java.lang.Objectorg.h2.value.CompareMode
public class CompareMode
Instances of this class can compare strings. Case sensitive and case insensitive comparison is supported, and comparison using a collator.
| Field Summary | |
|---|---|
static java.lang.String |
DEFAULT
This constant means the default collator should be used, even if ICU4J is in the classpath. |
static java.lang.String |
ICU4J
This constant means ICU4J should be used (this will fail if it is not in the classpath). |
static java.lang.String |
OFF
This constant means there is no collator set, and the default string comparison is to be used. |
static java.lang.String |
SIGNED
This constant means that the BINARY columns are sorted as if the bytes were signed. |
static java.lang.String |
UNSIGNED
This constant means that the BINARY columns are sorted as if the bytes were unsigned. |
