使用Java的Enterprise Architect脚本-添加CustomProperty

我想在活动图中添加一个图例，该图例将由java和ea-api以编程方式生成。我已经知道如何创建图例元素并将其显示在图中（类型：“文本”和子类型：76）：

Element legend = elements.AddNew("Color Legend", "Text");
elements.Refresh();

legend.SetSubtype(76);
legend.Update();

//Show in diagram
DiagramObject diagramObject = diagramObjects.AddNew("l=0; r=100; t=0; b=-100;", "");
diagramObjects.Refresh();
// reference the DiagramObject to the before created element
diagramObject.SetElementID(legend.GetElementID());

但这只是一个空洞的传说。所以我的问题是，如何向CustomProperties中添加一个CustomProperty。我的第一种方法是以下代码：

Collection<CustomProperty> customProperties = legend.GetCustomProperties();
CustomProperty cp = customProperties.AddNew("LegendEntryTest", "Back_Ground_Color=2124031;");
customProperties.Refresh();
legend.Update();

但这不起作用，图例仍然是空的:(

这是一个示例示例：

问候，菲尔

编辑在吉尔特·贝莱肯斯的帮助下，我解决了我的问题。现在，我使用repository.Execute（String sqlStmt）方法将自定义属性插入t_xref。以下代码是一个如何工作的小示例：

//get elementGUID of legend
String legendGUID = legend.GetElementGUID();

//create the description value for one custom_property
String name="TestColor1";
String color="3381504";
int customPropertyIndex = 0;

String description = "@PROP=@NAME="+name+"@ENDNAME;@TYPE=LEGEND_OBJECTSTYLE@ENDTYPE;@VALU=#Back_Ground_Color#="+color+";#Pen_Color#=16777215;#Pen_Size#=1;#Legend_Type#=LEGEND_OBJECTSTYLE;@ENDVALU;@PRMT="+customPropertyIndex +"@ENDPRMT;@ENDPROP;"

//add description part for the legend
description += "@PROP=@NAME=Legend@ENDNAME;@TYPE=LEGEND_STYLE_SETTINGS@ENDTYPE;@VALU=@ENDVALU;@PRMT=@ENDPRMT;@ENDPROP;"

String sqlInsertStmt="INSERT INTO t_xref "
            + "(" 
                + "Client,"
                + "XrefID,"
                + "Type,"
                + "Name,"
                + "Visibility,"
                + "Partition,"
                + "Supplier,"
                + "Description"
            + ") "
            + " VALUES ("
                +"'"+legendGUID+ "',"
                + "'{"+UUID.randomUUID().toString()+"}',"
                + "'element property',"
                + "'CustomProperties',"
                + "'Public',"
                + "'0',"
                + "'<none>',"
                + "'"+description+"'"
            + ");"
                ;

repository.Execute(sqlInsertStmt);

随着java.util.UUID我生成该领域的新GUID XrefID。

顺便说一句：要将RGB颜色转换为Enterprise Architect可以接受的颜色，可以使用以下公式：

 int colorValue = color.getRed() + (color.getGreen() * 256)
            + (color.getBlue() * 256 * 256);
