Detailed Description

A wrapper around grpc_slice.

A slice represents a contiguous reference counted array of bytes. It is cheap to take references to a slice, and it is cheap to create a slice pointing to a subset of another slice.

Constructor & Destructor Documentation

Slice() [1/11]

grpc::Slice::Slice ( )

inline

Construct an empty slice.

~Slice()

grpc::Slice::~Slice ( )

inline

Destructor - drops one reference.

Slice() [2/11]

grpc::Slice::Slice ( grpc_slice  slice, AddRef    )

inline

Construct a slice from slice, adding a reference.

Slice() [3/11]

grpc::Slice::Slice ( grpc_slice  slice, StealRef    )

inline

Construct a slice from slice, stealing a reference.

Slice() [4/11]

grpc::Slice::Slice ( size_t  len )

inline

Allocate a slice of specified size.

Slice() [5/11]

grpc::Slice::Slice ( const void *  buf, size_t  len  )

inline

Construct a slice from a copied buffer.

Slice() [6/11]

grpc::Slice::Slice ( const grpc::string &  str )

inline

Construct a slice from a copied string.

Slice() [7/11]

grpc::Slice::Slice ( const void *  buf, size_t  len, StaticSlice    )

inline

Construct a slice from a static buffer.

Slice() [8/11]

grpc::Slice::Slice ( const Slice &  other )

inline

Copy constructor, adds a reference.

Slice() [9/11]

grpc::Slice::Slice ( void *  buf, size_t  len, void(*)(void *)  destroy, void *  user_data  )

inline

Create a slice pointing at some data.

Calls malloc to allocate a refcount for the object, and arranges that destroy will be called with the user data pointer passed in at destruction. Can be the same as buf or different (e.g., if data is part of a larger structure that must be destroyed when the data is no longer needed)

Slice() [10/11]

grpc::Slice::Slice ( void *  buf, size_t  len, void(*)(void *)  destroy  )

inline

Specialization of above for common case where buf == user_data.

Slice() [11/11]

grpc::Slice::Slice ( void *  buf, size_t  len, void(*)(void *, size_t)  destroy  )

inline

Similar to the above but has a destroy that also takes slice length.

Member Function Documentation

begin()

const uint8_t* grpc::Slice::begin ( ) const

inline

Raw pointer to the beginning (first element) of the slice.

c_slice()

grpc_slice grpc::Slice::c_slice ( ) const

inline

Raw C slice. Caller needs to call grpc_slice_unref when done.

end()

const uint8_t* grpc::Slice::end ( ) const

inline

Raw pointer to the end (one byte past the last element) of the slice.

operator=()

Slice& grpc::Slice::operator= ( Slice  other )

inline

Assignment, reference count is unchanged.

size()

size_t grpc::Slice::size ( ) const

inline

Byte size.
