template<typename>
class Geo::GeoString

STL string replacement.

Standard length doubling strategy allows for continued concatenation. Contains few of the algorithm functions (find_if, etc) but does have conversion from one string format to another. Also contains a Printf() function that creates a string from a standard C style format specifier, without the user having to know the maximum string length beforehand. There is no such thing as a NULL string representation; default constructor and construction from a NULL pointer both result in an empty string. If you must distinguish between empty and unset, use the Geo::Optional class.

Geo::GeoString< T >::~GeoString

public: ~GeoString()

Destructor.

void Geo::GeoString< T >::Clear

public: void Clear()

Clear the string.

s32 Geo::GeoString< T >::CopyTo

public: s32 CopyTo
(
T * buffer,
s32 maxCharsToCopy
) const

Copies the content of this string to the given raw character buffer.

Note this does not

copy the NUL terminator to the destination buffer.

Parameters

[in]	buffer	The destination buffer.
[in]	maxCharsToCopy	If this is less than the length of the string then only this many characters will be copied.

Returns

The number of characters copied.

bool Geo::GeoString< T >::Crop

public: bool Crop
(
s32 position
)

Terminates the string at the given position.

If position is less than the current length of the string it returns true, otherwise this is a no-op and returns false.

bool Geo::GeoString< T >::CropAfterLastChar

public: bool CropAfterLastChar
(
T c
)

This will remove the string beyond and including the last character specified if there is one.

If there isn't one it won't do anything.

Returns

True if the string was cropped.

bool Geo::GeoString< T >::CropBeforeLastChar

public: bool CropBeforeLastChar
(
T c
)

This will remove the string up to and including the last character specified if there is one.

If there isn't one it won't do anything.

Returns

True if the string was cropped.

void Geo::GeoString< T >::ForceLength

public: void ForceLength
(
s32 position
)

Directly sets the length of the string to the given value.

Useful for when the internal buffer is directly manipulated (after calling GetString()) and the stored length of the string needs to be kept in-sync.

static GeoString Geo::GeoString< T >::FromUtf8

public: GeoString FromUtf8
(
const char * utf8
)

Creates a new string of this format from a narrow string.

Geo::GeoString< T >::GeoString

public: GeoString()

Default constructor.

Geo::GeoString< T >::GeoString

public: GeoString
(
const T * str
)

Explicit constructor from a null-terminated array.

Geo::GeoString< T >::GeoString

public: GeoString
(
const T * str,
s32 n
)

Explicit constructor from an array of size n.

Geo::GeoString< T >::GeoString

public: GeoString
(
s32 capacity
)

Explicit constructor for an initial buffer length.

Geo::GeoString< T >::GeoString

public: GeoString
(
const GeoString & rhs
)

Copy constructor.

Geo::GeoString< T >::GeoString

public: GeoString
(
GeoString && rhs
)

Move constructor.

s32 Geo::GeoString< T >::GetCapacity

public: s32 GetCapacity() const

Returns the string capacity.

const T* Geo::GeoString< T >::GetCString

public: const T * GetCString() const

Returns a const raw pointer to the string.

s32 Geo::GeoString< T >::GetLength

public: s32 GetLength() const

Returns the length of the string.

T* Geo::GeoString< T >::GetString

public: T * GetString()

Returns a non-const raw pointer to the string.

bool Geo::GeoString< T >::IsEmpty

public: bool IsEmpty() const

Returns true if the string is empty.

Geo::GeoString< T >::operator GeoStringView< T >

public: operator GeoStringView< T >() const

Implicit conversion to string view.

T Geo::GeoString< T >::operator[]

public: T operator[]
(
s32 idx
) const

Element access operator. Do not use this to assign a terminator, or the string will very likely be corrupted.

bool Geo::GeoString< T >::operator<

public: bool operator<
(
const GeoString & rhs
) const

Comparison (required to use strings as keys in a map).

static GeoString Geo::GeoString< T >::Printf

public: GeoString Printf
(
const T * ,
...
)

Creates a string from a standard C style format specifier, without the user having to know the maximum string length beforehand.

bool Geo::GeoString< T >::SetCapacity

public: bool SetCapacity
(
s32 minLength
)

Set the string capacity (increase only).

GeoString Geo::GeoString< T >::Substring

public: GeoString Substring
(
Geo::s32 idxBegin,
Geo::s32 idxEnd
) const

Returns a subsection of the string.

Parameters

[in]	idxBegin	Index of first character of substring.
[in]	idxEnd	Index of 'one past end' of substring. May specify -1 to mean 'end of string'.

void Geo::GeoString< T >::Swap

public: void Swap
(
GeoString & other
)

Swap places with other.

GeoString<char> Geo::GeoString< T >::ToUtf8

public: GeoString< char > ToUtf8() const

Returns a new narrow string from this one.
