+# TypeBuilder
+
+一个用于生成泛型的简易Builder
+
+#### Example for List<String>
+```java
+Type type = TypeBuilder
+ .newInstance(List.class)
+ .addTypeParam(String.class)
+ .build();
+```
+
+#### Example for List<? super String>
+```java
+Type type = TypeBuilder
+ .newInstance(List.class)
+ .addTypeParamSuper(String.class)
+ .build();
+```
+
+#### Example for List<? extends CharSequence>
+```java
+Type type = TypeBuilder
+ .newInstance(List.class)
+ .addTypeParamExtends(CharSequence.class)
+ .build();
+```
+
+#### Example for Map<String, String[]>
+```java
+Type type = TypeBuilder
+ .newInstance(HashMap.class)
+ .addTypeParam(String.class)
+ .addTypeParam(String[].class)
+ .build();
+```
+
+#### Example for Map<String, List<String>>
+```java
+Type type = TypeBuilder
+ .newInstance(Map.class)
+ .addTypeParam(String.class)
+ .beginSubType(List.class) //开始 List 部分
+ .addTypeParam(String.class) //设置List的泛型值
+ .endSubType() //结束 List 部分
+ .build();
+```
+
+#### 有什么用
+**并没有什么卵用**，可能唯一个用途就是当你无法通过子类去获取泛型时，不用写一长串的嵌套。
