CompiledCustomFEELFunction

public CompiledCustomFEELFunction(String name,
                                  List<String> parameters,
                                  Function<EvaluationContext,Object> body)

CompiledCustomFEELFunction

public CompiledCustomFEELFunction(String name,
                                  List<String> parameters,
                                  Function<EvaluationContext,Object> body,
                                  EvaluationContext ctx)

Method Detail

getParameterNames

public List<List<String>> getParameterNames()

Description copied from interface: FEELFunction

Returns the parameter names for each supported signature.

Specified by:

getParameterNames in interface FEELFunction

Overrides:

getParameterNames in class BaseFEELFunction

Returns:

a List of Lists of Strings with the parameter names. For a function with multiple signatures, each element of the list returns the names of the parameters of one signature. E.g.: the substring function has 2 supported signatures: substring( string, start position ) substring( string, start position, length ) So this method will return: { { "string", "start position" }, { "string", "start position", "length" } }

isProperClosure

public boolean isProperClosure()

getEvaluationContext

public EvaluationContext getEvaluationContext()

invoke

public FEELFnResult<Object> invoke(EvaluationContext ctx,
                                   Object[] params)

Description copied from class: BaseFEELFunction

this method should be overriden by custom function implementations that should be invoked reflectively

Overrides:

invoke in class BaseFEELFunction

Returns:

isCustomFunction

protected boolean isCustomFunction()

Overrides:

isCustomFunction in class BaseFEELFunction

toString

public String toString()

Overrides:

toString in class Object
