- Method Detail
  - getPosition
```
int getPosition()
```
    Gets the current position in the stream
    
    Returns:
    
    the current position
  - readByte
```
byte readByte()
```
    Reads a single byte from the stream
    
    Returns:
    
    the byte value
  - readBytes
```
void readBytes(byte[] bytes)
```
    Reads the specified number of bytes into the given byte array. This is equivalent to to readBytes(bytes, 0, bytes.length).
    
    Parameters:
    
    bytes - the byte array to write into
  - readBytes
```
void readBytes(byte[] bytes,
               int offset,
               int length)
```
    Reads the specified number of bytes into the given byte array starting at the specified offset.
    
    Parameters:
    
    bytes - the byte array to write into
    
    offset - the offset to start writing
    
    length - the number of bytes to write
  - readInt64
```
long readInt64()
```
    Reads a BSON Int64 value from the stream.
    
    Returns:
    
    the Int64 value
  - readDouble
```
double readDouble()
```
    Reads a BSON Double value from the stream.
    
    Returns:
    
    the double value
  - readInt32
```
int readInt32()
```
    Reads a BSON Int32 value from the stream.
    
    Returns:
    
    the Int32 value
  - readString
```
String readString()
```
    Reads a BSON String value from the stream.
    
    Returns:
    
    the string
  - readObjectId
```
ObjectId readObjectId()
```
    Reads a BSON ObjectId value from the stream.
    
    Returns:
    
    the ObjectId
  - readCString
```
String readCString()
```
    Reads a BSON CString value from the stream.
    
    Returns:
    
    the CString
  - skipCString
```
void skipCString()
```
    Skips a BSON CString value from the stream.
  - skip
```
void skip(int numBytes)
```
    Skips the specified number of bytes in the stream.
    
    Parameters:
    
    numBytes - the number of bytes to skip
  - mark
```
void mark(int readLimit)
```
    Marks the current position in the stream. This method obeys the contract as specified in the same method in InputStream.
    
    Parameters:
    
    readLimit - the maximum limit of bytes that can be read before the mark position becomes invalid
  - reset
```
void reset()
```
    Resets the stream to the current mark. This method obeys the contract as specified in the same method in InputStream.
  - hasRemaining
```
boolean hasRemaining()
```
    Returns true if there are more bytes left in the stream.
    
    Returns:
    
    true if there are more bytes left in the stream.
  - close
```
void close()
```
    Specified by:
    
    close in interface AutoCloseable
    
    Specified by:
    
    close in interface Closeable
