equal to windowSize - 1 . |
Parameters.Builder |
Parameters.Builder.tunedForCompressionRatio()
Changes the default setting for "nice back-reference length" and "maximum number of candidates" for improved
compression ratio at the cost of compression speed.
|
Parameters.Builder |
Parameters.Builder.tunedForSpeed()
Changes the default setting for "nice back-reference length" and "maximum number of candidates" for improved
compression speed at the cost of compression ratio.
