-UTIL接口用于字符编码TextEncoder、解码TextDecoder、帮助函数HelpFunction、基于Base64的字节编码encode和解码decode、有理数RationalNumber。TextEncoder表示一个文本编码器，接受字符串作为输入，以UTF-8格式进行编码，输出UTF-8字节流。TextDecoder接口表示一个文本解码器，解码器将字节流作为输入，输出stirng字符串。HelpFunction主要是对函数做callback化、promise化以及对错误码进行编写输出，及类字符串的格式化输出。encode接口使用Base64编码方案将指定u8数组中的所有字节编码到新分配的u8数组中或者使用Base64编码方案将指定的字节数组编码为String。decode接口使用Base64编码方案将Base64编码的字符串或输入u8数组解码为新分配的u8数组。RationalNumber有理数主要是对有理数进行比较，获取分子分母等方法。LruBuffer该算法在缓存空间不够的时候，将近期最少使用的数据替换为新数据。该算法源自这样一种访问资源的需求：近期访问的数据，可能在不久的将来会再次访问。于是最少访问的数据就是价值最小的，是最应该踢出缓存空间的数据。Scope接口用于描述一个字段的有效范围。 Scope实例的构造函数用于创建具有指定下限和上限的对象，并要求这些对象必须具有可比性。 -## 目录 - -``` -base/compileruntime/js_util_module/ -├── Class:TextEncoder # TextEncoder类 -│ ├── new TextEncoder() # 创建TextEncoder对象 -│ ├── encode() #

+UTIL接口用于字符编码TextEncoder、解码TextDecoder、帮助函数HelpFunction、基于Base64的字节编码encode和解码decode、有理数RationalNumber。TextEncoder表示一个文本编码器，接受字符串作为输入，以UTF-8格式进行编码，输出UTF-8字节流。TextDecoder接口表示一个文本解码器，解码器将字节流作为输入，输出stirng字符串。HelpFunction主要是对函数做callback化、promise化以及对错误码进行编写输出，及类字符串的格式化输出。encode接口使用Base64编码方案将指定u8数组中的所有字节编码到新分配的u8数组中或者使用Base64编码方案将指定的字节数组编码为String。decode接口使用Base64编码方案将Base64编码的字符串或输入u8数组解码为新分配的u8数组。RationalNumber有理数主要是对有理数进行比较，获取分子分母等方法。LruBuffer该算法在缓存空间不够的时候，将近期最少使用的数据替换为新数据。该算法源自这样一种访问资源的需求：近期访问的数据，可能在不久的将来会再次访问。于是最少访问的数据就是价值最小的，是最应该踢出缓存空间的数据。Scope接口用于描述一个字段的有效范围。 Scope实例的构造函数用于创建具有指定下限和上限的对象，并要求这些对象必须具有可比性。 +## 目录 + +``` +base/compileruntime/js_util_module/ +├── Class:TextEncoder # TextEncoder类 +│ ├── new TextEncoder() # 创建TextEncoder对象 +│ ├── encode() #
