Examples of org.apache.derby.iapi.types.DataValueDescriptor.cloneValue()

org.apache.derby.iapi.types.DataValueDescriptor.cloneValue()

Clone this DataValueDescriptor. Results in a new object that has the same value as this but can be modified independently.

Even though the objects can be modified independently regardless of the value of {@code forceMaterialization}, both the clone and the original may be dependent on the store state if {@code forceMaterialization} is set to {@code false}. An example is if you need to access the value you just read using {@code cloneValue}after the current transaction has ended, or after the source result set has been closed. @param forceMaterialization any streams representing the data value willbe materialized if {@code true}, the data value will be kept as a stream if possible if {@code false} @return A clone of the {@code DataValueDescriptor} with the same initialvalue as this.
