本文整理了Java中javax.enterprise.util.TypeLiteral类的一些代码示例，展示了TypeLiteral类的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。TypeLiteral类的具体详情如下：
包路径：javax.enterprise.util.TypeLiteral
类名称：TypeLiteral

TypeLiteral介绍

[英]Supports inline instantiation of objects that represent parameterized types with actual type parameters.

An object that represents any parameterized type may be obtained by subclassing TypeLiteral.

TypeLiteral<List<String>> stringListType = new TypeLiteral<List<String>>() { 
};

[中]支持使用实际类型参数内联实例化表示参数化类型的对象。
可以通过子类化TypeLiteral来获得表示任何参数化类型的对象。

TypeLiteral<List<String>> stringListType = new TypeLiteral<List<String>>() { 
};

代码示例

代码示例来源：origin: javax.enterprise/cdi-api

@Override
public boolean equals(Object obj) {
  if (obj instanceof TypeLiteral<?>) {
    TypeLiteral<?> that = (TypeLiteral<?>) obj;
    return this.getType().equals(that.getType());
  }
  return false;
}

代码示例来源：origin: javax.enterprise/cdi-api

/**
 * @return the actual type represented by this object
 */
public final Type getType() {
  if (actualType == null) {
    Class<?> typeLiteralSubclass = getTypeLiteralSubclass(this.getClass());
    if (typeLiteralSubclass == null) {
      throw new RuntimeException(getClass() + " is not a subclass of TypeLiteral");
    }
    actualType = getTypeParameter(typeLiteralSubclass);
    if (actualType == null) {
      throw new RuntimeException(getClass() + " does not specify the type parameter T of TypeLiteral<T>");
    }
  }
  return actualType;
}
