public static enum JsonParser.Feature
Enumeration that defines all on/off features for parsers.
Enum Constant Summary | |
---|---|
ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER
Feature that can be enabled to accept quoting of all character using backslash qooting mechanism: if not enabled, only characters that are explicitly listed by JSON specification can be thus escaped (see JSON spec for small list of these characters) |
|
ALLOW_COMMENTS
Feature that determines whether parser will allow use of Java/C++ style comments (both '/'+'*' and '//' varieties) within parsed content or not. |
|
ALLOW_NON_NUMERIC_NUMBERS
Feature that allows parser to recognize set of "Not-a-Number" (NaN) tokens as legal floating number values (similar to how many other data formats and programming language source code allows it). |
|
ALLOW_NUMERIC_LEADING_ZEROS
Feature that determines whether parser will allow JSON integral numbers to start with additional (ignorable) zeroes (like: 000001). |
|
ALLOW_SINGLE_QUOTES
Feature that determines whether parser will allow use of single quotes (apostrophe, character '\'') for quoting Strings (names and String values). |
|
ALLOW_UNQUOTED_CONTROL_CHARS
Feature that determines whether parser will allow JSON Strings to contain unquoted control characters (ASCII characters with value less than 32, including tab and line feed characters) or not. |
|
ALLOW_UNQUOTED_FIELD_NAMES
Feature that determines whether parser will allow use of unquoted field names (which is allowed by Javascript, but not by JSON specification). |
|
AUTO_CLOSE_SOURCE
Feature that determines whether parser will automatically close underlying input source that is NOT owned by the parser. |

public static final JsonParser.Feature AUTO_CLOSE_SOURCE
InputStream
and Reader
instances used to create the parser. If enabled, parser
will handle closing, as long as parser itself gets closed:
this happens when end-of-input is encountered, or parser
is closed by a call to JsonParser.close()
.
Feature is enabled by default.
public static final JsonParser.Feature ALLOW_COMMENTS
Since JSON specification does not mention comments as legal construct, this is a non-standard feature; however, in the wild this is extensively used. As such, feature is disabled by default for parsers and must be explicitly enabled.
public static final JsonParser.Feature ALLOW_UNQUOTED_FIELD_NAMES
Since JSON specification requires use of double quotes for field names, this is a non-standard feature, and as such disabled by default.
public static final JsonParser.Feature ALLOW_SINGLE_QUOTES
Since JSON specification requires use of double quotes for field names, this is a non-standard feature, and as such disabled by default.
public static final JsonParser.Feature ALLOW_UNQUOTED_CONTROL_CHARS
Since JSON specification requires quoting for all control characters, this is a non-standard feature, and as such disabled by default.
public static final JsonParser.Feature ALLOW_BACKSLASH_ESCAPING_ANY_CHARACTER
Since JSON specification requires quoting for all control characters, this is a non-standard feature, and as such disabled by default.
public static final JsonParser.Feature ALLOW_NUMERIC_LEADING_ZEROS
JsonParser.getText()
).
Since JSON specification does not allow leading zeroes, this is a non-standard feature, and as such disabled by default.
public static final JsonParser.Feature ALLOW_NON_NUMERIC_NUMBERS
Since JSON specification does not allow use of such values, this is a non-standard feature, and as such disabled by default.
