# `LeXtract.Extraction`
[🔗](https://github.com/YgorCastor/lextract.git/blob/main/lib/lextract/extraction.ex#L1)

Represents a single extracted entity with alignment information.

## Fields

* `:extraction_class` - Type/category of extraction (e.g., "person", "medication")
* `:extraction_text` - The actual extracted text
* `:char_interval` - Character position in source text
* `:alignment_status` - Quality of text alignment (see `AlignmentStatus`)
* `:extraction_index` - Position in extraction sequence (0-based)
* `:group_index` - Grouping identifier for related extractions
* `:description` - Optional description of the extraction
* `:attributes` - Additional structured attributes (e.g., dosage, frequency)
* `:token_interval` - Token position in source text

## Examples

    iex> extraction = %LeXtract.Extraction{
    ...>   extraction_class: "medication",
    ...>   extraction_text: "aspirin 81mg",
    ...>   char_interval: %LeXtract.CharInterval{start_pos: 0, end_pos: 12}
    ...> }
    iex> extraction.extraction_class
    "medication"

# `t`

```elixir
@type t() :: %LeXtract.Extraction{
  alignment_status: LeXtract.AlignmentStatus.t() | nil,
  attributes: map() | nil,
  char_interval: LeXtract.CharInterval.t() | nil,
  description: String.t() | nil,
  extraction_class: String.t(),
  extraction_index: non_neg_integer() | nil,
  extraction_text: String.t(),
  group_index: non_neg_integer() | nil,
  token_interval: LeXtract.TokenInterval.t() | nil
}
```

# `aligned?`

```elixir
@spec aligned?(t()) :: boolean()
```

Returns true if the extraction has alignment information.

## Examples

    iex> extraction = %LeXtract.Extraction{extraction_class: "person", extraction_text: "John Doe"}
    iex> LeXtract.Extraction.aligned?(extraction)
    false

# `has_attributes?`

```elixir
@spec has_attributes?(t()) :: boolean()
```

Returns true if the extraction has attributes.

## Examples

    iex> extraction = %LeXtract.Extraction{extraction_class: "person", extraction_text: "John Doe"}
    iex> LeXtract.Extraction.has_attributes?(extraction)
    false
