struct FSchema

Remarks

Observation Schema

This object allows you to construct a description of the kind of observations you might want to provide as input to a policy. Internally this object contains a pool of individual elements. This allows them to be constructed performantly and in a cache efficient way. This object is therefore required to access any data about the individual observation elements that are created.

GetTag ( const FSchemaElement Element
)

 Gets the tag of the given element.
Public function Const EType

GetType ( const FSchemaElement Element
)

 Gets the type of the given element.
Public function Const bool

IsEmpty ()

 Checks if the given schema is empty of elements.
Public function Const bool

IsValid ( const FSchemaElement Element
)
