ArrayBlock

Add contents of another block to this block.

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 x of type Any, x.equals(x) should return true.
• It is symmetric: for any instances x and y of type Any, x.equals(y) should return true if and only if y.equals(x) returns true.
• It is transitive: for any instances x, y, and z of type Any if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.

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)).

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

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.

Select the maximum value of this block or b.

Merge the data in block b with the data in this block. The merge will happen in-place and the data for this block will be changed. The policy is:

• A value is preferred over NaN

• If both blocks have values the larger value is selected. This is somewhat arbitrary, but generally works for us as most data is positive and missing data due to failures somewhere lead to a smaller number.

Select the minimum value of this block or b.

Reset this block so it can be re-used.

Returns a copy of the block as a simple array-backed block.

Returns a string representation of the object.

The default representation is platform dependent.

Update the value for the specified position.

Return the value for a given position in the block. All implementations should make this a constant time operation. The default implementation assumes a single value.

Used to get a quick estimate of the size of numeric primatives and arrays of numeric primitives.

Number of bytes required to store this block in a simple binary representation.
