[jboss-jira] [JBoss JIRA] (DROOLS-3112) FEEL Compiler: modularize FEELImpl compiler/interpreter vs. DMNFEELHelper

FEEL Compiler: modularize FEELImpl compiler/interpreter vs. DMNFEELHelper -------------------------------------------------------------------------- Key: DROOLS-3112 URL: https://issues.jboss.org/browse/DROOLS-3112 Project: Drools Issue Type: Enhancement Reporter: Edoardo Vacchi Assignee: Edoardo Vacchi Priority: Major Labels: drools-core Code in FEELImpl could be reused in the DMNFEELHelper, but it cannot be shared, because FEELImpl exposes an interface to evaluate expressions, while DMNFEELHelper needs access to the compiler backend. Solution: separate the compilation pipeline and the interpreter pipeline from the public FEEL interface to promote code reuse. In particular, CompilerBytecodeLoader can be probably split between some kind of CompiledUnit+CompiledUnaryTest impls that provide methods to retrieve Java source code and/or JVM bytecode.
