Method Detail

value

public double value()

toIntValue

public int toIntValue()

toString

public String toString()

Description copied from class: Value

Values must override the default method to return a string representation that is immutable.

Specified by:

toString in class Value

Returns:

String representation

hashCode

public int hashCode()

Description copied from class: Value

Values must override the default hashcode method.

Specified by:

hashCode in class Value

Returns:

int hashcode

equals

public boolean equals(Object obj)

Description copied from class: Value

Values must override the default equals method. This method should only return true if the supplied Object is of the same type as the implementing Value. Values of an unknown type should be coerced before calling this method. This method does not have to guarantee that this.equals(that) == this.toString().equals(that.toString())

Specified by:

equals in class Value

Returns:

boolean

equivalent

public boolean equivalent(Value arg)

Overrides:

equivalent in class Value

isEmpty

public boolean isEmpty()

Description copied from class: Value

Check whether this Value is an empty value and has a zero length string representation. Subclasses may wish to override this for efficiency if the String representation is lazily created.

Overrides:

isEmpty in class Value

Returns:

boolean true if empty

compareTo

public int compareTo(PNumber o)

Specified by:

compareTo in interface Comparable<PNumber>

isInteger

public boolean isInteger()

of

public static PNumber of(double val)

of

public static PNumber of(int val)

parse

public static PNumber parse(String str)
                     throws ValueFormatException

Throws:

ValueFormatException

from

public static Optional<PNumber> from(Value arg)

info

public static ArgumentInfo info()

info

public static ArgumentInfo info(double min,
                                double max)
