Functions

  Type Name Description
Public function Virtual Const bool Returns true if the element, in its current phase can be executed only from the main thread
Public function Const void

DebugDisplay ( FPCGContext* Context
)

 Note: the following methods must be called from the main thread
Protected function Virtual Const void Passes through data when the element is Disabled.
Public function Const bool

Execute ( FPCGContext* Context
)

 Public function that executes the element on the appropriately created context.
Protected function Const bool Core execution method for the given element. Will be called until it returns true.
Public function Virtual Const void

GetDependenciesCrc ( const FPCGDataCollection& InInput,
const UPCGSettings* InSettings,
UPCGComponent* InComponent,
FPCGCrc& OutCrc
)

 Calculate a Crc that provides a receipt for the input data that can be paired with output data from the cache.
Public function FPCGContext *

Initialize ( const FPCGDataCollection& InputData,
TWeakObjectPtr< UPCGComponent > SourceComponent,
const UPCGNode* Node
)

 Creates a custom context object paired to this element
Public function Virtual Const bool

IsCacheable ( const UPCGSettings* InSettings
)

 Returns true if the node can be cached (e.g. does not create artifacts & does not depend on untracked data
Public function Const bool

IsCacheableInstance ( const UPCGSettingsInterface* InSettingsInterface
)

 Returns true if the node can be cached - also checks for instance flags, if any.
Protected function Virtual Const bool Controls whether an element can skip its execution wholly when the input data has the cancelled tag
Protected function Virtual Const bool

IsPassthrough ( const UPCGSettings* InSettings
)

 Used to specify that the element passes through the data without any manipulation - used to correct target pins, etc.
Protected function Const void

PostExecute ( FPCGContext* Context
)

 This function will be called once and once only, at the end of an execution
Protected function Const void

PreExecute ( FPCGContext* Context
)

 This function will be called once and once only, at the beginning of an execution
Protected function Virtual Const bool The prepare data phase is one where it is more likely to be able to multithread
Public function Virtual Const bool Whether to do a 'deep' fine-grained CRC of the output data to pass to downstream nodes.
Protected function Virtual Const bool
