Class InterpretingELExpressionParser

java.lang.Object

io.micronaut.el.interpreter.InterpretingELExpressionParser

All Implemented Interfaces:

ELExpressionParser

@Internal
public final class InterpretingELExpressionParser
extends Object
implements ELExpressionParser

Creates the expressions that were not compiled at compilation time by parsing them at runtime.

The implementation is registered as a service, so adding this module to the runtime classpath is enough to make jakarta.el.ExpressionFactory accept expression strings that are only known at runtime.

Since:

1.0
