Runtime Code Generation

Kind: mechanism

Layer: Declarative Core

Record: architecture:runtime-code-generation

Severity: discouraged

Scope: runtime, framework

Canonical: Ontology

A mechanism that builds executable code while the program runs, from a specification such as a field mapping.

Listed in Architecture principles, after Compile-Time Evaluation and before Domain-Specific Language (DSL).
