Constructor Detail

ResizableUniqueResult

public ResizableUniqueResult(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

ResizableUniqueResult

public ResizableUniqueResult(long size)

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

ResizableUniqueResult

public ResizableUniqueResult()

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.

ResizableUniqueResult

public ResizableUniqueResult(@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.

ResizableUniqueResult

public ResizableUniqueResult(@UniquePtr
                             ResizableBuffer 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.

Method Detail

position

public ResizableUniqueResult position(long position)

Overrides:

position in class Pointer

getPointer

public ResizableUniqueResult getPointer(long i)

Overrides:

getPointer in class Pointer

Equals

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

Compare to another Result.

ok

@Cast(value="const 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

@UniquePtr
public ResizableBuffer 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

@UniquePtr
 @Name(value="operator *")
public ResizableBuffer multiply()

access

@UniquePtr
 @Name(value="operator ->")
public ResizableBuffer access()

ValueUnsafe

@UniquePtr
public ResizableBuffer ValueUnsafe()

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

MoveValueUnsafe

@UniquePtr
public ResizableBuffer MoveValueUnsafe()
