type - A name for the data type. When getting custom data, use this name for verification.

obj - An object that contains the custom data. The class that defines this object must implement Serializable. If desired, you can override readObject and writeObject.

DItem.setValueCustomData(java.lang.String, java.lang.Object)

setValueCustomData

public void setValueCustomData(java.lang.Object obj)

Sets the value of an item to custom data from an object.

The new value replaces the existing value.

To keep the changes, you must call Document.save after calling setValueCustomData.

The custom data cannot exceed 64K.

If you intend to get the custom data through a language binding other than Java, use a "Bytes" method.

Specified by:

setValueCustomData in interface DItem

Parameters:

obj - An object that contains the custom data. The class that defines this object must implement Serializable. If desired, you can override readObject and writeObject.
