用Builder生成泛型，generics type builder

TypeBuilder

一个用于生成泛型的简易Builder

Example for List<String>

Type type = TypeBuilder
        .newInstance(List.class)
        .addTypeParam(String.class)
        .build();

Example for List<? super String>

Type type = TypeBuilder
        .newInstance(List.class)
        .addTypeParamSuper(String.class)
        .build();

Example for List<? extends CharSequence>

Type type = TypeBuilder
        .newInstance(List.class)
        .addTypeParamExtends(CharSequence.class)
        .build();

Example for Map<String, String[]>

Type type = TypeBuilder
        .newInstance(HashMap.class)
        .addTypeParam(String.class)
        .addTypeParam(String[].class)
        .build();

Example for Map<String, List<String>>

Type type = TypeBuilder
        .newInstance(Map.class)
        .addTypeParam(String.class)
        .beginSubType(List.class) //开始 List<String> 部分
        .addTypeParam(String.class) //设置List的泛型值
        .endSubType() //结束 List<String> 部分
        .build();

有什么用

当你无法通过子类去获取泛型时，不用写一长串的嵌套或去实现部分Type接口。
