Constructor Detail

IdentityStack

public IdentityStack()
Default constructor.


IdentityStack

public IdentityStack(java.lang.Object o)
Construct a new IdentityStack with the specified Object as the bottom element.

Parameters:
o - the bottom element.
Method Detail

getInstance

public static IdentityStack getInstance(java.util.Stack s)
Get an IdentityStack containing the contents of the specified Stack.

Parameters:
s - the Stack to copy; ignored if null.
Returns:
an IdentityStack instance.

contains

public boolean contains(java.lang.Object o)
Override methods that use .equals() comparisons on elements.

Specified by:
contains in interface java.util.Collection
Specified by:
contains in interface java.util.List
Overrides:
contains in class java.util.Vector
Parameters:
o - the Object to search for.
