Description

Raw byte array. Contains bytes. Optimized for memory usage, can’t fragment the memory.

Member Function Description

Create from a generic array.

  • void append ( int byte )

Append an element at the end of the array (alias of push_back).

Append a PoolByteArray at the end of this array.

Returns a new PoolByteArray with the data compressed. Set the compression mode using one of File‘s COMPRESS_* constants.

Returns a new PoolByteArray with the data decompressed. Set buffer_size to the size of the uncompressed data. Set the compression mode using one of File‘s COMPRESS_* constants.

  • String get_string_from_ascii ( )

Returns a copy of the array’s contents as String. Fast alternative to PoolByteArray.get_string_from_utf8 if the content is ASCII-only. Unlike the UTF-8 function this function maps every byte to a character in the array. Multibyte sequences will not be interpreted correctly. For parsing user input always use PoolByteArray.get_string_from_utf8.

  • String get_string_from_utf8 ( )

Returns a copy of the array’s contents as String. Slower than PoolByteArray.get_string_from_ascii but supports UTF-8 encoded data. Use this function if you are unsure about the source of the data. For user input this function should always be preferred.

Insert a new element at a given position in the array. The position must be valid, or at the end of the array (pos==size()).

  • void invert ( )

Reverse the order of the elements in the array (so first element will now be the last).

  • void push_back ( int byte )

Append an element at the end of the array.

  • void remove ( int idx )

Remove an element from the array by index.

  • void resize ( int idx )

Set the size of the array. If the array is grown reserve elements at the end of the array. If the array is shrunk truncate the array to the new size.

  • void set ( int idx, int byte )

Change the byte at the given index.

Return the size of the array.

Returns the slice of the PoolByteArray between indices (inclusive) as a new PoolByteArray. Any negative index is considered to be from the end of the array.
