attributeGroupSpec.attributes : Array.<AttributeSpec>

Kind: instance property of AttributeGroupSpec
Read only: true

attributeGroupSpec.isAttributeGroupSpec : boolean

Kind: instance property of AttributeGroupSpec
Read only: true

attributeGroupSpec.getAttributeByName(name) ⇒ AttributeSpec | undefined

Kind: instance method of AttributeGroupSpec

Param	Type
name	string

attributeGroupSpec.getAttributeIndexByName(name) ⇒ number

Kind: instance method of AttributeGroupSpec
Returns: number - -1 if not found

Param	Type
name	string

attributeGroupSpec.addMany(attributes)

Kind: instance method of AttributeGroupSpec
Throws:

• Error if any there are any name collisions

Param	Type
