Class EnterpriseGate

java.lang.Object

water.EnterpriseGate

public class EnterpriseGate
extends java.lang.Object

Server-side H2O-3 Secure gate for production-only capabilities. The OSS build enforces the paywall where the artifacts are actually produced, so it holds regardless of how the caller got there - REST, Flow, a patched client, an embedded H2O node, or a client-mode node that joined the cluster and pulled the model out of the DKV:

• Model MOJO: ModelMojoWriter.writeTo(OutputStream, StreamWriteOption...), the single funnel every model MOJO byte passes through, including the nested writers used for Stacked Ensembles.
• Model POJO: Model.toJava(OutputStream, boolean, boolean), which both public POJO generators route through.
• Assembly MOJO 2 pipeline: ProtobufPipelineWriter.writeTo(...). An water.rapids.Assembly carries only munging steps, never a model, but the artifact is still a .mojo zip handed to the caller.

The REST endpoints additionally call block(String) directly - ModelsHandler (fetchJavaCode, fetchMojo, exportMojo), AssemblyToMojoPipelineExportHandler.fetchMojoPipeline and AssemblyHandler.toJava. That is not the enforcement - the writers above are - but it fails the request at the API boundary with a message naming the operation the caller asked for. AssemblyHandler.toJava is the one case where the handler is the only enforcement point, because the Java text is generated afterwards by RequestServer rather than by a StreamWriter. The client-side notices in the Python/R packages are only the friendly message. Binary model export stays open by design: a model can still be moved to an H2O-3 Secure cluster, which is the intended upgrade path. What OSS will not do is convert one into a deployable scoring artifact.

Method Detail

logStartupBanner

public static void logStartupBanner()

Log the OSS-vs-Secure notice at cluster startup. Emitted via Log.info(java.lang.Object...) (not System.out) so it flows through the standard logging pipeline.

blockUnlessTestHarness

public static void blockUnlessTestHarness(java.lang.String operation)

Enforcement point for the hex.Model artifact-producing methods, which the test harness itself relies on. Identical to block(String) for every shipped cluster; a no-op under the JUnit suites. The REST layer deliberately does not use this variant - every request from a client is blocked unconditionally.

block

public static void block(java.lang.String operation)

Block a MOJO-related capability. operation is the user-facing action (e.g. "MOJO export", "MOJO import"). Always throws.
