Duration¶

class aws_cdk.core.Duration(*args: Any, **kwargs)¶

Bases: object

Represents a length of time.

The amount can be specified either as a literal value (e.g: 10) which cannot be negative, or as an unresolved number token.

When the amount is passed as a token, unit conversion is not possible.

Methods

format_token_to_number()¶

Returns stringified number of duration.

Return type: str

is_unresolved()¶

Checks if duration is a token or a resolvable object.

Return type: bool

plus(rhs)¶

Add two Durations together.

Parameters

rhs (Duration) –

Return type

Duration

to_days(*, integral=None)¶

Return the total number of days in this Duration.

Parameters: integral (Optional[bool]) – If true, conversions into a larger time unit (e.g. Seconds to Minutes) will fail if the result is not an integer. Default: true
Return type: Union[int, float]
Returns: the value of this Duration expressed in Days.

to_hours(*, integral=None)¶

Return the total number of hours in this Duration.

Parameters: integral (Optional[bool]) – If true, conversions into a larger time unit (e.g. Seconds to Minutes) will fail if the result is not an integer. Default: true
Return type: Union[int, float]
Returns: the value of this Duration expressed in Hours.

to_human_string()¶

Turn this duration into a human-readable string.

Return type: str

to_iso_string()¶

Return an ISO 8601 representation of this period.

Return type: str
Returns: a string starting with ‘P’ describing the period
See: https://www.iso.org/fr/standard/70907.html

to_milliseconds(*, integral=None)¶

Return the total number of milliseconds in this Duration.

Parameters: integral (Optional[bool]) – If true, conversions into a larger time unit (e.g. Seconds to Minutes) will fail if the result is not an integer. Default: true
Return type: Union[int, float]
Returns: the value of this Duration expressed in Milliseconds.

to_minutes(*, integral=None)¶

Return the total number of minutes in this Duration.

Parameters: integral (Optional[bool]) – If true, conversions into a larger time unit (e.g. Seconds to Minutes) will fail if the result is not an integer. Default: true
Return type: Union[int, float]
Returns: the value of this Duration expressed in Minutes.

to_seconds(*, integral=None)¶

Return the total number of seconds in this Duration.

Parameters: integral (Optional[bool]) – If true, conversions into a larger time unit (e.g. Seconds to Minutes) will fail if the result is not an integer. Default: true
Return type: Union[int, float]
Returns: the value of this Duration expressed in Seconds.

to_string()¶

Returns a string representation of this Duration that is also a Token that cannot be successfully resolved.

This protects users against inadvertently stringifying a Duration object, when they should have called one of the to* methods instead.

Return type: str

unit_label()¶

Returns unit of the duration.

Return type: str
