Public Methods

Method	Description
Allocate ( int count, bool aligned = false ) : Slice	Allocate an empty space in the buffer There is NO garantees that the allocated slice will be pre-filled with zeroes.
Intern ( Slice data, bool aligned = false ) : Slice	Copy a slice into the buffer, with optional alignement, and return a new identical slice.
InternRange ( FdbKeyRange range ) : FdbKeyRange	Copy a pair of keys into the buffer, and return a new identical pair
InternRange ( Slice begin, Slice end ) : FdbKeyRange	Copy a pair of keys into the buffer, and return a new identical pair
InternRangeFromKey ( Slice key ) : FdbKeyRange	Copy a key into the buffer, and return a new range containing only that key
InternSelector ( FdbKeySelector selector ) : FdbKeySelector	Copy a key selector into the buffer, and return a new identical selector
InternSelectorPair ( FdbKeySelectorPair pair ) : FdbKeySelectorPair	Copy a pair of key selectors into the buffer, and return a new identical pair
Reset ( ) : void	Reset the buffer to its initial state None of the existing buffers are kept, but the new page will keep the current page size (that may be larger than the initial size). Any previously allocated slice from this buffer will be untouched.
ResetUnsafe ( ) : void	Reset the buffer to its initial state, and reuse the current page. This recycle the current page. The caller should ensure that nobody has a reference to a previously generated slice.
SliceBuffer ( ) : JetBrains.Annotations	Create a new slice buffer with the default page size
SliceBuffer ( int pageSize ) : JetBrains.Annotations	Ceate a new slice buffer with the specified page size

Private Methods

Method	Description
AllocateFallback ( int count ) : Slice
GetPages ( ) : Slice[]
Intern ( Slice data, Slice suffix, bool aligned = false ) : Slice	Copy a slice into the buffer, immediately followed by a suffix, and return a new slice that is the concatenation of the two. When data is empty, suffix is returned without being copied to the buffer itself.
Keep ( Slice chunk ) : void	Adds a buffer to the list of allocated slices
Reset ( bool keep ) : void

Method Details

Allocate() public method

Allocate an empty space in the buffer

There is NO garantees that the allocated slice will be pre-filled with zeroes.

public Allocate ( int count, bool aligned = false ) : Slice
count	int	Number of bytes to allocate
aligned	bool	If true, align the start of the slice with the default padding size.
return	Slice

Intern() public method

Copy a slice into the buffer, with optional alignement, and return a new identical slice.

public Intern ( Slice data, bool aligned = false ) : Slice
data	Slice	Data to copy in the buffer
aligned	bool	If true, align the index of first byte of the slice with a multiple of 8 bytes
return	Slice

InternRange() public method

Copy a pair of keys into the buffer, and return a new identical pair

public InternRange ( FdbKeyRange range ) : FdbKeyRange
range	FdbKeyRange	Key range
return	FdbKeyRange

InternRange() public method

Copy a pair of keys into the buffer, and return a new identical pair

public InternRange ( Slice begin, Slice end ) : FdbKeyRange
begin	Slice	Begin key of the range
end	Slice	End key of the range
return	FdbKeyRange

InternRangeFromKey() public method

Copy a key into the buffer, and return a new range containing only that key

public InternRangeFromKey ( Slice key ) : FdbKeyRange
key	Slice	Key to copy to the buffer
return	FdbKeyRange

InternSelector() public method

Copy a key selector into the buffer, and return a new identical selector

public InternSelector ( FdbKeySelector selector ) : FdbKeySelector
selector	FdbKeySelector	Key selector to copy to the buffer
return	FdbKeySelector

InternSelectorPair() public method

Copy a pair of key selectors into the buffer, and return a new identical pair

public InternSelectorPair ( FdbKeySelectorPair pair ) : FdbKeySelectorPair
pair	FdbKeySelectorPair	Pair of key selectors to copy to the buffer
return	FdbKeySelectorPair

Reset() public method

Reset the buffer to its initial state

None of the existing buffers are kept, but the new page will keep the current page size (that may be larger than the initial size). Any previously allocated slice from this buffer will be untouched.

public Reset ( ) : void
return	void

ResetUnsafe() public method

Reset the buffer to its initial state, and reuse the current page.

This recycle the current page. The caller should ensure that nobody has a reference to a previously generated slice.

public ResetUnsafe ( ) : void
return	void

SliceBuffer() public method

Create a new slice buffer with the default page size

public SliceBuffer ( ) : JetBrains.Annotations
return	JetBrains.Annotations

SliceBuffer() public method

Ceate a new slice buffer with the specified page size

public SliceBuffer ( int pageSize ) : JetBrains.Annotations
pageSize	int	Initial page size
return	JetBrains.Annotations
