Predicate
SingleElementContextMatcher that successfully matches (with no result) if the
given predicate function returns true
for the matched element.

Create a new matcher by forming a chain with this matcher at the front, and the next
matcher at the back.
In other words, a matcher for a context within another context.
Create a new matcher by forming a chain with this matcher at the front, and the next
matcher at the back.
In other words, a matcher for a context within another context.
- Type parameters:
- A1
To satisfy covariance on A
- B
The
next
matcher's context type- R
The "reduced" content type, derived from the tuple type
(A, B)
based on thereduce
rule.
- Value parameters:
- next
A matcher which will be used to match the "inner" context
- reduce
The
TypeReduce
rule to help omitUnit
from the resulting context type
- Returns:
A matcher which delegates to
this
matcher first, then thenext
matcher for the remaining stack.- Inherited from:
- ContextMatcher
Creates a new single-element matcher which combines the results of both this
matcher and that
matcher.
Both this
and that
will operate on the first element of the stack (as opposed to Chained matchers).

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 of A
, the implementation
must then pass the remaining elements of the stack to the next
matcher, i.e. by calling
next(stack, offset + numConsumed, avail - numConsumed)
.
The difference between this method and applyChained
is the lack of the next
parameter; in this
method, the current matcher is assumed to be the end of the chain.
- Value parameters:
- avail
The number of elements available in the
stack
starting from theoffset
.- 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)
- 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
offset
andavail
.
- Returns:
An option containing the successfully-matched context, or
None

Create a new ContextMatcher which will fall back to a second matcher in the event that this matcher fails to match a context.
Create a new ContextMatcher which will fall back to a second matcher in the event that this matcher fails to match a context.
- Type parameters:
- A2
The resulting context type (common supertype between this matcher and
that
)
- Value parameters:
- that
The matcher which will be used as the fallback
- Returns:
A matcher that falls back to another matcher in case of failure
