Class SoFieldContainer

    • Method Detail

      • getAllFields

        public SoField[] getAllFields()
        Returns the fields contained by this container.

      • copyFieldValues

        public void copyFieldValues​(SoFieldContainer fc)
        Calls copyFieldValues(fc, false).

      • fieldsAreEqual

        public boolean fieldsAreEqual​(SoFieldContainer fc)
        Returns true if this object's fields are exactly equal to fc's fields. If fc is not exactly same type as this object, false is returned.

      • copyFieldValues

        public void copyFieldValues​(SoFieldContainer fc,
                            boolean copyConnections)
        Copies the contents of fc's fields into this object's fields. fc must be the same type as this object. If copyConnections is true, then if any of fc's fields are connected then this object's fields will also be connected to the same source.

      • set

        public boolean set​(java.lang.String fieldDataString)
        Sets one or more fields in this object to the values specified in the given string, which should be a string in the Open Inventor file format. true is returned if the string was valid Open Inventor file format.

        For example, you could set the fields of an SoCube by doing: 

         SoCube cube = new SoCube();
 cube.set( "width 1.0 height 2.0 depth 3.2" );

      • getEventIn

        public SoField getEventIn​(java.lang.String fieldName)
        Returns a the eventIn with the given name. If no such eventIn exists, NULL is returned.

      • hasDefaultValues

        public boolean hasDefaultValues()
        Returns true if all of the object's fields have their default values. This will return true even if a field's isDefault() method returns false - for example, if a field's default value is 0.0 and you setValue(0.0) that field, the default flag will be set to false (because it would be too slow to compare the field against its default value every time setValue is called). However, hasDefaultValues() would return true in this case.

      • setToDefaults

        public void setToDefaults()
        Sets all fields in this object to their default values.

      • getField

        public SoField getField​(java.lang.String fieldName)
        Returns a the field of this object whose name is fieldName. Returns NULL if there is no field with the given name.

      • enableNotify

        public boolean enableNotify​(boolean flag)
        Notification at this Field Container is enabled (if flag == true) or disabled (if flag == false). The returned Boolean value indicates whether notification was enabled immediately prior to applying this method.

      • getEventOut

        public SoField getEventOut​(java.lang.String fieldName)
        Returns the eventOut with the given name. If no such eventOut exists, NULL is returned.

      • isNotifyEnabled

        public boolean isNotifyEnabled()
        Notification is the process of telling interested objects that this object has changed. Notification is needed to make engines and sensors function, is used to keep SoPaths up to date when the scene graph's topology changes, and is also used to invalidate rendering or bounding box caches.

        Notification is normally enabled, but can be disabled on a node by node (or engine by engine) basis. If you are making extensive changes to a large part of the scene graph then disabling notification can increase performance, at the expense of increased responsibility for making sure that any interested engines, sensors or paths are kept up to date.

        For example, if you will be making a lot of changes to a small part of your scene graph and you know that there are no engines or sensors attached to nodes in that part of the scene graph, you might disable notification on the nodes you are changing, modify them, re-enable notification, and then touch() one of the nodes to cause a redraw.

        However, you should profile your application and make sure that notification is taking a significant amount of time before going to the trouble of manually controlling notification.

      • get

        public java.lang.String get()
        Returns the values of the fields of this object in the Open Inventor ASCII file format in the given string. Fields whose isDefault() bit is set will not be part of the string. You can use the SoField.get() method to get a field's value as a string even if has its default value.

      • getFieldName

        public java.lang.String getFieldName​(SoField field)
        Returns the name of the given field in the fieldName argument. Returns false if field is not a member of this object.
