OffsetBase

Kotlin |Java

interface OffsetBase

androidx.ui.engine.geometry.OffsetBase

Known Direct Subclasses

Offset, Size

Offset	An immutable 2D floating-point offset.
Size	Holds a 2D floating-point size.

Base class for Size and Offset, which are both ways to describe a distance as a two-dimensional axis-aligned vector.

Abstract const constructor. This constructor enables subclasses to provide const constructors so that they can be used in const expressions.

The first argument sets the horizontal component, and the second the vertical component.

Summary

Public methods
open Boolean	`isFinite()` Whether both components are finite (neither infinite nor NaN).
open Boolean	`isGreaterOrEqThan(other: OffsetBase)` Greater-than-or-equal-to operator.
open Boolean	`isGreaterThan(other: OffsetBase)` Greater-than operator.
open Boolean	`isInfinite()` Returns true if either component is Float.POSITIVE_INFINITY, and false if both are finite (or negative infinity, or NaN).
open Boolean	`isLessOrEqThan(other: OffsetBase)` Less-than-or-equal-to operator.
open Boolean	`isLessThan(other: OffsetBase)` Less-than operator.

Properties
abstract Float	`dx`
abstract Float	`dy`

Public methods

isFinite

open fun isFinite(): Boolean

Whether both components are finite (neither infinite nor NaN).

isGreaterOrEqThan

open fun isGreaterOrEqThan(other: OffsetBase): Boolean

Greater-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.

This is a partial ordering. It is possible for two values to be neither less, nor greater than, nor equal to, another.

isGreaterThan

open fun isGreaterThan(other: OffsetBase): Boolean

Greater-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are bigger than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.

This is a partial ordering. It is possible for two values to be neither less, nor greater than, nor equal to, another.

isInfinite

open fun isInfinite(): Boolean

Returns true if either component is Float.POSITIVE_INFINITY, and false if both are finite (or negative infinity, or NaN).

This is different than comparing for equality with an instance that has both components set to Float.POSITIVE_INFINITY.

isLessOrEqThan

open fun isLessOrEqThan(other: OffsetBase): Boolean

Less-than-or-equal-to operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than or equal to the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.

This is a partial ordering. It is possible for two values to be neither less, nor greater than, nor equal to, another.

isLessThan

open fun isLessThan(other: OffsetBase): Boolean

Less-than operator. Compares an Offset or Size to another Offset or Size, and returns true if both the horizontal and vertical values of the left-hand-side operand are smaller than the horizontal and vertical values of the right-hand-side operand respectively. Returns false otherwise.

This is a partial ordering. It is possible for two values to be neither less, nor greater than, nor equal to, another.
