Interface PLJavaBasedLanguage.Template

Enclosing interface:

PLJavaBasedLanguage

Functional Interface:

This is a functional interface and can therefore be used as the assignment target for a lambda expression or method reference.

@FunctionalInterface
public static interface PLJavaBasedLanguage.Template

The result of a prepare call on a PL/Java-based routine.

An instance should depend only on the static catalog information for the routine as passed to prepare, and may encapsulate any values that can be precomputed from that information alone. Its specialize method will be called, passing information specific to a call site, to obtain a PLJavaBasedLanguage.Routine.

Method Summary

Modifier and Type	Method	Description
PLJavaBasedLanguage.Routine	specialize(RegProcedure.Lookup flinfo)	Given the information present at a particular call site, specialize this template into a Routine that will handle calls through this call site.

Method Details

specialize

PLJavaBasedLanguage.Routine specialize(RegProcedure.Lookup flinfo)
                                throws SQLException

Given the information present at a particular call site, specialize this template into a Routine that will handle calls through this call site.

Typical activities for specialize would be to consult flinfo's inputsDescriptor and outputsDescriptor for the number and types of the expected input and output parameters, though it is unnecessary if the tuple descriptors obtained at prepare time included no unresolved types. The inputsAreSpread method should be consulted if the routine has a variadic parameter of the wildcard "any" type.

Throws:

SQLException
