Method Detail

textLayoutManagerRenderingAttributesForLinkAtLocationDefaultAttributes

default NSDictionary<java.lang.String,?> textLayoutManagerRenderingAttributesForLinkAtLocationDefaultAttributes(NSTextLayoutManager textLayoutManager,
                                                                                                                java.lang.Object link,
                                                                                                                NSTextLocation location,
                                                                                                                NSDictionary<java.lang.String,?> renderingAttributes)

Rendering attributes Returns a dictionary of rendering attributes for rendering NSLinkAttributeName. Just as other rendering attributes, specifying NSNull removes the attribute from the final attributes used for rendering. It has priority over the general rendering attributes.

textLayoutManagerShouldBreakLineBeforeLocationHyphenating

default boolean textLayoutManagerShouldBreakLineBeforeLocationHyphenating(NSTextLayoutManager textLayoutManager,
                                                                          NSTextLocation location,
                                                                          boolean hyphenating)

Layout behavior Invoked while determining the soft line break point. When hyphenating=NO, NSTextLayoutManager tries to find the next line break opportunity before location. When hyphenating=YES, it is an auto-hyphenation point.

textLayoutManagerTextLayoutFragmentForLocationInTextElement

default NSTextLayoutFragment textLayoutManagerTextLayoutFragmentForLocationInTextElement(NSTextLayoutManager textLayoutManager,
                                                                                         NSTextLocation location,
                                                                                         NSTextElement textElement)

NSTextLayoutFragment management Returns NSTextLayoutFragment for location in textElement. NSTextLayoutManagerDelegate could provide an NSTextLayoutFragment specialized for an NSTextElement subclass targeted for the rendering surface.
