Method Detail

isBuffering

public boolean isBuffering()

设置是否将所有信息保存在内存中。

Specified by:

isBuffering in interface BufferedWebContext

Returns:

如果是，则返回true

setBuffering

public void setBuffering(boolean buffering)

设置buffer模式，如果设置成true，表示将所有信息保存在内存中，否则直接输出到原始response中。

此方法必须在getOutputStream和getWriter方法之前执行，否则将抛出 IllegalStateException。

Specified by:

setBuffering in interface BufferedWebContext

Parameters:

buffering - 是否buffer内容

Throws:

IllegalStateException - getOutputStream或 getWriter方法已经被执行

pushBuffer

public void pushBuffer()

创建新的buffer，保存老的buffer。

Specified by:

pushBuffer in interface BufferedWebContext

Throws:

IllegalStateException - 如果不在buffer模式，或getWriter及 getOutputStream方法从未被调用

popByteBuffer

public ByteArray popByteBuffer()

弹出最近的buffer，如果堆栈中只有一个buffer，则弹出后再创建一个新的。

Specified by:

popByteBuffer in interface BufferedWebContext

Returns:

最近的buffer内容

Throws:

IllegalStateException - 如果不在buffer模式，或getWriter 方法曾被调用，或 getOutputStream方法从未被调用

popCharBuffer

public String popCharBuffer()

弹出最近的buffer，如果堆栈中只有一个buffer，则弹出后再创建一个新的。

Specified by:

popCharBuffer in interface BufferedWebContext

Returns:

最近的buffer内容

Throws:

IllegalStateException - 如果不在buffer模式，或getOutputStream 方法曾被调用，或getWriter方法从未被调用

getBufferedResponse

public BufferedResponseImpl getBufferedResponse()

取得BufferedRunDataResponse实例。

Returns:

BufferedRunDataResponse实例

peekByteBuffer

public ByteArray peekByteBuffer()

Description copied from interface: BufferedWebContext

返回最上层的ByteArray

Specified by:

peekByteBuffer in interface BufferedWebContext

Returns:

最近的buffer内容

peekCharBuffer

public String peekCharBuffer()

Description copied from interface: BufferedWebContext

返回最上层的buffer

Specified by:

peekCharBuffer in interface BufferedWebContext

Returns:

最近的buffer内容
