Perhaps someday instead of having a giant "instanceof" case statement to pick an impl, we can add a "RangeFacetable" marker interface to FieldTypes and they can return instances of these directly from some method -- but until then, keep this locked down and private.

Method Summary

Modifier and Type	Method and Description
T	addGap(T value, java.lang.String gap) Adds the String gap param to a low Range endpoint value to determine the corrisponding high Range endpoint value, throwing a useful exception if not possible.
java.lang.String	formatValue(T val) Formats a Range endpoint for use as a range label name in the response.
java.lang.Object	getGap(java.lang.String gap) Parses a String param into a value that represents the gap and can be included in the response, throwing a useful exception if not possible.
T	getValue(java.lang.String rawval) Parses a String param into an Range endpoint value throwing a useful exception if not possible
protected abstract T	parseAndAddGap(T value, java.lang.String gap) Adds the String gap param to a low Range endpoint value to determine the corrisponding high Range endpoint value.
protected java.lang.Object	parseGap(java.lang.String rawval) Parses a String param into a value that represents the gap and can be included in the response.
protected abstract T	parseVal(java.lang.String rawval) Parses a String param into an Range endpoint.

RangeEndpointCalculator

public RangeEndpointCalculator(SchemaField field)

Method Detail

formatValue

public java.lang.String formatValue(T val)

Formats a Range endpoint for use as a range label name in the response. Default Impl just uses toString()

getValue

public final T getValue(java.lang.String rawval)

Parses a String param into an Range endpoint value throwing a useful exception if not possible

parseVal

protected abstract T parseVal(java.lang.String rawval)
                       throws java.text.ParseException

Parses a String param into an Range endpoint. Can throw a low level format exception as needed.

Throws:

java.text.ParseException

getGap

public final java.lang.Object getGap(java.lang.String gap)

Parses a String param into a value that represents the gap and can be included in the response, throwing a useful exception if not possible. Note: uses Object as the return type instead of T for things like Date where gap is just a DateMathParser string

parseGap

protected java.lang.Object parseGap(java.lang.String rawval)
                             throws java.text.ParseException

Parses a String param into a value that represents the gap and can be included in the response. Can throw a low level format exception as needed. Default Impl calls parseVal

Throws:

java.text.ParseException

addGap

public final T addGap(T value,
                      java.lang.String gap)

Adds the String gap param to a low Range endpoint value to determine the corrisponding high Range endpoint value, throwing a useful exception if not possible.

parseAndAddGap

protected abstract T parseAndAddGap(T value,
                                    java.lang.String gap)
                             throws java.text.ParseException

Adds the String gap param to a low Range endpoint value to determine the corrisponding high Range endpoint value. Can throw a low level format exception as needed.

Throws:

java.text.ParseException
