Method Detail

generateTimestamp

public static Timestamp generateTimestamp(Instant inst)

generateLowerBoundApproximation

public static Instant generateLowerBoundApproximation(Instant now,
                                                      Instant cur)

Calculates a lower bound absolutely. No matter if the time is AFTER the current time.

Parameters:

now - the instant representing "now"...the now to compare against for computing the "approximation" range

cur - the search parameter value instant

Returns:

generateLowerBound

public static Instant generateLowerBound(SearchConstants.Prefix prefix,
                                         TemporalAccessor value,
                                         String originalString)

generate lower bounds

Parameters:

prefix -

value -

originalString -

Returns:

generateValue

public static Instant generateValue(TemporalAccessor value,
                                    String originalString)

generateValue

public static Instant generateValue(TemporalAccessor value)

Common code to generate an instant value. If needed, this method will pad the TemporalAccessor and then interpret this value according to the default timezone of the system.

Parameters:

value -

Returns:

generateUpperBound

public static Instant generateUpperBound(DateTime value)

convenience method to generate upper bound for a DateTime value.

Parameters:

value -

Returns:

generateUpperBound

public static Instant generateUpperBound(Date value)

convenience method to generate upper bound for a Date value.

Parameters:

value -

Returns:

generateUpperBound

public static Instant generateUpperBound(SearchConstants.Prefix prefix,
                                         TemporalAccessor value,
                                         String originalString)

generate upper bounds

Parameters:

prefix -

value -

originalString -

Returns:

generateUpperBoundApproximation

public static Instant generateUpperBoundApproximation(Instant now,
                                                      Instant cur)

Calculates a lower bound absolutely. No matter if the time is AFTER the current time.

Parameters:

now -

cur -

Returns:

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
