Detailed Description

A JavaScript symbol (ECMA-262 edition 6)

Definition at line 3034 of file v8.h.

Member Function Documentation

§ Cast()

Symbol * v8::Symbol::Cast ( v8::Value value)
static

Definition at line 10166 of file v8.h.

§ For()

Local< Symbol > v8::Symbol::For ( Isolate isolate,
Local< String name 
)
static

Access global symbol registry. Note that symbols created this way are never collected, so they should only be used for statically fixed properties. Also, there is only one global name space for the names used as keys. To minimize the potential for clashes, use qualified names as keys.

Definition at line 7973 of file api.cc.

Here is the call graph for this function:

§ ForApi()

Local< Symbol > v8::Symbol::ForApi ( Isolate isolate,
Local< String name 
)
static

Retrieve a global symbol. Similar to |For|, but using a separate registry that is not accessible by (and cannot clash with) JavaScript code.

Definition at line 7981 of file api.cc.

Here is the call graph for this function:

§ GetHasInstance()

static Local<Symbol> v8::Symbol::GetHasInstance ( Isolate isolate)
static

§ GetIsConcatSpreadable()

static Local<Symbol> v8::Symbol::GetIsConcatSpreadable ( Isolate isolate)
static

§ GetIterator()

static Local<Symbol> v8::Symbol::GetIterator ( Isolate isolate)
static

§ GetMatch()

static Local<Symbol> v8::Symbol::GetMatch ( Isolate isolate)
static

§ GetReplace()

static Local<Symbol> v8::Symbol::GetReplace ( Isolate isolate)
static

§ GetSearch()

static Local<Symbol> v8::Symbol::GetSearch ( Isolate isolate)
static

§ GetSplit()

static Local<Symbol> v8::Symbol::GetSplit ( Isolate isolate)
static

§ GetToPrimitive()

static Local<Symbol> v8::Symbol::GetToPrimitive ( Isolate isolate)
static

§ GetToStringTag()

static Local<Symbol> v8::Symbol::GetToStringTag ( Isolate isolate)
static

§ GetUnscopables()

static Local<Symbol> v8::Symbol::GetUnscopables ( Isolate isolate)
static

§ Name()

Local< Value > v8::Symbol::Name ( ) const

Returns the print name string of the symbol, or undefined if none.

Definition at line 5894 of file api.cc.

Here is the call graph for this function:

§ New()

Local< Symbol > v8::Symbol::New ( Isolate isolate,
Local< String name = Local<String>() 
)
static

Create a symbol. If name is not empty, it will be used as the description.

Definition at line 7963 of file api.cc.
