Kenneth Knowles updated BEAM-40: -------------------------------- Fix Version/s: First stable release > Replace rawtype lambda-incompatible uses of SerializableFunction with > SimpleFunction (as appropriate) > ----------------------------------------------------------------------------------------------------- > > Key: BEAM-40 > URL: https://issues.apache.org/jira/browse/BEAM-40 > Project: Beam > Issue Type: Task > Components: sdk-java-core > Reporter: Kenneth Knowles > Priority: Minor > Labels: Java8, backward-incompatible > Fix For: First stable release > > > When a lambda or method reference is used in Java 8 to provide a > SerializableFunction<InputT, OutputT>, it is instantiated at the raw type > SerializableFunction. We occasionally require reflective access to the actual > parameter for OutputT, but it will be unavailable. > MapElements and FlatMapElements thus use the analogous abstract class > SimpleFunction in such situations to prevent use of a lambda or method > reference. They then support lambda via separate constructors that require > user help to determine the concrete output type. > This ticket calls for an audit of such situations. -- This message was sent by Atlassian JIRA (v6.3.15#6346)
