Property Utilities

ethers . utils . checkProperties( object , check ) => void

Checks that object only contains properties included in check, and throws INVALID_ARGUMENT if not.

ethers . utils . deepCopy( anObject ) => any

Creates a recursive copy of anObject. Frozen (i.e. and other known immutable) objects are copied by reference.

ethers . utils . defineReadOnly( anObject , name , value ) => void

Uses the Object.defineProperty method to set a read-only property on an object.

ethers . utils . getStatic( aConstructor , key ) => any

Recursively check for a static method key on an inheritance chain from aConstructor to all ancestors.

This is used to mimic behaviour in other languages where this in a static method will also search ancestors.

ethers . utils . resolveProperties( anObject ) => Promise< any >

Retruns a Promise which resolves all child values on anObject.

ethers . utils . shallowCopy( anObject ) => any

Returns a shallow copy of anObject. This is the same as using Object.assign({ }, anObject).
