HObject
public HObject(java.lang.String line)
- Constructs a new HObject object from a line read from a heap profile. This
line is assumed to be a line beginning with OBJ and containing the type
type information for this object.
- Parameters:
line
- a line from a heap profile describing an object.
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 object. This is expected to be a line containing
the member name and pointer to another HVertex object.
- Overrides:
- addMember in class HVertex
- Parameters:
line
- an object member line from a heap profile.
resolve
public void resolve(java.util.HashMap heap)
- Resolves the references contained in this object to actual HVertex objects.
- Overrides:
- resolve in class HVertex
- Parameters:
heap
- a HashMap containing all of the objects from the heap profile.
getMemberNames
public java.util.Iterator getMemberNames()
- Returns an iterator containing the names of the members for this object.
- Returns:
- an iterator containing the names of the members for this object.
getMember
public HVertex getMember(java.lang.Object o)
- Find and returns the value of a member of this object. This version is
provided so that the iterator of member names may be used directly without
casting to index into an object. The object parameter is expected to be
of type String. If an object of any other type is passed in, or the
requested member is not found, the return value will be the
null
reference.
- Parameters:
o
- the name of a member of this object.- Returns:
- the object referred to by the requested member, null if not found.
getMember
public HVertex getMember(java.lang.String name)
- Find and returns the value of a member of this object. If a member with the
requested name is not found, the return value will be the
null
reference.
- Parameters:
name
- the name of a member of this object.- Returns:
- the object referred to by the requested member, null if not found.
