Detailed Description

template<typename SourceEncoding, typename TargetEncoding, typename StackAllocator = CrtAllocator>
class rapidjson::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.

Constructor & Destructor Documentation

template<typename SourceEncoding, typename TargetEncoding, typename StackAllocator = CrtAllocator>

rapidjson::GenericReader< SourceEncoding, TargetEncoding, StackAllocator >::GenericReader ( StackAllocator *  stackAllocator = 0, size_t  stackCapacity = kDefaultStackCapacity  )

inline

Constructor.

Parameters

stackAllocator	Optional allocator for allocating stack memory. (Only use for non-destructive parsing)
stackCapacity	stack capacity in bytes for storing a single decoded string. (Only use for non-destructive parsing)
