public class DateData

extends TimestampData

DateData represents a date, as opposed to time values that represent the time of day and timestamps that represent them both.

Since:

JDK1.1

Constructor Summary

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

DateData(DateData data, boolean deep)
Deep or shallow copy constructor.

DateData(DateFormatType type)
Create a new date data object with the current date and given type.

DateData(DateFormatType type, java.util.Date value)
Create a new date data object with the given type and value.

DateData(DateFormatType type, long milliseconds)
Create a new date data object with the given type and value.

DateData(DateFormatType type, java.lang.String stringValue, java.text.ParsePosition status)
Creates a date data value from a string value.

Constructor Detail

DateData

public DateData()

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

DateData

public DateData(DateData 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

See Also:

TimestampData.getType(), Type.dup()

DateData

public DateData(DateFormatType type)

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

Parameters:

type - date type

DateData

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

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

Parameters:

type - date type

value - date value (may be null)

See Also:

DateData(DateFormatType,long)

DateData

public DateData(DateFormatType type,
                long milliseconds)

Create a new date data object with the given type and value. The given milliseconds value is interpreted as a calendar date, from which all the time fields are then cleared away. The resulting milliseconds value represents the moment the spesified day begins.

Parameters:

type - date type

milliseconds - date value

See Also:

DateData(DateFormatType,java.util.Date), TimestampData.initTime(com.davisor.data.DateFormatType, long)

DateData

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

Creates a date 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

See Also:

TimestampData.setValue(String,ParsePosition)

Method Detail

toStatement

public void toStatement(java.sql.PreparedStatement statement,
                        int parameter)
                 throws java.sql.SQLException

Convert data to a prepared statement input parameter.

Specified by:

toStatement in interface DataValue

Overrides:

toStatement in class TimestampData

Throws:

java.sql.SQLException - if a SQL error occurs.

setTime

public void setTime(long milliseconds)

Sets the current date value, but enforcing dates over time by stripping all the time of day information from the given timestamp value.

Parameters:

milliseconds - date time value

See Also:

TimestampData.initTime(com.davisor.data.DateFormatType, long), TimeData.setTime(long)

dup

public com.davisor.core.Dupable dup()

Makes a deep copy of this object.

Specified by:

dup in interface com.davisor.core.Dupable

Overrides:

dup in class TimestampData
