serialize

public static String serialize(TemporalAccessor value)

Serializer encapsulates the logic to serialize to string.

parse

public static void parse(SearchConstants.Prefix prefix,
                         QueryParameterValue parameterValue,
                         String v)
                  throws FHIRSearchException

parses the value into a set of bounds/value and adds to parameter value.

Parameters:

prefix -

parameterValue -

v -

Throws:

FHIRSearchException

parse

public static TemporalAccessor parse(String value)
                              throws FHIRSearchException

Parses the value into a set of bounds/value and adds to parameter value. The value will be truncated to a microsecond precision after being parsed.

Parameters:

value - The date/time value to be parsed

Returns:

A TemporalAccessor object representing the parsed and truncated date/time value

Throws:

FHIRSearchException

parseQuiet

public static TemporalAccessor parseQuiet(String value)

Parses quiet the value into a set of bounds/value and adds to parameter value. The value will be truncated to a microsecond precision after being parsed.

Parameters:

value - The date/time value to be parsed

Returns:

A TemporalAccessor object representing the parsed and truncated date/time value, or null if the value could not be parsed successfully
