• CorruptData

getSections

public Iterator getSections()

Description copied from interface: JavaHeap

Get the set of contiguous memory regions which form this heap.

Specified by:

getSections in interface JavaHeap

Returns:

an iterator over the collection of contiguous memory regions which form this heap

• CorruptData

equals

public boolean equals(Object obj)

Description copied from class: java.lang.Object

Compares the argument to the receiver, and answers true if they represent the same object using a class specific comparison. The implementation in Object answers true only if the argument is the exact same object as the receiver (==).

Specified by:

equals in interface JavaHeap

Overrides:

equals in class Object

Parameters:

obj -

Returns:

True if the given object refers to the same Java Heap in the image

See Also:

• Object.hashCode()

hashCode

public int hashCode()

Description copied from class: java.lang.Object

Answers an integer hash code for the receiver. Any two objects which answer true when passed to .equals must answer the same value for this method.

Specified by:

hashCode in interface JavaHeap

Overrides:

hashCode in class Object

Returns:

the receiver's hash.
