public class JsonParserSequence extends JsonParserDelegate
JsonParsers to create a single logical sequence of
tokens, as a single JsonParser.
Fairly simple use of JsonParserDelegate: only need
to override nextToken() to handle transition
JsonParser.Feature, JsonParser.NumberType| Modifier and Type | Field and Description |
|---|---|
protected boolean |
_checkForExistingToken
Configuration that determines whether state of parsers is first verified
to see if parser already points to a token (that is,
JsonParser.hasCurrentToken() returns true), and if so
that token is first return before JsonParser.nextToken() is called. |
protected boolean |
_hasToken
Flag used to indicate that `JsonParser.nextToken()` should not be called,
due to parser already pointing to a token.
|
protected int |
_nextParserIndex
Index of the next parser in
_parsers. |
protected JsonParser[] |
_parsers
Parsers other than the first one (which is initially assigned
as delegate)

| Modifier and Type | Method and Description |
|---|---|
protected void |
addFlattenedActiveParsers(List<JsonParser> listToAddIn) |
void |
close()
Closes the parser so that no further iteration or data access
can be made; will also close the underlying input source
if parser either owns the input source, or feature
JsonParser.Feature.AUTO_CLOSE_SOURCE is enabled. |
int |
containedParsersCount()
Method that is most useful for debugging or testing;
returns actual number of underlying parsers sequence
was constructed with (nor just ones remaining active)
|
static JsonParserSequence |
createFlattened(boolean checkForExistingToken,
JsonParser first,
JsonParser second)
Method that will construct a parser (possibly a sequence) that
contains all given sub-parsers.
|
static JsonParserSequence |
createFlattened(JsonParser first,
JsonParser second)
Deprecated.
Since 2.8 use
createFlattened(boolean, JsonParser, JsonParser)
instead |
JsonToken |
nextToken()
Main iteration method, which will advance stream enough
to determine type of the next token, if any.
|
JsonParser |
skipChildren()
Need to override, re-implement similar to how method defined in
ParserMinimalBase, to keep
state correct here. |
protected JsonToken |
switchAndReturnNext() |
protected boolean |
switchToNext()
Method that will switch active delegate parser from the current one
to the next parser in sequence, if there is another parser left:
if so, the next parser will become the active delegate parser.

protected final boolean _checkForExistingToken
JsonParser.hasCurrentToken() returns true), and if so
that token is first return before JsonParser.nextToken() is called.
If enabled, this check is made; if disabled, no check is made and
JsonParser.nextToken() is always called for all parsers.
Default setting is false (for backwards-compatibility)
so that possible existing token is not considered for parsers.

JsonParserJsonParser.Feature.AUTO_CLOSE_SOURCE is enabled.
Whether parser owns the input source depends on factory
method that was used to construct instance (so check
JsonFactory for details,
but the general
idea is that if caller passes in closable resource (such
as InputStream or Reader) parser does NOT
own the source; but if it passes a reference (such as
File or URL and creates
stream or reader it does own them.close in interface Closeableclose in interface AutoCloseableclose in class JsonParserDelegateIOExceptionpublic JsonToken nextToken() throws IOException
