doubleValToString

static String doubleValToString(Object val)

primitiveDoubleValToString

static String primitiveDoubleValToString(double val)

toString

static String toString(@NotNull
 DbDoubleArray array,
 long maxElements)

Helper method for implementing Object.toString().

Parameters:

array - The DbDoubleArray to convert to a String

Returns:

The String representation of array

toString

static String toString(@NotNull
 DbDoubleArray array)

Helper method for implementing Object.equals(Object).

Parameters:

aArray - The LHS of the equality test (always a DbDoubleArray)

b - The RHS of the equality test

Returns:

Whether the two inputs are equal

hashCode

static int hashCode(@NotNull
 DbDoubleArray array)

Helper method for implementing Object.hashCode(). Follows the pattern in Arrays.hashCode(Object[]).

Parameters:

array - The DbDoubleArray to hash

Returns:

The hash code
