Returns:

existing equivalent base or newly created base
getBaseSequence(T
object for the underlying based sequence base
object, @Nullable int[]
one element array for type of tests done to find result NOTE: 0 if map lookup, 10 - set search, 20 - construct and add to map/set with units digit giving max testEquals call type from all tests done

Get an equivalent existing based sequence base or a new one created by passed factory

Note

should only be called by base sequence which are the base for their category: SubSequence implementing managed sequence base

Method Detail

getBaseSequenceback to summary
public <T> @NotNull BasedSequence getBaseSequence(T object, @Nullable int[] callTypes, @NotNull Function<T, BasedSequence> factory)

Get an equivalent existing based sequence base or a new one created by passed factory

Note

should only be called by base sequence which are the base for their category: SubSequence implementing managed sequence base

all others should delegate to these sequences for creating the base

Parameters
<T>
type of base character sequence
object:T

object for the underlying based sequence base

callTypes:@Nullable int[]

one element array for type of tests done to find result NOTE: 0 if map lookup, 10 - set search, 20 - construct and add to map/set with units digit giving max testEquals call type from all tests done

factory:@NotNull Function<T, BasedSequence>

factory to create based sequence from the object

Returns:@NotNull BasedSequence

existing equivalent base or newly created base
