详细描述

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.

模板参数

SourceEncoding	Encoding of the input stream.
TargetEncoding	Encoding of the parse output.
StackAllocator	Allocator type for stack.

构造及析构函数说明

GenericReader()

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

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

inline

Constructor.

参数

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)

成员函数说明

IterativeParseComplete()

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

RAPIDJSON_FORCEINLINE bool rapidjson::GenericReader< SourceEncoding, TargetEncoding, StackAllocator >::IterativeParseComplete ( ) const

inline

返回

Whether the JSON has been fully decoded.

IterativeParseNext()

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

template<unsigned parseFlags, typename InputStream , typename Handler >

bool rapidjson::GenericReader< SourceEncoding, TargetEncoding, StackAllocator >::IterativeParseNext ( InputStream &  is, Handler &  handler  )

inline

Parse() [2/2]

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

template<typename InputStream , typename Handler >

ParseResult rapidjson::GenericReader< SourceEncoding, TargetEncoding, StackAllocator >::Parse ( InputStream &  is, Handler &  handler  )

inline
