Parameters:

value - a possibly wrapped value

Returns:

a new StaticValueResolver pointing to the unwrapped value

resolve

public T resolve(ValueResolvingContext context)
          throws org.mule.runtime.api.exception.MuleException

Resolves a value from the given event

Specified by:

resolve in interface ValueResolver<T>

Parameters:

context - the context for the current resolution attempt

Returns:

a resolved value

Throws:

org.mule.runtime.api.exception.MuleException - if the resolution of the value fails

isDynamic

public boolean isDynamic()

Description copied from interface: ValueResolver

Returns false if subsequent invocations to ValueResolver.resolve(ValueResolvingContext) will return the same value. Notice that if it returns true, then it might return different values per invocation but that's not guaranteed.

Specified by:

Returns:

false
