Mutable block type that tries to compress data as it is updated. The main compression benefit comes by not needed to store the most common values that are seen in the data. Initially 2 bits per value will be used that indicate one of four common values: NaN, 0, 1, 1/60. If another value is used, then it will update the buffer to use 4 bits per value that can be one of the four common values or an index to an explicit value. If more than 12 distinct values are seen, then it will update the buffer to just be an array of double values.

Compares the receiver object (this) with the argument object (that) for equivalence.
Compares the receiver object (this) with the argument object (that) for equivalence.
Any implementation of this method should be an equivalence relation:
- It is reflexive: for any instance
xof typeAny,x.equals(x)should returntrue. - It is symmetric: for any instances
xandyof typeAny,x.equals(y)should returntrueif and only ify.equals(x)returnstrue. - It is transitive: for any instances
x,y, andzof typeAnyifx.equals(y)returnstrueandy.equals(z)returnstrue, thenx.equals(z)should returntrue.
If you override this method, you should verify that your implementation remains an equivalence relation. Additionally, when overriding this method it is usually necessary to override hashCode to ensure that objects which are "equal" (o1.equals(o2) returns true) hash to the same scala.Int. (o1.hashCode.equals(o2.hashCode)).
Value parameters
- that
-
the object to compare against this object for equality.

Return the value for a given position in the block. All implementations should make this a constant time operation.
Return the value for a given position in the block. All implementations should make this a constant time operation.
Value parameters

Calculates a hash code value for the object.
Calculates a hash code value for the object.
The default hashing algorithm is platform dependent.
Note that it is allowed for two objects to have identical hash codes (o1.hashCode.equals(o2.hashCode)) yet not be equal (o1.equals(o2) returns false). A degenerate implementation could always return 0. However, it is required that if two objects are equal (o1.equals(o2) returns true) that they have identical hash codes (o1.hashCode.equals(o2.hashCode)). Therefore, when overriding this method, be sure to verify that the behavior is consistent with the equals method.
