Description

JsonTokenizer [constructor]

Constructors

~JsonTokenizer [destructor]

Destroy this object.

advanceToNextToken

Move to the next token in the source object. Return 0 on success and a non‐zero value otherwise. The return value is non‐zero when there are no more tokens in the source object. The behavior is undefined unless a source object was specified on construction and/or a call to reset.

get_allocator

Return the allocator used by this object to supply memory. Note that if no allocator was supplied at construction the default allocator in effect at construction is used.

reset

Reset this tokenizer to use the specified json as a source object for tokens. All state associated with a previously specified source object (if any) is discarded. The behavior is undefined unless json‐>isArray() or json‐>isObject().

tokenType

Return the type of the current token.

Description

print

Write the string representation of the specified enumeration value to the specified output stream, and return a reference to stream. Optionally specify an initial indentation level, whose absolute value is incremented recursively for nested objects. If level is specified, optionally specify spacesPerLevel, whose absolute value indicates the number of spaces per indentation level for this and all of its nested objects. If level is negative, suppress indentation of the first line. If spacesPerLevel is negative, format the entire output on one line, suppressing all but the initial indentation (as governed by level). See toAscii for what constitutes the string representation of a JsonTokenizer::TokenType value.

toAscii

Return the non‐modifiable string representation corresponding to the specified enumeration value, if it exists, and a unique (error) string otherwise. The string representation of value matches its corresponding enumerator name with the "e_" prefix elided. For example: ` bsl::cout << DstPolicy::toAscii(JsonTokenizer::e_ELEMENT_VALUE); ` will print the following on standard output: ` ELEMENT_VALUE ` Note that specifying a value that does not match any of the enumerators will result in a string representation that is distinct from any of those corresponding to the enumerators, but is otherwise unspecified.

Description

BloombergLP::baljsn::JsonTokenizer_Visitor

This class provides a mechanism for extracting token information from a bdljsn::Json object, transferring that information to a parent baljsn::JsonTokenizer object (which considers this visitor a friend), and, if appropriate, arranging for the visiting of a subordinate bdljsn::Json object.
