Detailed Description

A JavaScript symbol (ECMA-262 edition 6)

Definition at line 586 of file v8-primitive.h.

Member Function Documentation

◆ Cast()

static V8_INLINE Symbol * Cast ( Data *  data)
inlinestatic

Definition at line 629 of file v8-primitive.h.

◆ Description()

Local< Value > Description ( Isolate *  isolate) const

Returns the description string of the symbol, or undefined if none.

◆ For()

static Local< Symbol > For ( Isolate *  isolate,
Local< String >  description 
)
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 descriptions used as keys. To minimize the potential for clashes, use qualified names as keys.

◆ ForApi()

static Local< Symbol > ForApi ( Isolate *  isolate,
Local< String >  description 
)
static

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

◆ GetAsyncIterator()

static Local< Symbol > GetAsyncIterator ( Isolate *  isolate)
static

◆ GetHasInstance()

static Local< Symbol > GetHasInstance ( Isolate *  isolate)
static

◆ GetIsConcatSpreadable()

static Local< Symbol > GetIsConcatSpreadable ( Isolate *  isolate)
static

◆ GetIterator()

static Local< Symbol > GetIterator ( Isolate *  isolate)
static

◆ GetMatch()

static Local< Symbol > GetMatch ( Isolate *  isolate)
static

◆ GetReplace()

static Local< Symbol > GetReplace ( Isolate *  isolate)
static

◆ GetSearch()

static Local< Symbol > GetSearch ( Isolate *  isolate)
static

◆ GetSplit()

static Local< Symbol > GetSplit ( Isolate *  isolate)
static

◆ GetToPrimitive()

static Local< Symbol > GetToPrimitive ( Isolate *  isolate)
static

◆ GetToStringTag()

static Local< Symbol > GetToStringTag ( Isolate *  isolate)
static

◆ GetUnscopables()

static Local< Symbol > GetUnscopables ( Isolate *  isolate)
static

◆ New()

static Local< Symbol > New ( Isolate *  isolate,
Local< String >  description = Local< String >() 
)
static

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