The

The "reduced" content type, derived from the tuple type

- def apply(stack: IndexedSeq[Item], offset: Int, avail: Int): Option[A]
The main context match method.
The main context match method.
Inspects the elements in the XML "tag stack", which is essentially a
List[StartElement], but for performance reasons is represented as an array with an "offset" index and a number of available elements from that offset. If the elements correspond to a context value ofA, the implementation must then pass the remaining elements of the stack to thenextmatcher, i.e. by callingnext(stack, offset + numConsumed, avail - numConsumed).The difference between this method and
applyChainedis the lack of thenextparameter; in this method, the current matcher is assumed to be the end of the chain.- stack
A reference to the complete XML "tag stack". Note that the responsibility of this method is limited to a *slice* of this value, as defined by
offsetandavail.- offset
The index of the first element to be considered by the matching logic. From this method's point of view, the "first" element in the stack is actually at
stack(offset)- avail
The number of elements available in the
stackstarting from theoffset.- returns
An option containing the successfully-matched context, or
None.

- def applyChained[B](stack: IndexedSeq[Item], offset: Int, avail: Int, next: ContextMatcher[Item, B]): Option[(A, B)]
The underlying context match method.
The underlying context match method.
Inspects the elements in the XML "tag stack", which is essentially a
List[StartElement], but for performance reasons is represented as an array with an "offset" index and a number of available elements from that offset. If the elements correspond to a context value ofA, the implementation must then pass the remaining elements of the stack to thenextmatcher, i.e. by callingnext(stack, offset + numConsumed, avail - numConsumed).The
nextmatcher is necessary in order to support non-greedy matchers, e.g.ContextMatcher.variableLength, a.k.a.**. Without a reference to thenextmatcher in the chain, matcher implementations would be forced to pick a fixed number of elements for matching, never knowing that the overall match could have succeeded if they had consumed some additional elements.- B

nextmatcher's context type- stack
A reference to the complete XML "tag stack". Note that the responsibility of this method is limited to a *slice* of this value, as defined by
offsetandavail.- offset
The index of the first element to be considered by the matching logic. From this method's point of view, the "first" element in the stack is actually at
stack(offset)- avail
The number of elements available in the
stackstarting from theoffset.- next
The next matcher in the chain.
- returns
If the match succeeded, and the
nextmatch succeded, an Option containing a tuple of both match results. If the match failed, or if thenextmatch failed,None.
