Method Detail

valueOf

public static Maturity valueOf(java.lang.String toParse)

Creates a maturity from a string representation. The general format is x[-,' ']?[DAYS, MONTHS, YEARS], where x is an int. Examples are:

• "30 d", "30 days", "30 day", "2d", "6-d"
• "6 m", "6 month", "6 months", "2m", "6-months"
• "3 y", "3 year", "3 years", "2y", "6-year"

As can be seen, days, months, and years can be parsed from either a single character or the full name.

Parameters:

toParse -

Returns:

maturity instance

hashCode

public int hashCode()

Overrides hashCode, because equals was overwritten. The algorithm was taken from (Joshua Bloch, "Effective Java", Item 8) .

Overrides:

hashCode in class java.lang.Object

Returns:

hash code

equals

public boolean equals(java.lang.Object o)

Overrides equals to provide logical comparison of two different Maturity objects.

Overrides:

equals in class java.lang.Object

Parameters:

o - object to compare with

Returns:

true if COUNT and UNIT are the same, false otherwise

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object
