Constructors

SliceDecoder(ReadOnlySequence<byte>, SliceEncoding, object?, int, IActivator?, int)

Constructs a new Slice decoder over a byte buffer.

public SliceDecoder(ReadOnlySequence<byte> buffer, SliceEncoding encoding, object? proxyDecodingContext = null, int maxCollectionAllocation = -1, IActivator? activator = null, int maxDepth = 3)

Parameters

buffer ReadOnlySequence<byte>

The byte buffer.

encoding SliceEncoding

The Slice encoding version.

proxyDecodingContext object

The proxy decoding context.

maxCollectionAllocation int

The maximum cumulative allocation in bytes when decoding strings, sequences, and dictionaries from this buffer.-1 (the default) is equivalent to 8 times the buffer length.

activator IActivator

The activator for decoding Slice1-encoded classes and exceptions.

maxDepth int

The maximum depth when decoding a class recursively. The default is 3.

SliceDecoder(ReadOnlyMemory<byte>, SliceEncoding, object?, int, IActivator?, int)

Constructs a new Slice decoder over a byte buffer.

public SliceDecoder(ReadOnlyMemory<byte> buffer, SliceEncoding encoding, object? proxyDecodingContext = null, int maxCollectionAllocation = -1, IActivator? activator = null, int maxDepth = 3)

Parameters

buffer ReadOnlyMemory<byte>

The byte buffer.

encoding SliceEncoding

The Slice encoding version.

proxyDecodingContext object

The proxy decoding context.

maxCollectionAllocation int

The maximum cumulative allocation in bytes when decoding strings, sequences, and dictionaries from this buffer.-1 (the default) is equivalent to 8 times the buffer length.

activator IActivator

The activator for decoding Slice1-encoded classes and exceptions.

maxDepth int

The maximum depth when decoding a class recursively. The default is 3.

Properties

Consumed

Gets the number of bytes decoded in the underlying buffer.

public readonly long Consumed { get; }

Property Value

long

Encoding

Gets the Slice encoding decoded by this decoder.

public readonly SliceEncoding Encoding { get; }

Property Value

SliceEncoding

End

Gets a value indicating whether this decoder has reached the end of its underlying buffer.

public readonly bool End { get; }

Property Value

bool

true when this decoder has reached the end of its underlying buffer; otherwise false.

ProxyDecodingContext

Gets the proxy decoding context.

public readonly object? ProxyDecodingContext { get; }

Property Value

object

Remarks

The proxy decoding context is a kind of cookie: the code that creates the decoder can store this context in the decoder for later retrieval.

public readonly long Remaining { get; }

Property Value

long

The number of bytes remaining in the underlying buffer.

Methods

CopyTo(IBufferWriter<byte>)

Copy all bytes from the underlying reader into the destination buffer writer.

public void CopyTo(IBufferWriter<byte> destination)

Parameters

Remarks

This method also moves the reader's Consumed property.

CopyTo(Span<byte>)

Copy bytes from the underlying reader into the destination to fill completely destination.

public void CopyTo(Span<byte> destination)

Parameters

destination Span<byte>

The span to which bytes of this decoder will be copied.

Remarks

This method also moves the reader's Consumed property.
