ByteArray

class ByteArray(*args, **kwargs)
Constructors:

ByteArray()

Methods

class ByteArray
append(array: Sequence[int], data: int, len: int) → bytes

Adds the given bytes to the end of the GByteArray. The array will grow in size automatically if necessary.

Parameters:

  • array – a GByteArray

  • data – the byte data to be added

  • len – the number of bytes to add

free(array: Sequence[int], free_segment: bool) → int

Frees the memory allocated by the GByteArray. If free_segment is True it frees the actual byte data. If the reference count of array is greater than one, the GByteArray wrapper is preserved but the size of array will be set to zero.

Parameters:

  • array – a GByteArray

  • free_segment – if True the actual byte data is freed as well

free_to_bytes(array: Sequence[int]) → Bytes

Transfers the data from the GByteArray into a new immutable Bytes.

The GByteArray is freed unless the reference count of array is greater than one, the GByteArray wrapper is preserved but the size of array will be set to zero.

This is identical to using new_take() and free() together.

Added in version 2.32.

Parameters:

array – a GByteArray

new() → bytes

Creates a new GByteArray with a reference count of 1.

new_take(data: Sequence[int]) → bytes

Creates a byte array containing the data. After this call, data belongs to the GByteArray and may no longer be modified by the caller. The memory of data has to be dynamically allocated and will eventually be freed with free().

Do not use it if len is greater than %G_MAXUINT. GByteArray stores the length of its data in guint, which may be shorter than gsize.

Added in version 2.32.

Parameters:

data – byte data for the array

prepend(array: Sequence[int], data: int, len: int) → bytes

Adds the given data to the start of the GByteArray. The array will grow in size automatically if necessary.

Parameters:

  • array – a GByteArray

  • data – the byte data to be added

  • len – the number of bytes to add

remove_index(array: Sequence[int], index_: int) → bytes

Removes the byte at the given index from a GByteArray. The following bytes are moved down one place.

Parameters:

  • array – a GByteArray

  • index – the index of the byte to remove

remove_index_fast(array: Sequence[int], index_: int) → bytes

Removes the byte at the given index from a GByteArray. The last element in the array is used to fill in the space, so this function does not preserve the order of the GByteArray. But it is faster than remove_index().

Parameters:

  • array – a GByteArray

  • index – the index of the byte to remove

remove_range(array: Sequence[int], index_: int, length: int) → bytes

Removes the given number of bytes starting at the given index from a GByteArray. The following elements are moved to close the gap.

Added in version 2.4.

Parameters:

  • array – a GByteArray

  • index – the index of the first byte to remove

  • length – the number of bytes to remove

set_size(array: Sequence[int], length: int) → bytes

Sets the size of the GByteArray, expanding it if necessary.

Parameters:

  • array – a GByteArray

  • length – the new size of the GByteArray

sized_new(reserved_size: int) → bytes

Creates a new GByteArray with reserved_size bytes preallocated. This avoids frequent reallocation, if you are going to add many bytes to the array. Note however that the size of the array is still 0.

Parameters:

reserved_size – number of bytes preallocated

sort(array: Sequence[int], compare_func: Callable[[None, None], int]) → None

Sorts a byte array, using compare_func which should be a qsort()-style comparison function (returns less than zero for first arg is less than second arg, zero for equal, greater than zero if first arg is greater than second arg).

If two array elements compare equal, their order in the sorted array is undefined. If you want equal elements to keep their order (i.e. you want a stable sort) you can write a comparison function that, if two elements would otherwise compare equal, compares them by their addresses.

Parameters:

  • array – a GByteArray

  • compare_func – comparison function

sort_with_data(array: Sequence[int], compare_func: Callable[[...], int], *user_data: Any) → None

Like sort(), but the comparison function takes an extra user data argument.

Parameters:

  • array – a GByteArray

  • compare_func – comparison function

  • user_data – data to pass to compare_func

Fields

class ByteArray
data

A pointer to the element data. The data may be moved as elements are added to the GByteArray

len

The number of elements in the GByteArray
