Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`boolean`	`equals(Object other)`	Note that StatusOr containing statuses, the equality comparision is delegated to `Status.equals(java.lang.Object)` which just does a reference equality check because equality on Statuses is not well defined.
`static <T> StatusOr<T>`	`fromStatus(Status status)`	Construct from a non-Ok status.
`static <T> StatusOr<T>`	`fromValue(T value)`	Construct from a value.
`Status`	`getStatus()`	Returns the status.
`T`	`getValue()`	Returns the value if set or throws exception if there is no value set.
`int`	`hashCode()`
`boolean`	`hasValue()`	Returns whether there is a value.
`String`	`toString()`

- Method Detail
  - fromValue
```
public static <T> StatusOr<T> fromValue(@Nullable
                                        T value)
```
    Construct from a value.
  - fromStatus
```
public static <T> StatusOr<T> fromStatus(Status status)
```
    Construct from a non-Ok status.
  - hasValue
```
public boolean hasValue()
```
    Returns whether there is a value.
  - getValue
```
@Nullable
public T getValue()
```
    Returns the value if set or throws exception if there is no value set. This method is meant to be called after checking the return value of hasValue() first.
  - getStatus
```
public Status getStatus()
```
    Returns the status. If there is a value (which can be null), returns OK.
  - equals
```
public boolean equals(Object other)
```
    Note that StatusOr containing statuses, the equality comparision is delegated to Status.equals(java.lang.Object) which just does a reference equality check because equality on Statuses is not well defined. Instead, do comparison based on their Code with Status.getCode(). The description and cause of the Status are unlikely to be stable, and additional fields may be added to Status in the future.
