Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xd::time_span. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this conversion can cause an xtd::overflow_exception for values that are near to but still in the range of either xd::time_span::min_value or xd::time_span::max_value. For example, this causes an xtd:overflow_exception in the following attempt to instantiate a xd::time_span object.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_days(time_span::max_value.total_days());

xtd::argument_exception	value is equal to xtd::double_object::NaN.

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xtd::time_span. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the double data type, this conversion can generate an xtd::overflow_exception for values that are near to but still in the range of either xtd::time_span::min_value or xtd::time_span::max_value.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_hours(time_span::max_value::total_hours());

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xtd::time_span. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this conversion can generate an xtd::overflow_exception for values that are near to but still in the range of either xtd::time_span::min_value or xtd::time_span::max_value. For example, this causes an xtd::overflow_exception in the following attempt to instantiate a xtd::time_span object.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_minutes(time_span::max_value::total_miminutes);

from_minutes() [2/2]

static time_span xtd::time_span::from_minutes ( std::chrono::minutes  value )

static

Returns a xtd::time_span that represents a specified number of minutes.

Parameters

value

A number of minutes.

Returns

An object that represents value.

from_nanoseconds() [1/2]

static time_span xtd::time_span::from_nanoseconds ( double  value )

static

Returns a xtd::time_span that represents a specified number of nanoseconds.

Parameters

value

A number of nanoseconds.

Returns

An object that represents value.

from_nanoseconds() [2/2]

static time_span xtd::time_span::from_nanoseconds ( std::chrono::nanoseconds  value )

static

Returns a xtd::time_span that represents a specified number of nanoseconds.

Parameters

value

A number of nanoseconds.

Returns

An object that represents value.

from_seconds() [1/2]

static time_span xtd::time_span::from_seconds ( double  value )

static

Returns a xtd::time_spam that represents a specified number of seconds, where the specification is accurate to the nearest millisecond.

Parameters

value

A number of minutes, accurate to the nearest second.

Returns

An object that represents value.

Exceptions

xtd::overflow_exception	value is less than xtd::time_span::min_value or greater than xtd::time_span::max_value. -or- value is xtd::double_object::positive_infinity. -or- value is xtd::double_object::negative_infinity.
xtd::argument_exception	value is equal to xtd::double_object::NaN.

Remarks

The value parameter is converted to milliseconds, which is converted to ticks, and that number of ticks is used to initialize the new xtd::time_span. Therefore, value will only be considered accurate to the nearest millisecond. Note that, because of the loss of precision of the Double data type, this conversion can generate an xtd::overflow_exception for values that are near to but still in the range of either xtd::time_span::min_value or xtd::time_span::max_value. For example, this causes an xtd::overflow_exception in the following attempt to instantiate a xtd::time_span object.

// The following throws an overflow_exception at runtime
auto max_span = time_span::from_seconds(time_span::max_value::total_seconds);

from_seconds() [2/2]

static time_span xtd::time_span::from_seconds ( std::chrono::seconds  value )

static

Returns a xtd::time_span that represents a specified number of seconds.

Parameters

value

A number of seconds.

Returns

An object that represents value.

from_ticks() [1/2]

static time_span xtd::time_span::from_ticks ( int64  value )

static

Returns a xtd::time_spam that represents a specified time, where the specification is in units of ticks.

Parameters

value

A number of ticks that represent a time.

Returns

An object that represents value.

from_ticks() [2/2]

static time_span xtd::time_span::from_ticks ( xtd::ticks  value )

static

Returns a xtd::time_span that represents a specified number of ticks.

Parameters

value

A number of ticks.

Returns

An object that represents value.

Remarks

This is a convenience method with the same behavior as the xtd::time_spam.xtd::time_spam (int64) constructor. A single tick represents one hundred nanoseconds or one ten-millionth of a second. There are 10,000 ticks in a millisecond.

try_parse()

static bool xtd::time_span::try_parse ( const string &  value, time_span &  result  )

static

Converts the string representation of a time interval to its xtd::time_span equivalent and returns a value that indicates whether the conversion succeeded.

Parameters

value	A string that specifies the time interval to convert.
result	When this method returns, contains an object that represents the time interval specified by value, or xtd::time_span::zero if the conversion failed.

Returns

true if s was converted successfully; otherwise, false. This operation returns false if the value parameter is empty (""), has an invalid format, represents a time interval that is less than xtd::time_span::min_value or greater than xtd::time_span::max_value, or has at least one days, hours, minutes, or seconds component outside its valid range.

equals() [3/4]

virtual bool xtd::object::equals ( const object &  obj ) const

virtualnoexcept

Determines whether the specified object is equal to the current object.

Parameters

obj	The object to compare with the current object.

Returns

true if the specified object is equal to the current object. otherwise, false.

Examples

The following code example compares the current instance with another object.

#include <xtd/console>
 
using namespace xtd;
 
auto main() -> int {
  auto object1 = new_ptr<object>();
  auto object2 = new_ptr<object>();
  
  auto object3 = object2;
  console::write_line(object1->equals(*object3));
  console::write_line(*object1 == *object3);
  object3 = object1;
  console::write_line(object1->equals(*object3));
  console::write_line(*object1 == *object3);
}
 
// This code produces the following output :
//
// false
// false
// true
// true

Reimplemented from xtd::object.

equals() [4/4]

template<typename object_a_t , typename object_b_t >

static bool xtd::object::equals ( const object_a_t &  object_a, const object_b_t &  object_b  )

inlinestaticnoexcept

Determines whether the specified object instances are considered equal.

Parameters

object_a	The first object to compare.
object_b	The second object to compare.

Returns

true if object_a is the same instance as object_b or if both are null references or if object_a(object_b) returns true. otherwise, false.

Examples

The following code example compares different objects.

#include <xtd/console>
 
using namespace xtd;
 
auto main() -> int {
  string s1 = "Tom";
  string s2 = "Carol";
  console::write_line("object::equals(\"{0}\", \"{1}\") => {2}", s1, s2, object::equals(s1, s2));
  
  s1 = "Tom";
  s2 = "Tom";
  console::write_line("object::equals(\"{0}\", \"{1}\") => {2}", s1, s2, object::equals(s1, s2));
  
  s1 = "";
  s2 = "Tom";
  console::write_line("object::equals(\"{0}\", \"{1}\") => {2}", s1, s2, object::equals(s1, s2));
  
  s1 = "Carol";
  s2 = "";
  console::write_line("object::equals(\"{0}\", \"{1}\") => {2}", s1, s2, object::equals(s1, s2));
  
  s1 = "";
  s2 = "";
  console::write_line("object::equals(\"{0}\", \"{1}\") => {2}", s1, s2, object::equals(s1, s2));
}
 
// This code produces the following output :
//
// object::equals("Tom", "Carol") => false
// object::equals("Tom", "Tom") => true
// object::equals("", "Tom") => false
// object::equals("Carol", "") => false
// object::equals("", "") => true
