Member Function Documentation

build()

void Arcane::LZ4DeflateService::build ( void )

inlineoverridevirtual

Build-level construction of the service.

This method is called right after the constructor.

Reimplemented from Arcane::AbstractService.

Definition at line 50 of file LZ4DeflateService.cc.

compress()

void Arcane::LZ4DeflateService::compress ( ByteConstArrayView values, ByteArray & compressed_values )

inlineoverridevirtual

Compresses the data values and stores it in compressed_values.

This operation may throw an IOException exception in case of an error.

Implements Arcane::IDeflateService.

Definition at line 52 of file LZ4DeflateService.cc.

References Arcane::Array< T >::data(), Arcane::ConstArrayView< T >::data(), Arcane::TraceAccessor::info(), Arcane::Array< T >::resize(), and Arcane::ConstArrayView< T >::size().

Here is the call graph for this function:

decompress()

void Arcane::LZ4DeflateService::decompress ( ByteConstArrayView compressed_values, ByteArrayView values )

inlineoverridevirtual

Decompresses the data compressed_values and stores it in values.

values must already have been allocated to the necessary size to contain the decompressed data. This operation may throw an IOException exception in case of an error.

Implements Arcane::IDeflateService.

Definition at line 85 of file LZ4DeflateService.cc.
