Methods

Cast

Cast<T1, T2>(this, type): T1
Casts this object to the specified type. Throws error on failure.
Type Parameters
- T1
  The target type of the cast.
- T2
  The type of the object to cast.
Parameters
- this: T2
- type: TypeRef<T1>
  The type to cast to.
Returns T1
Inherited from ReplaceValuesBaseTransformation.Cast

Equals

Equals(obj): boolean
Determines whether the specified object is equal to the current object.
Parameters
- obj: any
  The object to compare with the current object.
Returns boolean
true if the specified object is equal to the current object; otherwise, false.

Inherited from ReplaceValuesBaseTransformation.Equals

GetHashCode

GetHashCode(): number
Serves as the default hash function.

Returns number
A hash code for the current object.

Inherited from ReplaceValuesBaseTransformation.GetHashCode

ToString

ToString(): string
Returns a string that represents the current object.

Returns string
A string that represents the current object.

Inherited from ReplaceValuesBaseTransformation.ToString

TryCast

TryCast<T1, T2>(this, type): null | T1
Casts this object to the specified type. Returns null on failure.
Type Parameters
- T1
  The target type of the cast.
- T2
  The type of the object to cast.
Parameters
- this: T2
- type: TypeRef<T1>
  The type to cast to.
Returns null | T1
Inherited from ReplaceValuesBaseTransformation.TryCast

`Static`Equals

Equals(objA, objB): boolean
Determines whether the specified object instances are considered equal.
Parameters
- objA: any
  The first object to compare.
- objB: any
  The second object to compare.
Returns boolean
true if the objects are considered equal; otherwise, false. If both objA and objB are null, the method returns true.
