Constructor Details

SyncInputStream

public SyncInputStream(InputStream in,
 long length,
 boolean isAsync,
 boolean isIgnoreEOFError)

构造
如果isAsync为true，则直接持有原有流，false，则将流中内容，按照给定length读到ByteArrayInputStream中备用

Parameters:

in - 数据流

length - 限定长度，-1表示未知长度

isAsync - 是否异步

isIgnoreEOFError - 是否忽略EOF错误，在Http协议中，对于Transfer-Encoding: Chunked在正常情况下末尾会写入一个Length为0的的chunk标识完整结束
如果服务端未遵循这个规范或响应没有正常结束，会报EOF异常，此选项用于是否忽略这个异常。

Method Details

sync

public void sync()

同步数据到内存

readBytes

public byte[] readBytes()

读取流中所有bytes

Returns:

bytes

copyTo

public long copyTo(OutputStream out,
 Progress streamProgress)

将流的内容拷贝到输出流

Parameters:

out - 输出流

streamProgress - 进度条

Returns:

拷贝长度
