protected abstract RenderResult |
doResolve()
Overridden by generated subclasses to implement lazy detachable resolution.
|
RenderResult |
renderAndResolve(LoggingAdvisingAppendable appendable,
boolean isLast)
Renders this value to the given
LoggingAdvisingAppendable,
possibly partially. |
SoyValue |
resolve()
Usually, this method is a no-op that simply returns this object.
|
RenderResult |
status()
Returns
RenderResult.done() if the value provider can be resolved
without blocking on a future. |

SoyValueProviderRenderResult.done() if the value provider can be resolved
without blocking on a future. Otherwise, returns a RenderResult that holds the future.
Note, once this method returns RenderResult.done() all future calls must also return
RenderResult.done().

This should render the exact same content as resolve().render(Appendable) but may
optionally detach part of the way through rendering. Note, this means that this method is
stateful and if it returns something besides RenderResult.done() then the next
call to this method will resume rendering from the previous point.

Used as a hint to implementations to not optimize for later calls (for example, by storing
render results in a buffer for faster re-renders). The value of this parameter should not
affect behavior of this method, only performance.RenderResult that describes whether or not rendering completed. If the
returned result is not done, then to complete rendering you
must call this method again.IOException - If the appendable throws an IOExceptionprotected abstract RenderResult doResolve()
