表达式执行引擎包
引擎必须实现AST包 github.com/zhuxiujia/GoMybatis/ast 下 ast.ExpressionEngine
type ExpressionEngine interface {
//引擎名称
Name() string
//编译一个表达式
//参数：lexerArg 表达式内容
//返回：interface{} 编译结果,error 错误
Lexer(lexerArg string) (interface{}, error)
//执行一个表达式
//参数：lexerResult=编译结果，arg=参数
//返回：执行结果，错误
Eval(lexerResult interface{}, arg interface{}, operation int) (interface{}, error)
LexerAndEval(lexerArg string,arg interface{}) (interface{}, error)
}
