Constructor Detail

ScalarKernelResult

public ScalarKernelResult(Pointer p)

Pointer cast constructor. Invokes Pointer(Pointer).

ScalarKernelResult

public ScalarKernelResult(long size)

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

ScalarKernelResult

public ScalarKernelResult()

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.

ScalarKernelResult

public ScalarKernelResult(@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.

ScalarKernelResult

public ScalarKernelResult(ScalarKernel 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.

ScalarKernelResult

public ScalarKernelResult(@Cast(value="const arrow::Result<arrow::compute::ScalarKernel*>*") @ByRef
                          ScalarKernelResult 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 ScalarKernelResult position(long position)

Overrides:

position in class Pointer

getPointer

public ScalarKernelResult getPointer(long i)

Overrides:

getPointer in class Pointer

put

@Cast(value="arrow::Result<arrow::compute::ScalarKernel*>*")
 @ByRef
 @Name(value="operator =")
 @NoException(value=true)
public ScalarKernelResult put(@Cast(value="const arrow::Result<arrow::compute::ScalarKernel*>*") @ByRef
                                                                                                                                                            ScalarKernelResult other)

Copy-assignment operator.

Parameters:

other - The Result object to copy.

Equals

@Cast(value="bool")
public boolean Equals(@Cast(value="const arrow::Result<arrow::compute::ScalarKernel*>*") @ByRef
                                           ScalarKernelResult 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

@ByPtrRef
public ScalarKernel 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

@ByPtrRef
 @Name(value="operator *")
public ScalarKernel multiply()

access

@Cast(value="arrow::compute::ScalarKernel**")
 @Name(value="operator ->")
public PointerPointer access()

ValueUnsafe

@ByPtrRef
public ScalarKernel ValueUnsafe()

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

MoveValueUnsafe

public ScalarKernel MoveValueUnsafe()
