protected fun layoutGraphicModifiers( dc: DrawContext?, modifiers: AVList?, osym: OrderedSymbol? ) { }
Layout static graphic modifiers around the symbol . Static modifiers are not expected to change due to changes in view . The static layout is computed when a modifier is changed , but may not be computed each frame . For example , a text modifier indicating a symbol identifier would only need to be laid out when the text is changed , so this is best treated as a static modifier . However a direction of movement line that needs to be computed based on the current eye position should be treated as a dynamic modifier .
