Description copied from class: InstantPatternDynamicFormatter.PatternSequence

Tries to merge two pattern sequences.

If not {@link null}, the pattern sequence returned by this method must:

1. Have a InstantPatternDynamicFormatter.PatternSequence.precision, which is the minimum of the precisions of the two merged sequences.
2. Create formatters that are equivalent to the concatenation of the formatters produced by the two merged sequences.

The returned pattern sequence should try to achieve these two goals:

1. Create formatters which are faster than the concatenation of the formatters produced by the two merged sequences.
2. It should be {@link null} if one of the pattern sequences is effectively constant over thresholdPrecision, but the other one is not.

Specified by:

tryMerge in class InstantPatternDynamicFormatter.PatternSequence

Parameters:

other - A pattern sequence.

thresholdPrecision - A precision threshold to determine effectively constant sequences. This prevents merging effectively constant and dynamic pattern sequences.

Returns:

A merged formatter factory or null if merging is not possible.
