Detailed Description

A uniqued constant string class.

Provides an efficient way to store strings as uniqued strings. After the strings are uniqued, finding strings that are equal to one another is very fast as just the pointers need to be compared. It also allows for many common strings from many different sources to be shared to keep the memory footprint low.

No reference counting is done on strings that are added to the string pool, once strings are added they are in the string pool for the life of the program.

Constructor & Destructor Documentation

ConstString() [1/4]

lldb_private::ConstString::ConstString ( )

default

Default constructor.

Initializes the string to an empty string.

Referenced by MemorySize().

ConstString() [2/4]

ConstString::ConstString ( llvm::StringRef  s )

explicit

Definition at line 217 of file ConstString.cpp.

ConstString() [3/4]

ConstString::ConstString ( const char *  cstr )

explicit

Construct with C String value.

Constructs this object with a C string by looking to see if the C string already exists in the global string pool. If it doesn't exist, it is added to the string pool.

Parameters

[in]

cstr

A NULL terminated C string to add to the string pool.

Definition at line 211 of file ConstString.cpp.

ConstString() [4/4]

ConstString::ConstString ( const char *  cstr, size_t  max_cstr_len  )

explicit

Construct with C String value with max length.

Constructs this object with a C string with a length. If max_cstr_len is greater than the actual length of the string, the string length will be truncated. This allows substrings to be created without the need to NULL terminate the string as it is passed into this function.

Parameters

[in]	cstr	A pointer to the first character in the C string. The C string can be NULL terminated in a buffer that contains more characters than the length of the string, or the string can be part of another string and a new substring can be created.
[in]	max_cstr_len	The max length of cstr. If the string length of cstr is less than max_cstr_len, then the string will be truncated. If the string length of cstr is greater than max_cstr_len, then only max_cstr_len bytes will be used from cstr.

Member Function Documentation

AsCString()

const char * lldb_private::ConstString::AsCString ( const char *  value_if_empty = nullptr ) const

inline

Get the string value as a C string.

Get the value of the contained string as a NULL terminated C string value.

If value_if_empty is nullptr, then nullptr will be returned.

Returns

Returns value_if_empty if the string is empty, otherwise the C string value contained in this object.

Clear()

void lldb_private::ConstString::Clear ( )

inline

Clear this object's state.

Clear any contained string and reset the value to the empty string value.

Compare()

int ConstString::Compare ( ConstString  lhs, ConstString  rhs, const bool  case_sensitive = true  )

static

Compare two string objects.

Compares the C string values contained in lhs and rhs and returns an integer result.

NOTE: only call this function when you want a true string comparison. If you want string equality use the, use the == operator as it is much more efficient. Also if you want string inequality, use the != operator for the same reasons.

Parameters

[in]	lhs	The Left Hand Side const ConstString object reference.
[in]	rhs	The Right Hand Side const ConstString object reference.
[in]	case_sensitive	Case sensitivity of compare. If true, case sensitive compare will be performed, otherwise character case will be ignored

Returns

-1 if lhs < rhs, 0 if lhs == rhs, 1 if lhs > rhs

Dump()

void ConstString::Dump	(	Stream *	s,
		const char *	value_if_empty = nullptr
	)		const

Dump the object description to a stream.

Dump the string value to the stream s. If the contained string is empty, print value_if_empty to the stream instead. If value_if_empty is nullptr, then nothing will be dumped to the stream.

Parameters

[in]	s	The stream that will be used to dump the object description.
[in]	value_if_empty	The value to dump if the string is empty. If nullptr, nothing will be output to the stream.

(

Stream *

s

)

const

Dump the object debug description to a stream.

Equals()

bool ConstString::Equals ( ConstString  lhs, ConstString  rhs, const bool  case_sensitive = true  )

static

Equal to operator.

Returns true if this string is equal to the string in rhs. If case sensitive equality is tested, this operation is very fast as it results in a pointer comparison since all strings are in a uniqued in a global string pool.

Parameters

[in]	lhs	The Left Hand Side const ConstString object reference.
[in]	rhs	The Right Hand Side const ConstString object reference.
[in]	case_sensitive	Case sensitivity. If true, case sensitive equality will be tested, otherwise character case will be ignored

Returns

true if this object is equal to rhs, false otherwise.

GetCString()

const char * lldb_private::ConstString::GetCString ( ) const

inline

Get the string value as a C string.

Get the value of the contained string as a NULL terminated C string value. Similar to the ConstString::AsCString() function, yet this function will always return nullptr if the string is not valid. So this function is a direct accessor to the string pointer value.

Returns

Returns nullptr the string is invalid, otherwise the C string value contained in this object.

GetLength()

size_t ConstString::GetLength

(

)

const

Get the length in bytes of string value.

The string pool stores the length of the string, so we can avoid calling strlen() on the pointer value with this function.

Returns

Returns the number of bytes that this string occupies in memory, not including the NULL termination byte.

GetMangledCounterpart()

bool ConstString::GetMangledCounterpart

(

ConstString &

counterpart

)

const

Retrieve the mangled or demangled counterpart for a mangled or demangled ConstString.

Object files and debug symbols often use mangled string to represent the linkage name for a symbol, function or global. The string pool can efficiently store these values and their counterparts so when we run into another instance of a mangled name, we can avoid calling the name demangler over and over on the same strings and then trying to unique them.

Parameters

[in]

counterpart

A reference to a ConstString object that might get filled in with the demangled/mangled counterpart.

Returns

/b True if counterpart was filled in with the counterpart /b false otherwise.

operator!=() [1/2]

bool lldb_private::ConstString::operator!= ( const char *  rhs ) const

inline

Not equal to operator against a non-ConstString value.

Returns true if this string is not equal to the string in rhs. This overload is usually slower than comparing against a ConstString value. However, if the rhs string not already a ConstString and it is impractical to turn it into a non-temporary variable, then this overload is faster.

Parameters

[in]

rhs

Another string object to compare this object to.

Returns

true if this object is not equal to rhs, false otherwise.

Definition at line 164 of file ConstString.h.

operator!=() [2/2]

bool lldb_private::ConstString::operator!= ( ConstString  rhs ) const

inline

Not equal to operator.

Returns true if this string is not equal to the string in rhs. This operation is very fast as it results in a pointer comparison since all strings are in a uniqued in a global string pool.

Parameters

[in]

rhs

Another string object to compare this object to.

Returns

true if this object is not equal to rhs. false if this object is equal to rhs.

SetCString()

void ConstString::SetCString

(

const char *

cstr

)

Set the C string value.

Set the string value in the object by uniquing the cstr string value in our global string pool.

If the C string already exists in the global string pool, it finds the current entry and returns the existing value. If it doesn't exist, it is added to the string pool.

Parameters

[in]

cstr

A NULL terminated C string to add to the string pool.

SetCStringWithLength()

void ConstString::SetCStringWithLength	(	const char *	cstr,
		size_t	cstr_len
	)

Set the C string value with length.

Set the string value in the object by uniquing cstr_len bytes starting at the cstr string value in our global string pool. If trim is true, then cstr_len indicates a maximum length of the CString and if the actual length of the string is less, then it will be trimmed.

If the C string already exists in the global string pool, it finds the current entry and returns the existing value. If it doesn't exist, it is added to the string pool.

Parameters

[in]	cstr	A NULL terminated C string to add to the string pool.
[in]	cstr_len	The maximum length of the C string.

SetStringWithMangledCounterpart()

void ConstString::SetStringWithMangledCounterpart	(	llvm::StringRef	demangled,
		ConstString	mangled
	)

Set the C string value and its mangled counterpart.

Object files and debug symbols often use mangled string to represent the linkage name for a symbol, function or global. The string pool can efficiently store these values and their counterparts so when we run into another instance of a mangled name, we can avoid calling the name demangler over and over on the same strings and then trying to unique them.

Parameters

[in]	demangled	The demangled string to correlate with the mangled name.
[in]	mangled	The already uniqued mangled ConstString to correlate the soon to be uniqued version of demangled.

SetTrimmedCStringWithLength()

void ConstString::SetTrimmedCStringWithLength	(	const char *	cstr,

	)

Set the C string value with the minimum length between fixed_cstr_len and the actual length of the C string.

This can be used for data structures that have a fixed length to store a C string where the string might not be NULL terminated if the string takes the entire buffer.
