## Doc {id="doc",tag="cdef class",source="spacy/tokens/doc.pxd"}
|
|
|
|
The `Doc` object holds an array of [`TokenC`](/api/cython-structs#tokenc)
|
|
structs.

|
|
[`LexemeC`](/api/cython-structs#lexemec) or
|
|
[`TokenC`](/api/cython-structs#tokenc) pointer, using Cython's
|
|
[fused types](http://cython.readthedocs.io/en/latest/src/userguide/fusedtypes.html).

|
|
>
|
|
> doc = Doc(Vocab())
