FilterArray()

void FilterArray	(	TArray< AActor >	TargetArray,
		TSubclassOf< AActor >	FilterClass,
		TArray< AActor > &	FilteredArray )

Filter an array based on a Class derived from Actor.

Parameters

TargetArray	The array to filter from *
FilterClass	The Actor sub-class type that acts as the filter, only objects derived from it will be returned. *

Returns

An array containing only those objects which are derived from the class specified.

SortByteArray()

void SortByteArray	(	TArray< uint8 > &	TargetArray,
		bool	bStableSort = false,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of bytes.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
SortOrder	If the array should be sorted in ascending or descending order.

SortFloatArray()

void SortFloatArray	(	TArray< float > &	TargetArray,
		bool	bStableSort = false,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of doubles.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
SortOrder	If the array should be sorted in ascending or descending order.

SortInt64Array()

void SortInt64Array	(	TArray< int64 > &	TargetArray,
		bool	bStableSort = false,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of 64-bit integers.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
SortOrder	If the array should be sorted in ascending or descending order.

SortIntArray()

void SortIntArray	(	TArray< int > &	TargetArray,
		bool	bStableSort = false,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of integers.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
SortOrder	If the array should be sorted in ascending or descending order.

SortNameArray()

void SortNameArray	(	TArray< FName > &	TargetArray,
		bool	bStableSort = false,
		bool	bLexicalSort = true,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of FNames.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
bLexicalSort	If the names should be sorted based on the string value of the name rather than the comparison index. This is slower when enabled.
SortOrder	If the array should be sorted in ascending or descending order.

SortStringArray()

void SortStringArray	(	TArray< FString > &	TargetArray,
		bool	bStableSort = false,
		EArraySortOrder	SortOrder = EArraySortOrder :: Ascending )

Sorts an array of strings alphabetically.

Parameters

TargetArray	The array to sort.
bStableSort	If a stable sort should be used. This preserves the order of identical elements, but is slower.
SortOrder	If the array should be sorted in ascending or descending order.
