Interface FunctionDefContext

All Known Subinterfaces:

FunctionDefContextInternal

All Known Implementing Classes:

FunctionDefContextImpl

public interface FunctionDefContext

A FunctionDefContext is roughly the backend representation of a compilation unit - it stands for all functions that are visible from a given point in the code, and every function knows the FunctionDefContext that is valid within its body.

Method Summary

java.util.Collection<NamedFunction>	getAllFunctions()
java.util.Collection<NamedFunction>	getByFirstParameterType(BackendType firstParameterType) for reflection.
Function	getMatch(ExecutionContext ctx, QualifiedName name, java.util.List<BackendType> params) for reflection.
java.util.Collection<NamedFunction>	getPublicFunctions()
boolean	hasMatch(ExecutionContext ctx, QualifiedName functionName, java.util.List<? extends java.lang.Object> params) for dynamic matching, e.g.
java.lang.Object	invoke(ExecutionContext ctx, QualifiedName functionName, java.util.List<? extends java.lang.Object> params)
java.lang.Object	invoke(ExecutionContext ctx, QualifiedName functionName, java.util.List<? extends java.lang.Object> params, boolean firstParamIsThis)

Method Detail

invoke

java.lang.Object invoke(ExecutionContext ctx,
                        QualifiedName functionName,
                        java.util.List<? extends java.lang.Object> params)

invoke

java.lang.Object invoke(ExecutionContext ctx,
                        QualifiedName functionName,
                        java.util.List<? extends java.lang.Object> params,
                        boolean firstParamIsThis)

getByFirstParameterType

java.util.Collection<NamedFunction> getByFirstParameterType(BackendType firstParameterType)

for reflection. This method returns all functions, both those separately registered and those "built into" the type.

getMatch

Function getMatch(ExecutionContext ctx,
                  QualifiedName name,
                  java.util.List<BackendType> params)

for reflection. This method returns all functions, both those built-into the types and those registered separately.

hasMatch

boolean hasMatch(ExecutionContext ctx,
                 QualifiedName functionName,
                 java.util.List<? extends java.lang.Object> params)

for dynamic matching, e.g. to determine if a function should be called on a collection itself or on all of its members. This method matches against all functions, both those built into the types and those registered separately.

getPublicFunctions

java.util.Collection<NamedFunction> getPublicFunctions()

getAllFunctions

java.util.Collection<NamedFunction> getAllFunctions()
