Determine whether this function instance is capable of operating on the specified target. It is only valid to call this with a type such that {@code target.getType()} is compatible with the valuereturned by {@link #getTargetType}, its behavior is otherwise undefined. It is always valid to return true and validate the target during the call to {@link #getResults}, however this is used during the dependency graph build as a fast check to add or exclude the function from the set to be considered to satisfy a requirement. If a function cannot apply to a target it must not throw an exception; throwing an exception (instead of returning false) should be used in serious cases only (for example the target is generally illegal or inconsistent) as it will abort the dependency graph build for the target. @param context the compilation context with view-specific parameters and configurations @param target the target for which calculation is desired @return true if this function can produce results for the specified target, false otherwise
