FMetaSoundFrontendDocumentBuilder

Builder used to support dynamically generating MetaSound documents at runtime.

API > API/Plugins > API/Plugins/MetasoundFrontend

Builder used to support dynamically generating MetaSound documents at runtime. Builder contains caches that speed up common search and modification operations on a given document, which may result in slower performance on construction, but faster manipulation of its managed document. The builder's managed copy of a document is expected to not be modified by any external system to avoid cache becoming stale.

)

   MetasoundFrontendDocumentBuilder.h  

const FMetasoundFrontendClass * AddDependency ( FMetasoundFrontendClass NewDependency
)

 Adds new dependency to MetaSound. Typically not necessary to call directly as dependencies are added automatically via registry when nodes are added, and can be removed when no longer referenced (see 'RemoveUnusedDependencies`). MetasoundFrontendDocumentBuilder.h  

void AddEdge ( FMetasoundFrontendEdge&& InNewEdge,
const FGuid* InPageID
)

   MetasoundFrontendDocumentBuilder.h

)

   MetasoundFrontendDocumentBuilder.h  

const FMetasoundFrontendNode * AddGraphInput ( FMetasoundFrontendClassInput ClassInput,
const FGuid* InPageID
)

 Adds Graph Input to document, which in turn adds a referencing input node to ALL pages. If valid PageID is provided, returns associated page's node pointer. If none provided, returns node pointer to node for the builder's currently set build page ID (see 'GetBuildPageID'). MetasoundFrontendDocumentBuilder.h  

const FMetasoundFrontendNode * AddGraphNode ( const FMetasoundFrontendGraphClass& InClass,
FGuid InNodeID,

const FMetasoundFrontendNode * AddGraphOutput ( FMetasoundFrontendClassOutput ClassOutput,
const FGuid* InPageID
)

 Adds Graph Output to document, which in turn adds a referencing output node to ALL pages. If valid PageID is provided, returns associated page's node pointer. If none provided, returns node pointer to node for the builder's currently set build page ID (see 'GetBuildPageID'). MetasoundFrontendDocumentBuilder.h

bool AddInterface ( FName InterfaceName,
bool bAddUserModifiableInterfaceOnly,
const FMetaSoundFrontendDocumentBuilder* ReferenceBuilder
)

 Internal AddInterface call for use in rebuild preset root graph If bAddUserModifiableInterfaceOnly is true, only user modifiable interfaces can be added (see FMetasoundFrontendInterfaceUClassOptions) Reference builder is used to copy node ids for added members so they aren't just regenerated with NewGuid. MetasoundFrontendDocumentBuilder.h  

bool AddInterface ( FName InterfaceName
)

 Adds an interface and associated inputs and outputs. MetasoundFrontendDocumentBuilder.h

bool CanAddEdge ( const FMetasoundFrontendEdge& InEdge,
const FGuid* InPageID
) const

Metasound::Frontend::EAutoUpdateEligibility CanAutoUpdate ( const FGuid& InNodeID,
const FGuid* InPageID
) const

 Returns whether the node is eligible for auto-updating and reason for eligibility (i.e. has undergone minor version revision, node update transform found, or the interface has changed, but no higher major revision is available).

bool SetBuildPageID ( const FGuid& InBuildPageID,
bool bBroadcastDelegate
)

 Sets the builder's targeted paged graph ID to the given ID if it exists. Returns true if the builder is already targeting the given ID or if it successfully found a page implementation with the given ID and was able to switch to it, false if not. Swapping the targeted build graph ID clears the local cache, so swapping frequently can induce cache thrashing. BroadcastDelegate should always be true unless dealing with the controller API (exposed as a mechanism for mutating via controllers while deprecating. Option will be removed in a future build).
