Constructor Details

GMP

public GMP()
The basic constructor. Object is special, because it has no superclass, so there is no call to super().

Method Details

abs

public void abs(GMP r)

absIntValue

public int absIntValue()

add

public void add(GMP x,
                GMP r)

and

public void and(GMP x,
                GMP r)

andNot

public void andNot(GMP x,
                   GMP r)

bitCount

public int bitCount()

bitLength

public int bitLength()

compare

public int compare(GMP x)

doubleValue

public double doubleValue()

finalize

protected void finalize()
Called on an object by the Virtual Machine at most once, at some point after the Object is determined unreachable but before it is destroyed. You would think that this means it eventually is called on every Object, but this is not necessarily the case. If execution terminates abnormally, garbage collection does not always happen. Thus you cannot rely on this method to always work. For finer control over garbage collection, use references from the java.lang.ref package.

Virtual Machines are free to not call this method if they can determine that it does nothing important; for example, if your class extends Object and overrides finalize to do simply super.finalize().

finalize() will be called by a Thread that has no locks on any Objects, and may be called concurrently. There are no guarantees on the order in which multiple objects are finalized. This means that finalize() is usually unsuited for performing actions that must be thread-safe, and that your implementation must be use defensive programming if it is to always work.

If an Exception is thrown from finalize() during garbage collection, it will be patently ignored and the Object will still be destroyed.

It is allowed, although not typical, for user code to call finalize() directly. User invocation does not affect whether automatic invocation will occur. It is also permitted, although not recommended, for a finalize() method to "revive" an object by making it reachable from normal code again.

Unlike constructors, finalize() does not get called for an object's superclass unless the implementation specifically calls super.finalize().

The default implementation does nothing.
