Options 类
每个基于 zlib 的类都有一个 options
对象。
不需要任何选项。
某些选项仅在压缩时相关,而被解压缩类忽略。
flush
<integer> 默认值:zlib.constants.Z_NO_FLUSH
finishFlush
<integer> 默认值:zlib.constants.Z_FINISH
chunkSize
<integer> 默认值:16 * 1024
windowBits
<integer>level
<integer> (仅压缩)memLevel
<integer> (仅压缩)strategy
<integer> (仅压缩)dictionary
<Buffer> | <TypedArray> | <DataView> | <ArrayBuffer> (仅 deflate/inflate,默认情况下为空字典)info
<boolean> (如果是true
,则返回具有buffer
和engine
的对象。)maxOutputLength
<integer> 使用便捷方法时限制输出大小。 默认值:buffer.kMaxLength
有关更多信息,请参阅 deflateInit2
和 inflateInit2
文档。
Each zlib-based class takes an options
object. No options are required.
Some options are only relevant when compressing and are ignored by the decompression classes.
flush
<integer> Default:zlib.constants.Z_NO_FLUSH
finishFlush
<integer> Default:zlib.constants.Z_FINISH
chunkSize
<integer> Default:16 * 1024
windowBits
<integer>level
<integer> (compression only)memLevel
<integer> (compression only)strategy
<integer> (compression only)dictionary
<Buffer> | <TypedArray> | <DataView> | <ArrayBuffer> (deflate/inflate only, empty dictionary by default)info
<boolean> (Iftrue
, returns an object withbuffer
andengine
.)maxOutputLength
<integer> Limits output size when using convenience methods. Default:buffer.kMaxLength
