# Chilkat BinData — Ruby — v11.7.0

> Chilkat 11.7.0 · language=ckruby · class=BinData (CkBinData)
> Other versions: replace `11.7.0` in this URL. Other languages: `https://www.chilkatsoft.com/ai-docs/v/11.7.0/<lang>/classes/BinData.md`.
> Language-wide rules (install, unlock, error model, strings/bytes): `https://www.chilkatsoft.com/ai-docs/v/11.7.0/ckruby/guide.md`.

## Purpose

**Build, transform, encode, decode, inspect, and save binary data.**

`Chilkat.BinData` is a general-purpose mutable byte container used throughout Chilkat for working with binary content in memory. It can load bytes from files, byte arrays, strings, and encoded text; append additional data in many forms; retrieve content as raw bytes, chunks, text, or encoded strings; compute hashes; convert character encodings; validate UTF-8; remove byte ranges; and write the final result to files.

**Load binary content**

Load data from files, byte arrays, strings, encoded strings, or other Chilkat objects that produce binary output.

**Append and build data**

Append bytes, strings, integers, BOMs, counted strings, padded fields, encoded data, and other `BinData` objects.

**Encode and decode**

Convert binary data to and from text encodings such as Base64, hex, URL encoding, and other supported binary encodings.

**Text and charset handling**

Interpret bytes as text, append strings using a specified charset, convert character encodings, and validate UTF-8 content.

**Inspect and modify bytes**

Get byte counts, extract chunks, remove ranges, compare data, and work with specific portions of a binary buffer.

**Hash and save output**

Compute hashes for the contained data and write the resulting bytes to files or pass them to other Chilkat classes.

**Common pattern:** Load or append binary data, perform any needed encoding, decoding, hashing, charset conversion, or byte-level edits, then retrieve the result as bytes, text, an encoded string, or a file. Use `BinData` whenever a Chilkat method needs a mutable in-memory binary buffer.

For an extended overview, see [BinData Class Overview](https://www.chilkatsoft.com/bindata_class_overview.asp).

## Object creation, unlocking and error handling

**Object Creation**

```ruby
obj = Chilkat::CkBinData.new()
```

Call `Global.UnlockBundle` once at the start of the program, before using this or any other Chilkat class. Any string unlocks a fully functional 30-day trial; a purchased unlock code is used in production. See `guide.md` for the exact code in Ruby.

How failure is reported depends on the method's return type and is stated in the note under each method below. In every case the diagnostic text is in the `LastErrorText` property of the object whose method was called.

`Chilkat 11.7.0 · ckruby · BinData · AppendBom · method · since 9.5.0.62`

```ruby
# charset is a string

status = binData.AppendBom(charset);
```

Appends the appropriate BOM (byte order mark), also known as a `preamble`, for the given charset. If the `charset` has no defined BOM, then nothing is appended. An application would typically call this to append the utf-8, utf-16, or utf-32 BOM.

Returns true for success, false for failure.

### BinData.AppendByte

`Chilkat 11.7.0 · ckruby · BinData · AppendByte · method · since 9.5.0.77`

```ruby
# byteValue is an integer

status = binData.AppendByte(byteValue);
```

Appends a single byte. The `byteValue` should be a value from 0 to 255.

# str is a string

# charset is a string

status = binData.AppendCountedString(numCountBytes, bigEndian, str, charset);
```

Appends a byte count followed by the string in the desired character encoding, such as `utf-8`. The `numCountBytes` is the size in bytes of the integer to represent the byte count. If 0, then a minimal number of bytes is used. If `bigEndian` is `true`, the byte count is appended in big endian byte ordering, otherwise little-ending byte ordering. The `str` is the string to be appended. The `charset` is the character encoding, such as `utf-8`, `utf-16`, `windows-1252`, etc.

Returns true for success, false for failure.

### BinData.AppendData

`Chilkat 11.7.0 · ckruby · BinData · AppendData · method · since 11.0.0`

```ruby
# encData is a string

# encoding is a string

status = binData.AppendEncoded(encData, encoding);
```

Appends encoded binary data to the current data. The `encoding` may be `Base64`, `modBase64`, `base64Url`, `Base32`, `Base58`, `QP` (for quoted-printable), `URL` (for url-encoding), `Hex`, or any of the encodings found at [Chilkat Binary Encodings List](https://www.chilkatsoft.com/binary_encodings.asp).

# sb is a CkStringBuilder

# encoding is a string

status = binData.AppendEncodedSb(sb, encoding);

The `encoding` may be `Base64`, `modBase64`, `base64Url`, `Base32`, `Base58`, `QP` (for quoted-printable), `URL` (for url-encoding), `Hex`, or any of the encodings found at [Chilkat Binary Encodings List](https://www.chilkatsoft.com/binary_encodings.asp).

Returns true for success, false for failure.

### BinData.AppendInt2

`Chilkat 11.7.0 · ckruby · BinData · AppendInt2 · method · since 9.5.0.77`

```ruby
# value is an integer

# littleEndian is a boolean

status = binData.AppendInt2(value, littleEndian);
```

Appends a 16-bit integer (2 bytes). If `littleEndian` is `true`, then the integer bytes are appended in little-endian byte order, otherwise big-endian byte order is used.

Returns true for success, false for failure.

### BinData.AppendInt4

`Chilkat 11.7.0 · ckruby · BinData · AppendInt4 · method · since 9.5.0.77`

```ruby
# value is an integer

# littleEndian is a boolean

status = binData.AppendInt4(value, littleEndian);
```

Appends a 32-bit integer (4 bytes). If `littleEndian` is `true`, then the integer bytes are appended in little-endian byte order, otherwise big-endian byte order is used.

Returns true for success, false for failure.

### BinData.AppendPadded

`Chilkat 11.7.0 · ckruby · BinData · AppendPadded · method · since 9.5.0.80`

```ruby
# str is a string

# charset is a string

# padWithSpace is a boolean

# fieldLen is an integer

status = binData.AppendPadded(str, charset, padWithSpace, fieldLen);
```

Appends a string to this object, padded to the `fieldLen` with NULL or SPACE chars. If `padWithSpace` is `true`, then SPACE chars are used and the string is not null-terminated. If `fieldLen` is `false`, then null bytes are used. The `charset` controls the byte representation to use, such as `utf-8`.

Note: This call will always append a total number of bytes equal to `fieldLen`. If the `str` is longer than `fieldLen`, the method returns `false` to indicate failure and nothing is appended.

Returns true for success, false for failure.

### BinData.AppendSb

`Chilkat 11.7.0 · ckruby · BinData · AppendSb · method · since 9.5.0.62`

```ruby
# sb is a CkStringBuilder

Returns true for success, false for failure.

### BinData.AppendString

`Chilkat 11.7.0 · ckruby · BinData · AppendString · method · since 9.5.0.62`

```ruby
# str is a string

# charset is a string

status = binData.AppendString(str, charset);
```

Appends a string to this object. (This does not append the BOM. If a BOM is required, the AppendBom method can be called to append the appropriate BOM.)

Returns true for success, false for failure.

### BinData.ByteSwap

`Chilkat 11.7.0 · ckruby · BinData · ByteSwap · method · since 11.0.0`

```ruby
# size is an integer

status = binData.ByteSwap(size);
```

Does either 16-bit or 32-bit byte swapping of the entire contents. If `size` equals 16, then swaps in 2 bytes (e.g., 0x1234 → 0x3412). If `size` equals 32, then swaps 4 bytes (e.g., 0x12345678 → 0x78563412)

### BinData.CharsetConvert

`Chilkat 11.7.0 · ckruby · BinData · CharsetConvert · method · since 11.0.0`

```ruby
# fromCharset is a string

# toCharset is a string

# allOrNone is a boolean

status = binData.CharsetConvert(fromCharset, toCharset, allOrNone);
```

This method converts the character encoding of an object's contents from one format to another, such as from Windows-1252 to UTF-8. The `allOrNone` parameter determines error handling for unrepresentable bytes. If `allOrNone` is `true`, the object's contents remain unchanged when errors occur. If `false`, error bytes are discarded. The method returns `true` if successful and `false` if errors occur.

Returns true for success, false for failure.

### BinData.Clear

```

Return the index where the first occurrence of `str` is found. Return -1 if not found. The `startIdx` indicates the byte index where the search begins. The `charset` specifies the byte representation of `str` that is to be searched. For example, it can be `utf-8`, `windows-1252`, `ansi`, `utf-16`, etc.
