Description

GArrowListArray is a class for list array. It can store zero or more list data. If you don't have Arrow format data, you need to use GArrowListArrayBuilder to create a new array.

GArrowLargeListArray is a class for 64-bit offsets list array. It can store zero or more list data. If you don't have Arrow format data, you need to use GArrowLargeListArrayBuilder to create a new array.

GArrowStructArray is a class for struct array. It can store zero or more structs. One struct has one or more fields. If you don't have Arrow format data, you need to use GArrowStructArrayBuilder to create a new array.

GArrowMapArray is a class for map array. It can store data with keys and items.

GArrowUnionArray is a base class for union array. It can store zero or more unions. One union has one or more fields but one union can store only one field value.

GArrowDenseUnionArray is a class for dense union array.

GArrowSparseUnionArray is a class for sparse union array.

GArrowDictionaryArray is a class for dictionary array. It can store data with dictionary and indices. It's more space effective than normal array when the array has many same values. You can convert a normal array to a dictionary array by garrow_array_dictionary_encode().

GArrowRunEndEncodedArray is a class for run-end encoded array. It can store data with run-ends and values. It's more space effective than normal array when the array has many continuous same values. You can convert a normal array to a run-end encoded array by garrow_array_run_end_encode(). You can convert a run-end encoded array to a normal array by garrow_run_end_encoded_array_decode().

garrow_run_end_encoded_array_get_values ()

GArrowArray *
garrow_run_end_encoded_array_get_values
                               (GArrowRunEndEncodedArray *array);

Parameters

Returns

The values of each run.

The physical offset to the array is applied.

garrow_run_end_encoded_array_get_logical_run_ends ()

GArrowArray *
garrow_run_end_encoded_array_get_logical_run_ends
                               (GArrowRunEndEncodedArray *array,
                                GError **error);

Parameters

array

A GArrowRunEndEncodedArray.

 

error

Return location for a GError or NULL.

[nullable]

Returns

The logical indexes of each run-end or NULL on error.

If a non-zero logical offset is set, this function allocates a new array and rewrites all the run end values to be relative to the logical offset and cuts the end of the array to the logical length.

garrow_run_end_encoded_array_get_logical_values ()

GArrowArray *
garrow_run_end_encoded_array_get_logical_values
                               (GArrowRunEndEncodedArray *array);

Parameters

Returns

The logical values of each run.

If a non-zero logical offset is set, this function allocates a new array containing only the values within the logical range.

garrow_run_end_encoded_array_find_physical_offset ()

gint64
garrow_run_end_encoded_array_find_physical_offset
                               (GArrowRunEndEncodedArray *array);

Parameters

Returns

Find the physical offset of this array.

This function uses binary-search, so it has a O(log N) cost.

Since: 13.0.0


garrow_run_end_encoded_array_find_physical_length ()

gint64
garrow_run_end_encoded_array_find_physical_length
                               (GArrowRunEndEncodedArray *array);

Parameters

Returns

Find the physical length of this array.

The physical length of an run-end encoded array is the number of physical values (and run-ends) necessary to represent the logical range of values from offset to length.

Avoid calling this function if the physical length can be estabilished in some other way (e.g. when iterating over the runs sequentially until the end). This function uses binary-search, so it has a O(log N) cost.
