question: @ Nullable private boolean shouldAlignFieldInColumns ( @ NotNull ASTNode child ) { if ( ! mySettings . ALIGN_GROUP_FIELD_DECLARATIONS ) { return false ; } IElementType childType = child . getElementType ( ) ; ASTNode previousNode = FormatterUtil . getPreviousNonWhitespaceSibling ( child ) ; if ( childType == JavaTokenType . IDENTIFIER && ( previousNode == null || previousNode . getElementType ( ) == JavaTokenType . COMMA ) ) { return false ; } return true ; }
target:  Encapsulates alignment retrieval logic for variable declaration use-case assuming that given node is a child node of basic variable declaration node.
