Package | Description |
---|---|
com.speedment.runtime.compute |
The Runtime Compute module adds a large number of functional interfaces to
the Speedment system that allows computations to be performed on entities in
a Stream without loosing metadata required by Speedment to optimize the
stream.
|
com.speedment.runtime.compute.expression |
Expression builders that can produce efficient and type-safe implementations
of the interfaces in the
com.speedment.enterprise.aggregator.function
package. |
com.speedment.runtime.field |
Fields expose handlers for accessing columns in generated classes and are
located in this package.
