public BaseDoubleEncodedValue()

Method Detail

hashCode

public int hashCode()

Description copied from interface: DoubleEncodedValue

Returns a hashcode for this EncodedDoubleValue. This hashCode is defined to be the following:

 
 long v = Double.doubleToRawLongBits(getValue());
 int hashCode = (int)(v^(v>>>32));
 

Note: This is slightly different than the definition of Double.hashCode(). This uses doubleToRawLongBits() instead of doubleToLongBits(), in order to preserve as much information as possible.

Specified by:

hashCode in interface DoubleEncodedValue

Overrides:

hashCode in class java.lang.Object

Returns:

The hash code value for this EncodedDoubleValue

equals

public boolean equals(@Nullable
                      java.lang.Object o)

Description copied from interface: DoubleEncodedValue

Compares this DoubleEncodedValue to another DoubleEncodedValue for equality. This DoubleEncodedValue is equal to another DoubleEncodedValue if the values returned by getValue().doubleToRawLongBits() are equal. Note: this isn't quite the same as getValue() == getValue(), due to various NaN issues and signed zero issues.

Specified by:

equals in interface DoubleEncodedValue

Overrides:

equals in class java.lang.Object

Parameters:

o - The object to be compared for equality with this DoubleEncodedValue

Returns:

true if the specified object is equal to this DoubleEncodedValue

compareTo

public int compareTo(@Nonnull
                     EncodedValue o)

Description copied from interface: DoubleEncodedValue

Compare this DoubleEncodedValue to another EncodedValue. The comparison is first done on the return values of getValueType(), and then if the other value is another DoubleEncodedValue, the return values of getValue() are compared, using the semantics of Double.compare()

Specified by:

compareTo in interface java.lang.Comparable<EncodedValue>

Specified by:

compareTo in interface DoubleEncodedValue

Parameters:

o - The EncodedValue to compare with this DoubleEncodedValue

Returns:

An integer representing the result of the comparison

getValueType

public int getValueType()

Description copied from interface: EncodedValue

Returns the type of this encoded value. The returned integer will be one of the ValueType.* constants.

Specified by:

getValueType in interface EncodedValue

Returns:

The type of this encoded value
