Factory to create compression codec.

Field Summary

Fields

Modifier and Type	Field	Description
static final CompressionCodec.Factory	INSTANCE	This combines all the available factories registered as service providers in the module path.

Method Summary

Modifier and Type	Method	Description
CompressionCodec	createCodec(CompressionUtil.CodecType codecType)	Creates the codec based on the codec type.
CompressionCodec	createCodec(CompressionUtil.CodecType codecType, int compressionLevel)	Creates the codec based on the codec type and compression level.

Field Details

INSTANCE

static final CompressionCodec.Factory INSTANCE

This combines all the available factories registered as service providers in the module path. For each compression codec type, it will use whatever factory supports it, i.e. doesn't throw on `createCodec(type)`. If multiple factories registered as service providers support the same codec type, the first one encountered while iterating over the ServiceLoader will be selected. A codec type that is not supported by any registered service provider will fall back to NoCompressionCodec.Factory.INSTANCE for backwards compatibility.

Method Details

createCodec

CompressionCodec createCodec(CompressionUtil.CodecType codecType)

Creates the codec based on the codec type.

createCodec

CompressionCodec createCodec(CompressionUtil.CodecType codecType,
 int compressionLevel)

Creates the codec based on the codec type and compression level.
