Detailed Description

Binary reader.

This class is implemented as a reference to an implementation so copying of this class instance will only create another reference to the same underlying object.

Note: User should not store copy of this instance as it can be invalidated as soon as the initially passed to user instance has been destructed. For example this means that if user received an instance of this class as a function argument then he should not store and use copy of this class out of the scope of this function.

Constructor & Destructor Documentation

◆ BinaryReader()

ignite::binary::BinaryReader::BinaryReader ( ignite::impl::binary::BinaryReaderImpl * impl )

Constructor.

Internal method. Should not be used by user.

Parameters

impl	Implementation.

Member Function Documentation

◆ RawReader()

BinaryRawReader ignite::binary::BinaryReader::RawReader ( )

Get raw reader for this reader.

Returns: Raw reader.

◆ ReadArray()

template<typename T >

BinaryArrayReader<T> ignite::binary::BinaryReader::ReadArray ( const char * fieldName )

inline

Start array read.

Every time you get a BinaryArrayReader from BinaryReader you start reading session. Only one single reading session can be open at a time. So it is not allowed to start new reading session until all elements of the collection have been read.

Parameters

fieldName Field name.

Returns: Array reader.

◆ ReadBinaryEnum()

BinaryEnumEntry ignite::binary::BinaryReader::ReadBinaryEnum ( const char * fieldName )

Read enum entry.

Parameters

fieldName Field name.

Returns: Enum entry.
