data class RegionSecurityPolicyUserDefinedFieldArgs(val base: Output<String>, val mask: Output<String>? = null, val name: Output<String>? = null, val offset: Output<Int>? = null, val size: Output<Int>? = null) : ConvertibleToJava<RegionSecurityPolicyUserDefinedFieldArgs>
If specified, apply this mask (bitwise AND) to the field to ignore bits before matching. Encoded as a hexadecimal number (starting with "0x"). The last byte of the field (in network byte order) corresponds to the least significant byte of the mask.
