- Method Detail
  - getPosition
```
int getPosition()
```
    Gets the current position in the stream.
    
    Returns:
    
    the current position
  - getSize
```
int getSize()
```
    Gets the current size of the stream in number of bytes.
    
    Returns:
    
    the size of the stream
  - truncateToPosition
```
void truncateToPosition(int newPosition)
```
    Truncates this stream to the new position. After this call, both size and position will equal the new position.
    
    Parameters:
    
    newPosition - the new position, which must be greater than or equal to 0 and less than the current size.
  - writeBytes
```
void writeBytes(byte[] bytes)
```
    Writes all the bytes in the byte array to the stream.
    
    Parameters:
    
    bytes - the non-null byte array
  - writeBytes
```
void writeBytes(byte[] bytes,
                int offset,
                int length)
```
    Writes length bytes from the byte array, starting at offset.
    
    Parameters:
    
    bytes - the non-null byte array
    
    offset - the offset to start writing from
    
    length - the number of bytes to write
  - writeByte
```
void writeByte(int value)
```
    Write a single byte to the stream. The byte to be written is the eight low-order bits of the specified value. The 24 high-order bits of the value are ignored.
    
    Parameters:
    
    value - the value
  - writeCString
```
void writeCString(String value)
```
    Writes a BSON CString to the stream.
    
    Parameters:
    
    value - the value
  - writeString
```
void writeString(String value)
```
    Writes a BSON String to the stream.
    
    Parameters:
    
    value - the value
  - writeDouble
```
void writeDouble(double value)
```
    Writes a BSON double to the stream.
    
    Parameters:
    
    value - the value
  - writeInt32
```
void writeInt32(int value)
```
    Writes a 32-bit BSON integer to the stream.
    
    Parameters:
    
    value - the value
  - writeInt32
```
void writeInt32(int position,
                int value)
```
    Writes a 32-bit BSON integer to the stream at the given position. This is useful for patching in the size of a document once the last byte of it has been encoded and its size it known.
    
    Parameters:
    
    position - the position to write the value, which must be greater than or equal to 0 and less than or equal to the current size
    
    value - the value
  - writeInt64
```
void writeInt64(long value)
```
    Writes a 64-bit BSON integer to the stream.
    
    Parameters:
    
    value - the value
  - writeObjectId
```
void writeObjectId(ObjectId value)
```
    Writes a BSON ObjectId to the stream.
    
    Parameters:
    
    value - the value
  - close
```
void close()
```
    Specified by:
    
    close in interface AutoCloseable
