HArray
public HArray(java.lang.String line)
- Constructs a new HArray object from a line read from a heap profile. This
line is assumed to be a line beginning with ARR and containing the length
and type information for this array.
- Parameters:
line
- a line from a heap profile describing an array.
getMembers
public java.util.Iterator getMembers()
- Returns the set of vertices which are succesors of this one.
- Overrides:
- getMembers in class HVertex
- Returns:
- the set of vertices which are succesors of this one.
addMember
public void addMember(java.lang.String line)
- Adds a new element to the array. This is expected to be a line containing
the index and pointer to another HVertex object.
- Overrides:
- addMember in class HVertex
- Parameters:
line
- an array member line from a heap profile.
resolve
public void resolve(java.util.HashMap heap)
- Resolves the references contained in this array to actual HVertex objects.
- Overrides:
- resolve in class HVertex
- Parameters:
heap
- a HashMap containing all of the objects from the heap profile.
getNElems
public int getNElems()
- Returns the runtime length of this array. Note that the value returned by
this method may be different than the actual number of members contained
in this representation. This representation only contains members that
are non-null;
- Returns:
- the runtime length of this array.
size
public int size()
- Returns the number of members contained in this array. Only non-null
members are included.
- Returns:
- the number of members contained in this array.
getMember
public HVertex getMember(int i)
- Returns a specific member of this array. Calling this method is similar
to using the indexing operator at runtime.
- Parameters:
i
- the index into the array.- Returns:
- the HVertex contained in index
i
.
