 @Nonnull
 String inputText)

Operates with ref alias macro context.

Method Details

getValue

public String getValue()
                throws EvalException

Returns a result value when processing ends.

Throws:

EvalException

evaluateNext

public boolean evaluateNext()
                     throws EvalException

Evaluates next part of a macro, returns true if has next.

Throws:

EvalException

evaluateAll

public String evaluateAll()
                   throws EvalException

Evaluates the macro. Returns evaluated value.

Throws:

EvalException

reevaluateRootLevel

protected boolean reevaluateRootLevel(@Nonnull
 RefAliasContext root)
                               throws CtxEvalException

Description copied from class: MacroProcessorBase

Invoked on the end of root macro processing. Should drop text into tail and parse again. Returns true if text has changed after extra processing step.

Specified by:

reevaluateRootLevel in class MacroProcessorBase<RefAliasContext>

Throws:

CtxEvalException

reduce

protected void reduce(@Nonnull
 RefAliasContext parent,
 @Nonnull
 RefAliasContext child)
               throws CtxEvalException

Description copied from class: MacroProcessorBase

Child will be thrown away. Child is evaluated - content in it's text. Parent may has an arguments, which should be reevaluated too. Sample: this.tail.append(parent.args).append(child.text).append(")"); parent.args.clear();

Specified by:

reduce in class MacroProcessorBase<RefAliasContext>

Throws:

CtxEvalException

createChildContext

protected RefAliasContext createChildContext(@Nonnull
 RefAliasContext parent,
 @Nonnull
 String macro)

Specified by:

createChildContext in class MacroProcessorBase<RefAliasContext>

notifyRefsFound

protected abstract void notifyRefsFound(RefAliasContext context,
 ArgsParser.Result args)
                                 throws CtxEvalException

Throws:

CtxEvalException
