Detailed Description

template<typename Encoding, typename Allocator = MemoryPoolAllocator<>>
class rapidjson::GenericReader< Encoding, Allocator >

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

Encoding	Encoding of both the stream and the parse output.
Allocator	Allocator type for stack.

inline

Constructor.

Parameters

allocator	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)

inline

Constructor.

Parameters

allocator	Optional allocator for allocating stack memory. (Only use for non-destructive parsing)
