SimpleDateFormat.Format(Date, StringBuffer, FieldPosition) Method

Definition

Formats the given Date into a date/time string and appends the result to the given StringBuffer.

[Android.Runtime.Register("format", "(Ljava/util/Date;Ljava/lang/StringBuffer;Ljava/text/FieldPosition;)Ljava/lang/StringBuffer;", "GetFormat_Ljava_util_Date_Ljava_lang_StringBuffer_Ljava_text_FieldPosition_Handler")]
public override Java.Lang.StringBuffer? Format (Java.Util.Date? date, Java.Lang.StringBuffer? toAppendTo, Java.Text.FieldPosition? pos);
[<Android.Runtime.Register("format", "(Ljava/util/Date;Ljava/lang/StringBuffer;Ljava/text/FieldPosition;)Ljava/lang/StringBuffer;", "GetFormat_Ljava_util_Date_Ljava_lang_StringBuffer_Ljava_text_FieldPosition_Handler")>]
override this.Format : Java.Util.Date * Java.Lang.StringBuffer * Java.Text.FieldPosition -> Java.Lang.StringBuffer

Parameters

date
Date

the date-time value to be formatted into a date-time string.

toAppendTo
StringBuffer

where the new date-time text is to be appended.

pos
FieldPosition

keeps track on the position of the field within the returned string. For example, given a date-time text "1996.07.10 AD at 15:08:56 PDT", if the given fieldPosition is DateFormat#YEAR_FIELD, the begin index and end index of fieldPosition will be set to 0 and 4, respectively. Notice that if the same date-time field appears more than once in a pattern, the fieldPosition will be set for the first occurrence of that date-time field. For instance, formatting a Date to the date-time string "1 PM PDT (Pacific Daylight Time)" using the pattern "h a z (zzzz)" and the alignment field DateFormat#TIMEZONE_FIELD, the begin index and end index of fieldPosition will be set to 5 and 8, respectively, for the first occurrence of the timezone pattern character 'z'.

Returns

the formatted date-time string.

Attributes

Exceptions

if there are invalid characters in the pattern.

Remarks
