VersionDecorator

Alternative contiguous version decorator implementation for usage in less performance critical applications. Is capable of converting through multiple struct versions in one go for added convenience.

Amount of allowed conversions for single call is set via constructor argument, 10 by default

class VersionDecorator {

alias This = VersionDecorator;

protected

VersionHandlingException e;

this(size_t limit, size_t buffer_size);

static void[] store(S input, Buffer!(void) buffer);

static void[] store(S input, D[] buffer);

Contiguous!(S) load(Buffer!(void) buffer);

Contiguous!(S) load(void[] buffer);

Contiguous!(S) loadCopy(void[] buffer, Contiguous!(S) copy_buffer);

Contiguous!(S) handleVersion(Buffer!(void) buffer, Version.Type input_version);

Contiguous!(S) handleVersion(void[] buffer, Version.Type input_version);

Contiguous!(S) convert(Buffer!(void) buffer);

Contiguous!(S) convert(void[] buffer);

}

Functions

convert Contiguous!(S) convert(Buffer!(void) buffer)
Contiguous!(S) convert(void[] buffer): Helper method that takes care of actual conversion routine between two struct types (those are assumed to be of compatible versions)
handleVersion Contiguous!(S) handleVersion(Buffer!(void) buffer, Version.Type input_version)
Contiguous!(S) handleVersion(void[] buffer, Version.Type input_version): Utility method to convert struct contained in input buffer to needed struct version. Converted struct will be stored in the same buffer replacing old data.
load Contiguous!(S) load(Buffer!(void) buffer)
Contiguous!(S) load(void[] buffer): Loads versioned struct from buffer in-place
loadCopy Contiguous!(S) loadCopy(void[] buffer, Contiguous!(S) copy_buffer): Loads versioned struct from buffer and stores resulting data in copy_buffer, leaving buffer untouched.

Static functions

store void[] store(S input, Buffer!(void) buffer)
void[] store(S input, D[] buffer): Serializes input with This.Serializer and prepends version number before struct data in the buffer.
