public class FilteringGeneratorDelegate extends JsonGeneratorDelegate
JsonGeneratorDelegate that allows use of
TokenFilter for outputting a subset of content that
caller tries to generate.JsonGenerator.Feature| Modifier and Type | Field and Description |
|---|---|
protected boolean |
_allowMultipleMatches
Flag that determines whether filtering will continue after the first
match is indicated or not: if `false`, output is based on just the first
full match (returning
TokenFilter.INCLUDE_ALL) and no more
checks are made; if `true` then filtering will be applied as necessary
until end of content. |
protected TokenFilterContext |
_filterContext
Although delegate has its own output context it is not sufficient since we actually
have to keep track of excluded (filtered out) structures as well as ones delegate
actually outputs.
|
protected TokenFilter.Inclusion |
_inclusion
Flag that determines whether path leading up to included content should
also be automatically included or not.
|
protected TokenFilter |
_itemFilter
State that applies to the item within container, used where applicable.
|
protected int |
_matchCount
Number of tokens for which
TokenFilter.INCLUDE_ALL
has been returned |
protected TokenFilter |
rootFilter
Object consulted to determine whether to write parts of content generator
is asked to write or not.

int offset,
int len) |

Default implementation just calls JsonGenerator.writeString(String);
sub-classes should override it with more efficient implementation
if possible.

JsonGeneratorlen is < 0, then write all contents of the reader.
Otherwise, write only len characters.
Note: actual length of content available may exceed len but
can not be less than it: if not enough content available, a
JsonGenerationException will be thrown.

JsonGeneratorJsonGenerator.writeString(String) but that takes as
its input a UTF-8 encoded String that is to be output as-is, without additional
escaping (type of which depends on data format; backslashes for JSON).
However, quoting that data format requires (like double-quotes for JSON) will be added
around the value if and as necessary.
Note that some backends may choose not to support this method: for
example, if underlying destination is a Writer
using this method would require UTF-8 decoding.
If so, implementation may instead choose to throw a
UnsupportedOperationException due to ineffectiveness
of having to decode input.

JsonGeneratorJsonGenerator.writeString(String) but that takes as its input
a UTF-8 encoded String which has not been escaped using whatever
escaping scheme data format requires (for JSON that is backslash-escaping
for control characters and double-quotes; for other formats something else).
This means that textual JSON backends need to check if value needs
JSON escaping, but otherwise can just be copied as is to output.
Also, quoting that data format requires (like double-quotes for JSON) will be added
around the value if and as necessary.
Note that some backends may choose not to support this method: for
example, if underlying destination is a Writer
using this method would require UTF-8 decoding.
In this case
generator implementation may instead choose to throw a
UnsupportedOperationException due to ineffectiveness
of having to decode input.

The default implementation delegates to JsonGenerator.writeRaw(String);
other backends that support raw inclusion of text are encouraged
to implement it in more efficient manner (especially if they
use UTF-8 encoding).

Note: because JSON Strings can not contain unescaped linefeeds,
if linefeeds are included (as per last argument), they must be
escaped. This adds overhead for decoding without improving
readability.
Alternatively if linefeeds are not included,
resulting String value may violate the requirement of base64
RFC which mandates line-length of 76 characters and use of
linefeeds. However, all JsonParser implementations
are required to accept such "long line base64"; as do
typical production-level base64 decoders.

JsonGeneratorJsonGenerator.writeString(java.lang.String) method can not be used; nor
JsonGenerator.writeRaw(java.lang.String) because that does not properly handle
value separators needed in Array or Object contexts.
Note: because of lack of type safety, some generator
implementations may not be able to implement this
method. For example, if a binary JSON format is used,
it may require type information for encoding; similarly
for generator-wrappers around Java objects or JSON nodes.
If implementation does not implement this method,
it needs to throw UnsupportedOperationException.
