Method Detail

register

public void register(NamedFunction f,
                     boolean isPublic)

Specified by:

register in interface FunctionDefContextInternal

invoke

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

Specified by:

invoke in interface FunctionDefContext

invoke

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

Specified by:

invoke in interface FunctionDefContext

typesForParameters

public java.util.List<BackendType> typesForParameters(BackendTypesystem ts,
                                                      java.util.List<?> params)

is public only for testing purposes

findFunctionCandidates

public java.util.Collection<Function> findFunctionCandidates(QualifiedName functionName,
                                                             java.util.List<BackendType> paramTypes,
                                                             boolean firstParamIsThis)

is public only for testing purposes

getByFirstParameterType

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

Description copied from interface: FunctionDefContext

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

Specified by:

getByFirstParameterType in interface FunctionDefContext

getMatch

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

Description copied from interface: FunctionDefContext

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

Specified by:

getMatch in interface FunctionDefContext

hasMatch

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

Description copied from interface: FunctionDefContext

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.

Specified by:

hasMatch in interface FunctionDefContext

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

getPublicFunctions

public java.util.Collection<NamedFunction> getPublicFunctions()

Specified by:

getPublicFunctions in interface FunctionDefContext

getAllFunctions

public java.util.Collection<NamedFunction> getAllFunctions()

Specified by:

getAllFunctions in interface FunctionDefContext
