Member Function Documentation

is_empty()

abstract boolean aud.adt.AbstractStack< T >.is_empty ( )

abstract

Is stack empty?

Reimplemented in aud.Stack< T >.

Referenced by aud.adt.AbstractStack< T >.toString().

Here is the caller graph for this function:

pop()

abstract T aud.adt.AbstractStack< T >.pop ( )

abstract

Pop element from stack.

Requires !is_empty().

Exceptions

NoSuchElementException

Returns

removed element

Reimplemented in aud.example.VerboseStack< T >, and aud.Stack< T >.

Referenced by aud.adt.AbstractStack< T >.toString().

Here is the caller graph for this function:

push()

abstract void aud.adt.AbstractStack< T >.push ( T  x )

abstract

Push x onto stack.

Parameters

x	new element

Reimplemented in aud.example.VerboseStack< T >, and aud.Stack< T >.

Referenced by aud.adt.AbstractStack< T >.toString().

Here is the caller graph for this function:

top()

abstract T aud.adt.AbstractStack< T >.top ( )

abstract

Get stack top.

Requires !is_empty().

Exceptions

NoSuchElementException

Returns

top

Reimplemented in aud.Stack< T >.

toString()

String aud.adt.AbstractStack< T >.toString

(

)

Get string representation "|a|b|c".

(Here, "c" is stack top. "|" denotes empty stack.)

Reimplemented in aud.example.VerboseStack< T >.
