Attributes

Remarks

Produces a method handle of the requested return type which returns the given constant value every time it is invoked.

Before the method handle is returned, the passed-in value is converted to the requested type. If the requested type is primitive, widening primitive conversions are attempted, else reference conversions are attempted.

The returned method handle is equivalent to identity(type).bindTo(value).
