Class BoolStack
java.lang.Object
org.apache.xml.serializer.utils.BoolStack
public final class BoolStack
extends java.lang.Object
Simple stack for boolean values.
This class is a copy of the one in org.apache.xml.utils.
It exists to cut the serializers dependancy on that package.
A minor changes from that package are:
doesn't implement Clonable
This class is not a public API, it is only public because it is
used in org.apache.xml.serializer.
BoolStack() - Default constructor.
|
BoolStack(int size) - Construct a IntVector, using the given block size.
|
void | clear() - Clears the stack.
|
boolean | isEmpty() - Tests if this stack is empty.
|
boolean | peek() - Looks at the object at the top of this stack without removing it
from the stack.
|
boolean | peekOrFalse() - Looks at the object at the top of this stack without removing it
from the stack.
|
boolean | peekOrTrue() - Looks at the object at the top of this stack without removing it
from the stack.
|
boolean | pop() - Removes the object at the top of this stack and returns that
object as the value of this function.
|
boolean | popAndTop() - Removes the object at the top of this stack and returns the
next object at the top as the value of this function.
|
boolean | push(boolean val) - Pushes an item onto the top of this stack.
|
void | setTop(boolean b) - Set the item at the top of this stack
|
int | size() - Get the length of the list.

BoolStack
public BoolStack()
Default constructor. Note that the default
block size is very small, for small lists.
BoolStack
public BoolStack(int size)
Construct a IntVector, using the given block size.
size
- array size to allocate
clear
public final void clear()
Clears the stack.
isEmpty
public boolean isEmpty()
Tests if this stack is empty.
true
if this stack is empty;
false
otherwise.
peek
public final boolean peek()
Looks at the object at the top of this stack without removing it
from the stack.
- the object at the top of this stack.
peekOrFalse
public final boolean peekOrFalse()
Looks at the object at the top of this stack without removing it
from the stack. If the stack is empty, it returns false.
- the object at the top of this stack.
peekOrTrue
public final boolean peekOrTrue()
Looks at the object at the top of this stack without removing it
from the stack. If the stack is empty, it returns true.
- the object at the top of this stack.
pop
public final boolean pop()
Removes the object at the top of this stack and returns that
object as the value of this function.
- The object at the top of this stack.
popAndTop
public final boolean popAndTop()
Removes the object at the top of this stack and returns the
next object at the top as the value of this function.
- Next object to the top or false if none there
push
public final boolean push(boolean val)
Pushes an item onto the top of this stack.
val
- the boolean to be pushed onto this stack.
setTop
public final void setTop(boolean b)
Set the item at the top of this stack
b
- Object to set at the top of this stack
size
public final int size()
Get the length of the list.
- Current length of the list
