struct SelfHostedWrapper {
void *unused;
const char *funname;
};
const char *name;
int8 tinyid; // Obsolete since JSAPI 31
uint8_t flags;
union {
JSNativeWrapper native;
SelfHostedWrapper selfHosted;

};
Name | Type | Description |
---|---|---|
name | const char * | Name to assign the property. |
tinyid | int8 | Obsolete since JSAPI 31 Unique ID number for the property to aid in resolving getProperty and setProperty method calls. This value should be zero if you are not using tinyIDs (i.e. the getter/setter function is only used by one property). |
flags | uint8_t | The bitwise OR of any number of Property attributes. |
getter | JSNativeWrapper or SelfHostedWrapper | Getter method for the property. |
setter | JSNativeWrapper or SelfHostedWrapper | Setter method for the property. If a property is read-only, its setter is never called. |
