- if the formula contains syntax errors.public java.lang.Object computeValue() throws DataSourceException
The value depends (obviously) on the expression implementation.
DataSourceException
public java.lang.Object clone() throws java.lang.CloneNotSupportedException
Expression maintain no state, cloning is done at the beginning of the report processing to disconnect the used expression from any other object space.
clone

java.lang.CloneNotSupportedException
- this should never happen.
