Summary
`DataInputStream()`

Method Summary
`static DataInputStream` | `createDataInputStream(InputStream in)` Creates a new DataInputStream with big endian data format.
`static DataInputStream` | `createDataInputStream(InputStream in, int endianess)` Creates a new DataInputStream.
`abstract boolean` | `readBoolean()` Reads a `boolean` value, represented by a byte value of `0` (false) of `1` (true), from the stream.
`abstract char` | `readChar()` Reads a `char` value from the stream.
`abstract double` | `readDouble()` Reads a `double` value from the stream.
`abstract float` | `readFloat()` Reads a `float` value from the stream.
`abstract int` | `readInt()` Reads an `int` value from the stream.
`abstract long` | `readLong()` Reads a `long` value from the stream.
`abstract short` | `readShort()` Reads a `short` value from the stream.

Constructor Detail

### DataInputStream

    public DataInputStream()

Method Detail

### createDataInputStream

    public static DataInputStream createDataInputStream(InputStream in,
                                                        int endianess)

  Creates a new DataInputStream.
  Note: No assumptions on the type of the returned DataInputStream is allowed, because it may vary over different platforms.

  Parameters:
    `in` - InputStream to use
    `endianess` - `BIG_ENDIAN` or `LITTLE_ENDIAN`
  Returns:
    DataInputStream

### createDataInputStream

    public static DataInputStream createDataInputStream(InputStream in)

  Creates a new DataInputStream with big endian data format.
  Note: No assumptions on the type of the returned DataInputStream is allowed, because it may vary over different platforms.

  Parameters:
    `in` - InputStream to use
  Returns:
    DataInputStream

### readBoolean

    public abstract boolean readBoolean()
                                 throws IOException

  Reads a `boolean` value, represented by a byte value of `0` (false) of `1` (true), from the stream.

  Returns:
    boolean value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readChar

    public abstract char readChar()
                           throws IOException

  Reads a `char` value from the stream.

  Returns:
    char value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readShort

    public abstract short readShort()
                             throws IOException

  Reads a `short` value from the stream.

  Returns:
    short value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readInt

    public abstract int readInt()
                         throws IOException

  Reads an `int` value from the stream.

  Returns:
    int value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readLong

    public abstract long readLong()
                           throws IOException

  Reads a `long` value from the stream.

  Returns:
    long value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readFloat

    public abstract float readFloat()
                             throws IOException

  Reads a `float` value from the stream.

  Returns:
    float value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed

### readDouble

    public abstract double readDouble()
                               throws IOException

  Reads a `double` value from the stream.

  Returns:
    double value
  Throws:
    `IOException` - occurs on I/O error or when the stream is closed
