compareTypeSafeback to summary
public final int compareTypeSafe(Value v, CompareMode mode, CastDataProvider provider)

Implements abstract org.h2.value.Value.compareTypeSafe.

Doc from org.h2.value.Value.compareTypeSafe.

Compare this value against another value given that the values are of the same data type.

Parameters
v:Value

the other value

mode:CompareMode

the compare mode

provider:CastDataProvider

the cast information provider

Returns:int

0 if both values are equal, -1 if the other value is smaller, and 1 otherwise

equalsback to summary
public final boolean equals(Object other)

Implements abstract org.h2.value.Value.equals.

Doc from org.h2.value.Value.equals.

Check if the two values have the same hash code. No data conversion is made; this method returns false if the other object is not of the same class. For some values, compareTo may return 0 even if equals return false. Example: ValueDecimal 0.0 and 0.00.

Parameters
other:Object

the other value

Returns:boolean

true if they are equal

@Override
hashCodeback to summary
public final int hashCode()

Implements abstract org.h2.value.Value.hashCode.

Doc from java.lang.Object.hashCode.

Returns a hash code value for this object. This method is supported for the benefit of hash tables such as those provided by java.util.HashMap.

The general contract of hashCode is:

  • Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
  • If two objects are equal according to the equals method, then calling the hashCode method on each of the two objects must produce the same integer result.
  • It is not required that if two objects are unequal according to the equals method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
Returns:int

a hash code value for this object
