Method Detail

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class Sha256Hash

getString

public java.lang.String getString()

toString

public java.lang.String toString()

Overrides:

toString in class Sha256Hash

hashCode

public int hashCode()

Description copied from class: Sha256Hash

Returns the last four bytes of the wrapped hash. This should be unique enough to be a suitable hash code even for blocks, where the goal is to try and get the first bytes to be zeros (i.e. the value as a big integer lower than the target value).

Overrides:

hashCode in class Sha256Hash

compareTo

public int compareTo(Sha256Hash other)

Specified by:

compareTo in interface java.lang.Comparable<Sha256Hash>

Overrides:

compareTo in class Sha256Hash

getNum

public long getNum()
