IsDefinedAndNotNull

▸ IsDefinedAndNotNull(value: any): boolean

Parameters:

  • value: any

Returns boolean

areCompatibleDataTypes

Returns true if two data types passed in parameters are compatible - so it's safe to copy the values between two expressions with these two types

▸ areCompatibleDataTypes(type1: DataType,type2: DataType): boolean

Parameters:

Returns boolean

assign

Copy the content of all objests passed in args parameters into target and returns the result NB: This function copies only the first level properties. For a deep copy please use assignDeep

▸ assign(target: any,args: any[]): any

Parameters:

  • target: any - the target object
  • args: any[] - an array of the source objects

Returns any

assignDeep

Copy the content of all objests passed in args parameters into target and returns the result NB: This function make a deep copy - so assignDeep will be called recursively for all object properties on the first level.

Parameters:

  • target: any - the target object
  • sources: any[] - an array of the source objects

Returns any
