Method Detail

addElement

void addElement(RVMMethod item)

addUniqueElement

public void addUniqueElement(RVMMethod item)

Adds an item if it is not already in the vector. The test for the item uses object identity.

Parameters:

item - method to be added

elementAt

RVMMethod elementAt(int index)

setElementAt

void setElementAt(RVMMethod item,
                  int index)

size

public int size()

finish

public RVMMethod[] finish()

Returns:

an array of methods, trimmed to size. The returned array is canonical: Adding the same set of methods in the same order to different newly-created vectors v1 and v2 will lead to the same array being returned for both v1 and v2 when this method is called.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

adjustLength

private void adjustLength(int newLength)
