MFDataModelFormatter

MFDataModelFormatter(MFDataModel.Message dm,
 Locale locale,
 MFFunctionRegistry customFunctionRegistry)

Method Details

format

String format(Map<String,Object> arguments)

findBestMatchingPattern

private MFDataModel.Pattern findBestMatchingPattern(MFDataModel.SelectMessage sm,
 Map<String,Object> variables,
 Map<String,Object> arguments)

sortVariants

private static int sortVariants(MFDataModelFormatter.IntVarTuple o1,
 MFDataModelFormatter.IntVarTuple o2)

matchSelectorKeys

private List<String> matchSelectorKeys(MFDataModelFormatter.ResolvedSelector rv,
 List<String> keys)

spec: The method MatchSelectorKeys is determined by the implementation. It takes as arguments a resolved _selector_ value `rv` and a list of string keys `keys`, and returns a list of string keys in preferential order. The returned list MUST contain only unique elements of the input list `keys`. The returned list MAY be empty. The most-preferred key is first, with each successive key appearing in order by decreasing preference.

formattingError

private static void formattingError(String message)

getFormattingFunctionFactoryByName

private FormatterFactory getFormattingFunctionFactoryByName(Object toFormat,
 String functionName)

resolveLiteralOrVariable

private static Object resolveLiteralOrVariable(MFDataModel.LiteralOrVariableRef value,
 Map<String,Object> localVars,
 Map<String,Object> arguments)

convertOptions

private static Map<String,Object> convertOptions(Map<String,MFDataModel.Option> options,
 Map<String,Object> localVars,
 Map<String,Object> arguments)

formatExpression

private FormattedPlaceholder formatExpression(MFDataModel.Expression expression,
 Map<String,Object> variables,
 Map<String,Object> arguments)

Formats an expression.

Parameters:

expression - the expression to format

variables - local variables, created from declarations (`.input` and `.local`)

arguments - the arguments passed at runtime to be formatted (`mf.format(arguments)`)

resolveDeclarations

private Map<String,Object> resolveDeclarations(List<MFDataModel.Declaration> declarations,
 Map<String,Object> arguments)
