com.speedment.runtime.compute.expression.Expression

Packages that use Expression

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.compute.expression.orelse
com.speedment.runtime.compute.trait	Traits used in the base package for functional interfaces.
