Constructor Detail

FileInfoVectorResult

public FileInfoVectorResult(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

FileInfoVectorResult

public FileInfoVectorResult(long size)

Native array allocator. Access with Pointer.position(long).

FileInfoVectorResult

public FileInfoVectorResult()

Constructs a Result object that contains a non-OK status. This constructor is marked explicit to prevent attempts to return {} from a function with a return type of, for example, Result<std::vector<int>>. While return {} seems like it would return an empty vector, it will actually invoke the default constructor of Result.

FileInfoVectorResult

public FileInfoVectorResult(@Const @ByRef
                            Status status)

Constructs a Result object with the given non-OK Status object. All calls to ValueOrDie() on this object will abort. The given status must not be an OK status, otherwise this constructor will abort. This constructor is not declared explicit so that a function with a return type of Result<T> can return a Status object, and the status will be implicitly converted to the appropriate return type as a matter of convenience.

Parameters:

status - The non-OK Status object to initialize to.

FileInfoVectorResult

public FileInfoVectorResult(@StdVector
                            FileInfo value)

Constructs a Result object that contains value. The resulting object is considered to have an OK status. The wrapped element can be accessed with ValueOrDie(). This constructor is made implicit so that a function with a return type of Result<T> can return an object of type T, implicitly converting it to a Result<T> object.

Parameters:

value - The value to initialize to.

FileInfoVectorResult

public FileInfoVectorResult(@Const @ByRef
                            FileInfoVectorResult other)

Copy constructor. This constructor needs to be explicitly defined because the presence of the move-assignment operator deletes the default copy constructor. In such a scenario, since the deleted copy constructor has stricter binding rules than the templated copy constructor, the templated constructor cannot act as a copy constructor, and any attempt to copy-construct a Result object results in a compilation error.

Parameters:

other - The value to copy from.

Method Detail

position

public FileInfoVectorResult position(long position)

Overrides:

position in class Pointer

getPointer

public FileInfoVectorResult getPointer(long i)

Overrides:

getPointer in class Pointer

put

@ByRef
 @Name(value="operator =")
public FileInfoVectorResult put(@Const @ByRef
                                                                    FileInfoVectorResult other)

Copy-assignment operator.

Parameters:

other - The Result object to copy.

Equals

@Cast(value="bool")
public boolean Equals(@Const @ByRef
                                           FileInfoVectorResult other)

Compare to another Result.

ok

@Cast(value="bool")
public boolean ok()

Indicates whether the object contains a T value. Generally instead of accessing this directly you will want to use ASSIGN_OR_RAISE defined below.

Returns:

True if this Result object's status is OK (i.e. a call to ok() returns true). If this function returns true, then it is safe to access the wrapped element through a call to ValueOrDie().

status

@Const
 @ByRef
public Status status()

Gets the stored status object, or an OK status if a T value is stored. /** /** @return The stored non-OK status object, or an OK status if this object /** has a value.

ValueOrDie

@StdVector
public FileInfo ValueOrDie()

Gets a mutable reference to the stored T value. This method should only be called if this Result object's status is OK (i.e. a call to ok() returns true), otherwise this call will abort.

Returns:

The stored T value.

multiply

@StdVector
 @Name(value="operator *")
public FileInfo multiply()

ValueUnsafe

@StdVector
public FileInfo ValueUnsafe()

Cast the internally stored value to produce a new result or propagate the stored error.

MoveValueUnsafe

@StdVector
public FileInfo MoveValueUnsafe()
