Detailed Description

Abstract binary stream for serialization.

Subclasses implement the raw Read/Write byte methods. The template Write/Read methods delegate to Serializer for endian-aware, type-safe binary I/O.

Note

Subclasses that override Read(void*, size_t) or Write(const void*, size_t) must add using Stream::Read; and using Stream::Write; to make the template overloads visible (C++ name-hiding rule).

Member Function Documentation

Read() [1/2]

template<typename T >

bool tvm::support::Stream::Read ( T *  out_data )

inline

Read a typed value using Serializer<T>.

Template Parameters

T	The data type (must have a Serializer<T> specialization).

Parameters

out_data

Pointer to receive the value.

Returns

true on success.

Read() [2/2]

virtual size_t tvm::support::Stream::Read ( void *  ptr, size_t  size  )

pure virtual

Read raw bytes from the stream.

Parameters

ptr	Destination buffer.
size	Number of bytes to read.

Returns

Number of bytes actually read.

ReadArray()

template<typename T >

bool tvm::support::Stream::ReadArray ( T *  data, size_t  num_elems  )

inline

Read an array of typed values element by element.

Parameters

data	Pointer to the first element.
num_elems	Number of elements.

Returns

true on success.

Write() [1/2]

template<typename T >

void tvm::support::Stream::Write ( const T &  data )

inline

Write a typed value using Serializer<T>.

Template Parameters

T	The data type (must have a Serializer<T> specialization).

Parameters

data	The value to write.

Write() [2/2]

virtual size_t tvm::support::Stream::Write ( const void *  ptr, size_t  size  )

pure virtual

Write raw bytes to the stream.

Parameters

ptr	Source buffer.
size	Number of bytes to write.

Returns

Number of bytes actually written.

WriteArray()

template<typename T >

void tvm::support::Stream::WriteArray ( const T *  data, size_t  num_elems  )

inline

Write an array of typed values element by element.

Parameters

data	Pointer to the first element.
num_elems	Number of elements.
