FastByteArrayOutputStream

public FastByteArrayOutputStream()

Create a new FastByteArrayOutputStream with the default initial capacity of 256 bytes.

FastByteArrayOutputStream

public FastByteArrayOutputStream(int initialBlockSize)

Create a new FastByteArrayOutputStream with the specified initial capacity.

参数:

initialBlockSize - the initial buffer size in bytes

方法详细资料

write

public void write(int datum)
           throws IOException

指定者:

write 在类中 OutputStream

抛出:

IOException

write

public void write(byte[] data,
 int offset,
 int length)
           throws IOException

覆盖:

write 在类中 OutputStream

抛出:

IOException

close

public void close()

指定者:

close 在接口中 AutoCloseable

指定者:

close 在接口中 Closeable

覆盖:

close 在类中 OutputStream

toString

public String toString()

覆盖:

toString 在类中 Object

size

public int size()

toByteArrayUnsafe

public byte[] toByteArrayUnsafe()

toByteArray

public byte[] toByteArray()

reset

public void reset()

Reset the contents of this FastByteArrayOutputStream.

All currently accumulated output in the output stream is discarded. The output stream can be used again.

getInputStream

public InputStream getInputStream()

writeTo

public void writeTo(OutputStream out)
             throws IOException

Write the buffers content to the given OutputStream.

参数:

out - the OutputStream to write to

抛出:

IOException

resize

public void resize(int targetCapacity)
