Constructor & Destructor Documentation

◆ FPathTree()

FPathTree::FPathTree ( )

Member Function Documentation

◆ CachePath()

bool FPathTree::CachePath	(	FName	Path,
		TFunctionRef< void(FName)>	OnPathAdded
	)

Adds the specified path to the tree, creating nodes as needed and calling OnPathAdded for any new paths added. Returns true if the specified path was actually added (as opposed to already existed)

◆ EnsureAdditionalCapacity()

void FPathTree::EnsureAdditionalCapacity ( int32 NumNewPaths )

Reserve extra space for the expected number of paths that will be added in future. Count is added to the current number of stored paths and not any previous reservation.

◆ EnumerateAllPaths()

void FPathTree::EnumerateAllPaths ( TFunctionRef< bool(FName)> Callback ) const

Enumerate all of the paths we know about

◆ EnumerateSubPaths()

bool FPathTree::EnumerateSubPaths	(	FName	BasePath,
		TFunctionRef< bool(FName)>	Callback,
		bool	bRecurse = `true`
	)		const

Recursively enumerates all child paths from the specified base path relative to this node

◆ GetAllocatedSize()

SIZE_T FPathTree::GetAllocatedSize ( void ) const

inline

◆ GetAllPaths()

bool FPathTree::GetAllPaths ( TSet< FName > & OutPaths ) const

Get all of the paths we know about

◆ GetSubPaths()

bool FPathTree::GetSubPaths	(	FName	BasePath,
		TSet< FName > &	OutPaths,
		bool	bRecurse = `true`
	)		const

Recursively gathers all child paths from the specified base path relative to this node

◆ NormalizePackagePath()

FName FPathTree::NormalizePackagePath ( FName In )

static

Normalize the given PackagePath (/Game/SubDir) by removing a trailing slash if it exists.

◆ NumPaths()

int32 FPathTree::NumPaths ( ) const

inline

◆ PathExists()

bool FPathTree::PathExists ( FName Path ) const

Checks whether the given path is one that we know about

◆ RemovePath()

bool FPathTree::RemovePath	(	FName	Path,
		TFunctionRef< void(FName)>	OnPathRemoved
	)

Removes the specified path from the tree, calling OnPathRemoved for any existing paths removed. Returns true if the path was found and removed.

◆ Shrink()

void FPathTree::Shrink ( )

Shrinks the internal structures reducing the memory they use.
