TypeToken.where介绍

[英]Returns a new TypeToken where type variables represented by typeParam are substituted by typeArg. For example, it can be used to construct Map for any K and V type:

static  TypeToken> mapOf(return new TypeToken>() {} 
.where(new TypeParameter() {}, keyType) 
.where(new TypeParameter() {}, valueType); 
} 
}

[中]返回一个新的TypeToken，其中typeParam表示的类型变量被typeArg替换。例如，它可以用于为任何K和V类型构建映射：

static  TypeToken> mapOf(return new TypeToken>() {} 
.where(new TypeParameter() {}, keyType) 
.where(new TypeParameter() {}, valueType); 
} 
}
