Member Function Documentation

◆ CanSeeDefinition()

bool uLang::CAstPackage::CanSeeDefinition ( const CDefinition &  Definition) const

◆ GetErrorDesc()

virtual CUTF8String uLang::CAstPackage::GetErrorDesc ( ) const
inlineoverridevirtual

Implements uLang::CAstNode.

◆ GetNodeType()

virtual EAstNodeType uLang::CAstPackage::GetNodeType ( ) const
inlineoverridevirtual

Implements uLang::CAstNode.

◆ VisitChildren()

virtual void uLang::CAstPackage::VisitChildren ( SAstVisitor &  Visitor) const
inlineoverridevirtual

Iterates over this AST node's direct children, calling Visitor.Visit for each child.

Reimplemented from uLang::CAstNode.

◆ VisitImmediates()

void uLang::CAstPackage::VisitImmediates ( SAstVisitor &  Visitor) const
overridevirtual

Iterates over this AST node's immediate fields, calling Visitor.VisitImmediate for each immediate field.

Reimplemented from uLang::CAstNode.

◆ _bAllowNative

bool uLang::CAstPackage::_bAllowNative

◆ _bTreatModulesAsImplicit

◆ _CompilationUnit

CAstCompilationUnit* uLang::CAstPackage::_CompilationUnit = nullptr

◆ _Dependencies

◆ _EffectiveVerseVersion

uint32_t uLang::CAstPackage::_EffectiveVerseVersion

◆ _Name

CUTF8String uLang::CAstPackage::_Name

◆ _NumPersistentVars

int32_t uLang::CAstPackage::_NumPersistentVars = 0

◆ _Role

EPackageRole uLang::CAstPackage::_Role

◆ _RootModule

CModulePart* uLang::CAstPackage::_RootModule = nullptr

◆ _UploadedAtFNVersion

uint32_t uLang::CAstPackage::_UploadedAtFNVersion = VerseFN::UploadedAtFNVersion::Latest

This allows us to determine when a package was uploaded for a given Fortnite release version. It is a HACK that conditionally enables/disables behaviour in the compiler in order to support previous mistakes allowed to slip through in previous Verse langauge releases but now need to be supported for backwards compatability. When we can confirm that all Fortnite packages that are currently uploaded are beyond this version being used in all instances of the codebase, this can then be removed.

◆ _UsedDependencies

TArray<const CAstPackage*> uLang::CAstPackage::_UsedDependencies

◆ _VersePath

◆ _VerseScope
