ResizableByteArrayOutputStream (Spring Framework 4.3.30.RELEASE API)

java.lang.Object
- java.io.OutputStream
- - java.io.ByteArrayOutputStream
  - - org.springframework.util.ResizableByteArrayOutputStream

所有已实现的接口:
Closeable, Flushable, AutoCloseable
```
public class ResizableByteArrayOutputStream
extends ByteArrayOutputStream
```
An extension of ByteArrayOutputStream that:
- has public grow(int) and resize(int) methods to get more control over the size of the internal buffer
- has a higher initial capacity (256) by default
As of 4.2, this class has been superseded by FastByteArrayOutputStream for Spring's internal use where no assignability to ByteArrayOutputStream is needed (since FastByteArrayOutputStream is more efficient with buffer resize management but doesn't extend the standard ByteArrayOutputStream).
从以下版本开始:
4.0.3

  - ResizableByteArrayOutputStream
```
public ResizableByteArrayOutputStream()
```
    Create a new ResizableByteArrayOutputStream with the default initial capacity of 256 bytes.
  - ResizableByteArrayOutputStream
```
public ResizableByteArrayOutputStream(int initialCapacity)
```
    Create a new ResizableByteArrayOutputStream with the specified initial capacity.
    参数:
    initialCapacity - the initial buffer size in bytes

  - resize
```
public void resize(int targetCapacity)
```
    Resize the internal buffer size to a specified capacity.
    参数:
    targetCapacity - the desired size of the buffer
    抛出:
    IllegalArgumentException - if the given capacity is smaller than the actual size of the content stored in the buffer already

```
public void grow(int additionalCapacity)
```
    Grow the internal buffer size.
    参数:
    additionalCapacity - the number of bytes to add to the current buffer size
