Detailed Description
template<typename SourceEncoding, typename TargetEncoding, typename StackAllocator = CrtAllocator>
class GenericReader< SourceEncoding, TargetEncoding, StackAllocator >
SAX-style JSON parser. Use Reader for UTF8 encoding and default allocator.
GenericReader parses JSON text from a stream, and send events synchronously to an object implementing Handler concept.
It needs to allocate a stack for storing a single decoded string during non-destructive parsing.
For in-situ parsing, the decoded string is directly written to the source text string, no temporary buffer is required.
A GenericReader object can be reused for parsing multiple JSON text.
- Template Parameters:
-
SourceEncoding Encoding of the input stream. TargetEncoding Encoding of the parse output. StackAllocator Allocator type for stack.
