readBytes(IIOByteBuffer buf, int len) 从流中读取至多 len 个字节,并修改提供的 IIOByteBuffer 以指示可以找到数据的 byte 数组、偏移量和长度。 void ImageInputStreamImpl.readBytes(IIOByteBuffer buf, int len) char ImageInputStream.readChar() 与readUnsignedShort 等效,唯一的不同在于它的结果使用 ...
A URL connection can be used for input and/or output. Setting the doInput flag to true indicates that the application intends to read data from the URL connection. The default value of this field is true. See Also: getDoInput(), setDoInput(boolean) doOutput protected boolean doOutput This...

readAllBytes:读取 InputStream 中的所有剩余字节。 readNBytes:从 InputStream 中读取指定数量的字节到数组中。 transferTo:读取 InputStream 中的全部字节并写入到指定的 OutputStream 中。 下面是新方法的使用示例: 代码语言:javascript 代码运行次数:0 运行 AI代码解释 public class TestInputStream { private Input...
The JDK built-in implementation of the URL protocol handler for HTTP (HttpURLConnection) now has a default limit on the maximum response headers size that will be accepted from a remote party. The limit is set by default at 384kB (393216 bytes) and is computed as the cumulative size of ...
La implementación integrada de JDK del manejador del protocolo de URL para HTTP (HttpURLConnection) tiene ahora un límite por defecto para el tamaño máximo de las cabeceras de respuesta que se aceptará de una parte remota. El límite se ha definido en 384 kB (393 216 bytes) y se ...
