Constructor Detail

TimeRange

public TimeRange()

Sets a default time range of the whole of today

TimeRange

public TimeRange(java.util.Calendar from,
                 java.util.Calendar to)

TimeRange

public TimeRange(java.util.Date from,
                 java.util.Date to)

TimeRange

public TimeRange(long from,
                 long to)

TimeRange

public TimeRange(TimeRange timeRange)

Constructs a copy of the supplied time range

Parameters:

timeRange - the timeRange to copy

Method Detail

copy

public Range<java.util.Date> copy()

Overrides:

copy in class AbstractRange<java.util.Date>

setMin

public void setMin(java.util.Date from)

setMin

public void setMin(long from)

adjust

public void adjust(java.util.Date lower,
                   java.util.Date upper)

Description copied from interface: Range

Adjusts the range.

Parameters:

lower - the new smallest value of the range

upper - the new largest value of the range

setMax

public void setMax(java.util.Date to)

setMax

public void setMax(long to)

minimum

public double minimum()

Description copied from interface: Range

This may be the numeric representation of lower() or it may be rounded down.

Returns:

the numeric value of the smallest value to include in the range.

maximum

public double maximum()

Description copied from interface: Range

This may be the numeric representation of upper() or it may be rounded up.

Returns:

The numeric value of the largest value to include in the range.

size

public double size()

Description copied from interface: Range

Compute the size of the range

lower

public java.util.Date lower()

Returns:

the smallest value of the range

upper

public java.util.Date upper()

Returns:

the largest value of the range

contains

public boolean contains(java.util.Date x)

Description copied from interface: Range

Determines whether the supplied point lies within this range. For continuous ranges this is interpreted as a pair of inequalities on the supplied value (i.e., min <= x <= max), but for discrete ranges the contains() method is more like a set membership test.

Returns:

a boolean to indicate whether the supplied point lies within the range

getTimeZone

public java.util.TimeZone getTimeZone()

setTimeZone

public void setTimeZone(java.util.TimeZone timeZone)

createIntermediate

public Range<java.util.Date> createIntermediate(Range<java.util.Date> target,
                                                double position)

Specified by:

createIntermediate in class AbstractRange<java.util.Date>

union

public static TimeRange union(TimeRange r1,
                              TimeRange r2)

Creates a new TimeRange as the union of two existing TimeRanges. The date format of the first time range is retained in the returned result.

Parameters:

r1 - the first TimeRange

r2 - the second TimeRange

Returns:

the union of the supplied TimeRanges

equals

public boolean equals(java.lang.Object other)

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
