All Implemented Interfaces:

CoinSelector

Direct Known Subclasses:

AllowUnconfirmedCoinSelector
```
public class DefaultCoinSelector
extends java.lang.Object
implements CoinSelector
```
This class implements a CoinSelector which attempts to get the highest priority possible. This means that the transaction is the most likely to get confirmed. Note that this means we may end up "spending" more priority than would be required to get the transaction we are creating confirmed.

    tx - transaction to determine if it would be selected
    
    network - network the transaction is on
    
    Returns:
    
    true if it would be selected, false otherwise
