Class TrimToNullTrimmer

java.lang.Object

org.yarnandtail.andhow.property.TrimToNullTrimmer

All Implemented Interfaces:

Trimmer

public class TrimToNullTrimmer
extends Object
implements Trimmer

This trimmer trims to null. This is the default for all non-String Properties. String properties default to using the QuotedSpacePreservingTrimmer to allow whitespace to be preserved. A few examples of trimming behavior, using ... to represent whitespace and :: to separate the raw value on the left from the trimmed value on the right.

• ... :: [[null]] (An all whitespace raw value is trimmed to null)
• [[null]] :: [[null]]
• ...abc... :: abc (whitespace on either side of text removed)
• ..."...abc..."... :: "...abc..." (No special handing for quotes)
