Member Function Documentation

Dispose()

virtual void Dispose ( )

inlineprotectedvirtual

Internally V8 will call this Dispose method when the external string resource is no longer needed. The default implementation will use the delete operator. This method can be overridden in subclasses to control how allocated external string resources are disposed.

Definition at line 2774 of file v8.h.

IsCacheable()

virtual bool IsCacheable ( ) const

inlinevirtual

If a string is cacheable, the value returned by ExternalStringResource::data() may be cached, otherwise it is not expected to be stable beyond the current top-level task.

Definition at line 2763 of file v8.h.

Lock()

virtual void Lock ( ) const

inlineprotectedvirtual

For a non-cacheable string, the value returned by |ExternalStringResource::data()| has to be stable between |Lock()| and |Unlock()|, that is the string must behave as is |IsCacheable()| returned true.

These two functions must be thread-safe, and can be called from anywhere. They also must handle lock depth, in the sense that each can be called several times, from different threads, and unlocking should only happen when the balance of Lock() and Unlock() calls is 0.

operator=()

void operator= ( const ExternalStringResourceBase &  )

protecteddelete

Unlock()

virtual void Unlock ( ) const

inlineprotectedvirtual

Unlocks the string.
