# GH_Chunk class

Namespace: [GH_IO.Serialization](https://developer.rhino3d.com/api/gh1/namespace/gh-io.serialization.md) · Assembly: [GH_IO](https://developer.rhino3d.com/api/gh1/assembly/gh-io.md)

```cs
public class GH_Chunk : GH_IWriter, GH_IReader
```

Full implementation of GH_IChunk, GH_IReader, GH_IWriter, GH_IBinarySupport and GH_IXmlSupport. Instances of this class are usually disguised as one of the interfaces it implements.

**Derived types:** [GH_LooseChunk](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-loosechunk.md)

## Constructors

- [GH_Chunk](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/ctor.md): (4 overloads) Blank constructor. You typically do not need to create your own Chunks. The GH_Archive class will create top-level chunks and existing chunks can create child chunks.

## Fields

- [m_archive](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-archive.md): Pointer to the archive that owns the Root of the tree this chunk belongs to.
- [m_chunks](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-chunks.md): Dictionary of sub-chunks contained within this chunk.
- [m_comments](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-comments.md): List of text comments. This list is automatically instantiated once the first comment is added.
- [m_index](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-index.md): Index of this chunk. This field is set only once, during construction. A negative index indicates no index qualifier has been set.
- [m_items](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-items.md): The list of nodes contained within this chunk.
- [m_name](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/m-name.md): Name of this chunk. This field is set only once, during construction.
- [name_comp](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/name-comp.md): (static) Comparison flag to use when comparing names.

## Properties

- [Archive](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/archive.md): Gets a pointer to the archive that owns the Root of the tree this chunk belongs to.
- [ArchiveLocation](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/archivelocation.md): Gets a string representing the URI with which the archive is associated. The location may be a null string.
- [ChunkCount](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/chunkcount.md): Gets the number of child chunks contained in this chunk. The set of all child chunks is referred to as a 'litter'.
- [Chunks](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/chunks.md): Gets a pointer to the internal list of child chunks. Do not access this list unless you know what you are doing.
- [HasComments](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/hascomments.md): Gets a value that indicates whether or not comments have been stored in this chunk.
- [HasIndex](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/hasindex.md): Gets the index existence implication. The item is considered to have an index qualifier if the index value is larger than or equal to zero.
- [HasName](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/hasname.md): Gets the name validity of this item. The item is considered to have an invalid name if string.IsNullOrEmpty(name)
- [Index](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/index.md): Gets the index of this chunk. The index is set by the owner of this chunk. Indices smaller than zero imply no index has been set. The combination of name+index is always unique among a set of chunks in the same litter.
- [ItemCount](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/itemcount.md): Gets the number of items contained in this chunk.
- [Items](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/items.md): Gets a pointer to the internal list of items. Do not access this list unless you know what you are doing.
- [Name](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/name.md): Gets the name of this chunk. The name is set by the owner of this chunk. Names must be at least 1 character long. The combination of name+index is always unique among a set of chunks in a single litter.

## Methods

- [AddComment](https://developer.rhino3d.com/api/gh1/type/gh-io.serialization.gh-chunk/addcomment.md): Adds a text comment to this chunk.
