- Converter
public abstract class AbstractConverter
extends java.lang.Object
AbstractConverter simplifies the process of implementing a converter.
AbstractConverter
protected AbstractConverter()
Restricted constructor.
getChronology
public Chronology getChronology(Object object,
Chronology chrono)
Extracts the chronology from an object of this convertor's type
where the chronology is specified.
This implementation returns the chronology specified, or the
ISO chronology in the default zone if null passed in.
object
- the object to convertchrono
- the chronology to use, null means ISO default
- the chronology, never null
getChronology
public Chronology getChronology(Object object,
DateTimeZone zone)
Extracts the chronology from an object of this convertor's type
where the time zone is specified.
This implementation returns the ISO chronology.
object
- the object to convertzone
- the specified zone to use, null means default zone
- the chronology, never null
getInstantMillis
public long getInstantMillis(Object object,
Chronology chrono)
Extracts the millis from an object of this convertor's type.
This implementation returns the current time.
object
- the object to convertchrono
- the chronology to use, which is always non-null
getPartialValues
public int[] getPartialValues(ReadablePartial fieldSource,
Object object,
Chronology chrono)
Extracts the values of the partial from an object of this converter's type.
The chrono parameter is a hint to the converter, should it require a
chronology to aid in conversion.
This implementation calls
getInstantMillis(Object,Chronology)
.
fieldSource
- a partial that provides access to the fields.
This partial may be incomplete and only getFieldType(int) should be usedobject
- the object to convertchrono
- the chronology to use, which is the non-null result of getChronology()
- the array of field values that match the fieldSource, must be non-null valid
getPartialValues
public int[] getPartialValues(ReadablePartial fieldSource,
Object object,
Chronology chrono,
DateTimeFormatter parser)
Extracts the values of the partial from an object of this converter's type.
The chrono parameter is a hint to the converter, should it require a
chronology to aid in conversion.
This implementation calls
getPartialValues(ReadablePartial,Object,Chronology)
.
fieldSource
- a partial that provides access to the fields.
This partial may be incomplete and only getFieldType(int) should be usedobject
- the object to convertchrono
- the chronology to use, which is the non-null result of getChronology()parser
- if converting from a String, the given parser is preferred
- the array of field values that match the fieldSource, must be non-null valid
getPeriodType
public PeriodType getPeriodType(Object object)
Selects a suitable period type for the given object.
object
- the object to examine
- the period type, never null
isReadableInterval
public boolean isReadableInterval(Object object,
Chronology chrono)
Checks if the input is a ReadableInterval.
If it is, then the calling code should cast and copy the fields directly.
object
- the object to convertchrono
- the chronology to use, may be null
- true if the input is a ReadableInterval
toString
public String toString()
Gets a debugging string version of this converter.
