Constructor Detail

MomentData

public MomentData()

Create a new date data object with the current date and default type.

MomentData

public MomentData(MomentData data,
                  boolean deep)

Deep or shallow copy constructor. If it is shallow, then the new object shares an underlying type with the original object. If it is deep, then the type is dupped.

Parameters:

data - source data (may be null)

deep - determine if the copying is deep or shallow

TimestampData.getType(), Type.dup()

MomentData

public MomentData(DateFormatType type)

Create a new moment data object with the current time and given type.

Parameters:

type - moment type

MomentData

public MomentData(DateFormatType type,
                  java.util.Date value)

Create a new moment data object with the given type and value.

Parameters:

type - date type

value - date value (may be null)

See Also:

MomentData(DateFormatType,long)

MomentData

public MomentData(DateFormatType type,
                  long milliseconds)

Create a new moment data object with the given type and value.

Parameters:

type - date type

milliseconds - date value

MomentData

public MomentData(DateFormatType type,
                  java.lang.String stringValue,
                  java.text.ParsePosition status)
           throws InvalidDataException

Creates a moment data value from a string value.

Parameters:

stringValue - string value to be parsed

status - parse status (may be null)

Throws:

InvalidDataException - if string value could not be parser
