Detailed Description

A data item with which we can test lists and trees. It supports having children and having a name.

Member Function Documentation

AddChild()

void FTestData::AddChild ( TSharedRef< FTestData >  InChild )

inline

Add a child to this test data item.

Parameters

InChild

A reference to the child being added

BinaryProbability()

static bool FTestData::BinaryProbability ( int32  Level )

inlinestatic

Returns

true or false with decreasing probability of true for higher values of Level. Level < 0 is always true. Level = 0 is 50.0% chance of true. Level = 1 is 25.0% chance of true. Level = 2 is 12.5% chance of true. Level = N is 1/(2^Level) chance of true.

GenerateChildren()

static int32 FTestData::GenerateChildren ( TSharedRef< FTestData >  MakeChildrenForMe, int32  DescendantsLeftToMake, int32  NestingDepth  )

inlinestatic

Recursively add a bunch of descendants to this node. TotalDescendants is how many descendants we should add before we stop.

Parameters

MakeChildrenForMe	The node to which to add children
DescendantsLeftToMake	How many descendants we still need to make
NestingDepth	Track the nesting depth to prevent super-deep nesting

Returns

How many descendants we still need to make after this function ran.

GetChildren()

void FTestData::GetChildren ( TArray< TSharedPtr< FTestData > > &  OutChildren )

inline

Populate the OutChildren array with this data item's children.

Parameters

OutChildren

GetName()

const FText & FTestData::GetName ( ) const

inline

Returns

the name of this data item

GetNumber()

float FTestData::GetNumber ( ) const

inline

Returns

the dummy number value

InsertRecursive()

static bool FTestData::InsertRecursive ( TArray< TSharedPtr< FTestData > > &  InsertInto, const TSharedRef< FTestData > &  ItemToInsert, const TSharedRef< FTestData > &  TargetItem, EItemDropZone  RelativeLocation  )

inlinestatic

Recursively look for TargetItem in InsertInto and any of the descendants. Insert ItemToInsert relative to the target. Relative positioning dictated by RelativeLocation.

Returns

true when successful.

Make()

static TSharedRef< FTestData > FTestData::Make ( const FText &  ChildName )

inlinestatic

MakeRandomItemHeight()

static float FTestData::MakeRandomItemHeight ( )

inlinestatic

RemoveRecursive()

static bool FTestData::RemoveRecursive ( TArray< TSharedPtr< FTestData > > &  RemoveFrom, const TSharedPtr< FTestData > &  ItemToRemove  )

inlinestatic

Recursively look for ItemToRemove in RemoveFrom and any of the descendants, and remove ItemToRemove.

Returns

true when successful.

SetName()

void FTestData::SetName ( const FText &  InNewName )

inline

Set this data node's name

Parameters

InNewName

The new name to assign to this data item.

SetNumber()

void FTestData::SetNumber ( float  NewValue )

inline

Parameters

NewValue

The new dummy value
