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

class GenericReader

Defined at line 539 of file ../../third_party/rapidjson/include/rapidjson/reader.h

SAX-style JSON parser. Use

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.

Public Methods

void GenericReader<SourceEncoding, TargetEncoding, StackAllocator> (StackAllocator * stackAllocator, size_t stackCapacity)

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)
