public class TemplateCall
extends Object

Runtime presentation of a template invocation or call site. Handles arguments, prepares template context for a call. Represents node<ITemplateCall>.

Constructor	Description
TemplateCall(String[] parameterNames, Object[] arguments)	Transition from TemplateDeclaration that knows its arguments at construction time to TD that evaluates argument values prior to call and therefore can cache and reuse template runtime nodes (i.e.
TemplateCall(SNode templateCall)	At the moment, we handle ITemplateCall only, the reference to TemplateDeclaration with accompanying arguments.

Constructor Detail

TemplateCall

public TemplateCall(@NotNull
                    SNode templateCall)

At the moment, we handle ITemplateCall only, the reference to TemplateDeclaration with accompanying arguments. Elements with references to TemplateDeclaration without arguments (like WeaveEach) shall not get here (although it's not a big deal to handle it here, just keep myArguments empty, and return outerContext unchanged). The reason it's not done here as this knowledge (which consequence is ITemplateCall) is static, and I don't want runtime checks for static knowledge

Parameters:

templateCall - ITemplateCall node

TemplateCall

public TemplateCall(@Nullable
                    String[] parameterNames,
                    @Nullable
                    Object[] arguments)

Transition from TemplateDeclaration that knows its arguments at construction time to TD that evaluates argument values prior to call and therefore can cache and reuse template runtime nodes (i.e. TemplateContainer)

Parameters:

parameterNames - name of template parameter, if any

arguments - values of template parameters

Method Detail

argumentsMismatch

public boolean argumentsMismatch()

Returns:

true iff there are arguments or parameters, but their count doesn't match

prepareCallContext

@NotNull
public TemplateContext prepareCallContext(@NotNull
                                          TemplateContext outerContext)
                                   throws GenerationFailureException

Throws:

GenerationFailureException
