Methods

Accept(IArrowArrayVisitor)

public override void Accept(IArrowArrayVisitor visitor)

Parameters

visitor IArrowArrayVisitor

GetBytes(int)

Get the collection of bytes, as a read-only span, at a given index in the array.

public ReadOnlySpan<byte> GetBytes(int index)

Parameters

index int

Index at which to get bytes.

Returns

ReadOnlySpan<byte>

Returns a ReadOnlySpan<T> object.

Remarks

Note that this method cannot reliably identify null values, which are indistinguishable from empty byte collection values when seen in the context of this method's return type of ReadOnlySpan<T>. Use the IsNull(int) method or the GetBytes(int, out bool) overload instead to reliably determine null values.

Exceptions

ArgumentOutOfRangeException

If the index is negative or beyond the length of the array.

GetBytes(int, out bool)

Get the collection of bytes, as a read-only span, at a given index in the array.

public ReadOnlySpan<byte> GetBytes(int index, out bool isNull)

Parameters

index int

Index at which to get bytes.

isNull bool

Set to true if the value at the given index is null.

Returns

ReadOnlySpan<byte>

Returns a ReadOnlySpan<T> object.

Exceptions

ArgumentOutOfRangeException

If the index is negative or beyond the length of the array.

GetValueLength(int)

public int GetValueLength(int index)

Parameters

index int

Returns

int
