      • hasMemoryLevel

        boolean hasMemoryLevel()
         Value from 1 to 9 that controls the amount of internal memory used by zlib. Higher values
 use more memory, but are faster and produce better compression results. The default value is 5.
        .google.protobuf.UInt32Value memory_level = 1 [(.validate.rules) = { ... }
        Returns:
        Whether the memoryLevel field is set.

      • getMemoryLevel

        com.google.protobuf.UInt32Value getMemoryLevel()
         Value from 1 to 9 that controls the amount of internal memory used by zlib. Higher values
 use more memory, but are faster and produce better compression results. The default value is 5.
        .google.protobuf.UInt32Value memory_level = 1 [(.validate.rules) = { ... }
        Returns:
        The memoryLevel.

      • getMemoryLevelOrBuilder

        com.google.protobuf.UInt32ValueOrBuilder getMemoryLevelOrBuilder()
         Value from 1 to 9 that controls the amount of internal memory used by zlib. Higher values
 use more memory, but are faster and produce better compression results. The default value is 5.
        .google.protobuf.UInt32Value memory_level = 1 [(.validate.rules) = { ... }

      • getCompressionLevelValue

        int getCompressionLevelValue()
         A value used for selecting the zlib compression level. This setting will affect speed and
 amount of compression applied to the content. "BEST" provides higher compression at the cost of
 higher latency, "SPEED" provides lower compression with minimum impact on response time.
 "DEFAULT" provides an optimal result between speed and compression. This field will be set to
 "DEFAULT" if not specified.
        .envoy.extensions.filters.http.gzip.v3.Gzip.CompressionLevel.Enum compression_level = 3 [(.validate.rules) = { ... }
        Returns:
        The enum numeric value on the wire for compressionLevel.

      • getCompressionLevel

        Gzip.CompressionLevel.Enum getCompressionLevel()
         A value used for selecting the zlib compression level. This setting will affect speed and
 amount of compression applied to the content. "BEST" provides higher compression at the cost of
 higher latency, "SPEED" provides lower compression with minimum impact on response time.

        Returns:
        The compressionLevel.

      • getCompressionStrategyValue

        int getCompressionStrategyValue()
         A value used for selecting the zlib compression strategy which is directly related to the
 characteristics of the content. Most of the time "DEFAULT" will be the best choice, though
 there are situations which changing this parameter might produce better results. For example,
 run-length encoding (RLE) is typically used when the content is known for having sequences
 which same data occurs many consecutive times. For more information about each strategy, please
 refer to zlib manual.
        .envoy.extensions.filters.http.gzip.v3.Gzip.CompressionStrategy compression_strategy = 4 [(.validate.rules) = { ... }
        Returns:
        The enum numeric value on the wire for compressionStrategy.

      • hasWindowBits

        boolean hasWindowBits()
         Value from 9 to 15 that represents the base two logarithmic of the compressor's window size.
 Larger window results in better compression at the expense of memory usage. The default is 12
 which will produce a 4096 bytes window. For more details about this parameter, please refer to
 zlib manual > deflateInit2.
        .google.protobuf.UInt32Value window_bits = 9 [(.validate.rules) = { ... }
        Returns:
        Whether the windowBits field is set.
