Text Documents

PBTextDocument

Opaque object handle:

This object maintains an internal reference count. When the reference count reaches zero, the object will be automatically deallocated. To increment the reference count, call PBTextDocumentRetain; to decrement the reference count, call PBTextDocumentRelease. These functions are thread-safe.

PBTextDocumentBuilder

Opaque object handle:

This object maintains an internal reference count. When the reference count reaches zero, the object will be automatically deallocated. To increment the reference count, call PBTextDocumentBuilderRetain; to decrement the reference count, call PBTextDocumentBuilderRelease. These functions are thread-safe.

PBPositionedTextAttribute

Structure: A text attribute and the position from where to apply it.

Fields

start (uint32_t): A position in the text document string, in bytes. This must be at a UTF-8 codepoint boundary. The text attribute will be applied starting from this offset until either the end of the string, or the next attribute of the same type, whichever comes first.

attribute (PBTextAttribute): The text attribute itself.

PBRangedTextAttribute

Structure: A text attribute and the range in which to apply it.

Fields

start (uint32_t): A position in the text document string, in bytes. This must be at a UTF-8 codepoint boundary.

end (uint32_t): A position in the text document string, in bytes. This must be at a UTF-8 codepoint boundary.

attribute (PBTextAttribute): The text attribute itself.

PBMarkdownDocumentFlags
