Methods

Append(byte)

Appends a value, consisting of a single byte, to the array.

public TBuilder Append(byte value)

Parameters

value byte

Byte value to append.

Returns

TBuilder

Returns the builder (for fluent-style composition).

Append(ReadOnlySpan<byte>)

Append a value, consisting of a span of bytes, to the array.

public TBuilder Append(ReadOnlySpan<byte> span)

Parameters

span ReadOnlySpan<byte>

Span of bytes to add.

Returns

TBuilder

Returns the builder (for fluent-style composition).

Remarks

Note that a single value is added, which consists of arbitrarily many bytes. If multiple values are to be added, use the AppendRange(IEnumerable<byte>) method.

AppendNull()

Append a single null value to the array.

public TBuilder AppendNull()

Returns

TBuilder

Returns the builder (for fluent-style composition).

AppendRange(IEnumerable<byte[]>)

Append an enumerable collection of values to the array.

public TBuilder AppendRange(IEnumerable<byte[]> values)

Parameters

values IEnumerable<byte[]>

Values to add.

Returns

TBuilder

Returns the builder (for fluent-style composition).

AppendRange(IEnumerable<byte>)

Append an enumerable collection of single-byte values to the array.

public TBuilder AppendRange(IEnumerable<byte> values)

Parameters

values IEnumerable<byte>

Single-byte values to add.

Returns

TBuilder

Returns the builder (for fluent-style composition).

Remarks

Note that this method appends multiple values, each of which is a single byte

Build(ArrayData)

protected abstract TArray Build(ArrayData data)

Parameters

data ArrayData

Returns

TArray

Build(MemoryAllocator)

Build an Arrow array from the appended contents so far.

public TArray Build(MemoryAllocator allocator = null)

Parameters

allocator MemoryAllocator

Optional memory allocator.

Returns

TArray

Returns an array of type TArray.

Clear()

Clear all contents appended so far.

public TBuilder Clear()

Returns

TBuilder

Returns the builder (for fluent-style composition).

Reserve(int)

public TBuilder Reserve(int capacity)

Parameters

capacity int

Returns

TBuilder

Resize(int)

public TBuilder Resize(int length)

Parameters

length int

Returns

TBuilder

Set(int, byte)

public TBuilder Set(int index, byte value)

Parameters

index int

value byte

Returns

TBuilder

Swap(int, int)

public TBuilder Swap(int i, int j)

Parameters

i int

j int

Returns
