Class Equivalence.Builder

java.lang.Object

com.amazon.ion.util.Equivalence.Builder

Enclosing class:

Equivalence

public static final class Equivalence.Builder
extends java.lang.Object

Constructs Equivalence instances. To compare IonValues using an Equivalence instance's configuration, call Equivalence.ionValueEquals(IonValue, IonValue) on that instance rather than calling IonValue.equals(Object).

Method Detail

withStrict

public Equivalence.Builder withStrict(boolean isStrict)

When true, checks for strict data equivalence over two Ion Values. When false, checks for structural data equivalence over two Ion Values. See Equivalence for discussion of the differences between the two. Default: true.

Parameters:

isStrict - the value.

Returns:

this builder.

withEpsilon

public Equivalence.Builder withEpsilon(double epsilon)

The maximum absolute difference between two Ion float values for which the two values will be considered equivalent. Default: Ion float values will only be considered equivalent when Double.compare(a, b) == 0.

Parameters:

epsilon - the value.

Returns:

this builder.

withMaxComparisonDepth

public Equivalence.Builder withMaxComparisonDepth(int maxComparisonDepth)

The maximum depth to which two values will be compared. If the two values to be compared are still potentially equivalent beyond this depth, Equivalence.ionValueEquals(IonValue, IonValue) will throw an IonException.

Parameters:

maxComparisonDepth - the value.

Returns:

this builder.

build

public Equivalence build()

Returns:

a new Equivalence using this builder's configuration.
