All known Subclasses:   org.jfree.data.xy .XYIntervalDataItem,  org.jfree.data.time.ohlc .OHLCItem,  org.jfree.data.xy .YIntervalDataItem,  org.jfree.data.xy .XIntervalDataItem,  org.jfree.data.xy .VectorDataItem,
ComparableObjectItem
public class ComparableObjectItem implements Cloneable,Comparable,Serializable(Code)
Represents one (Comparable, Object) data item for use in a ComparableObjectSeries .
since:
   1.0.3

Constructor Summary
public ComparableObjectItem(Comparable x, Object y)
     Constructs a new data item.

Method Summary
public Object clone()
     Returns a clone of this object.
public int compareTo(Object o1)
     Returns an integer indicating the order of this object relative to another object.
For the order we consider only the x-value: negative == "less-than", zero == "equal", positive == "greater-than".
Parameters:
  o1 - the object being compared to.
public boolean equals(Object obj)
     Tests if this object is equal to another.
Parameters:
  obj - the object to test against for equality (nullpermitted).
protected Comparable getComparable()
     Returns the x-value.
protected Object getObject()
     Returns the y-value.
public int hashCode()
     Returns a hash code.
protected void setObject(Object y)
     Sets the y-value for this data item.

Constructor Detail
ComparableObjectItem
public ComparableObjectItem(Comparable x, Object y)(Code)
Constructs a new data item.
Parameters:
  x - the x-value (null NOT permitted).
Parameters:
  y - the y-value (null permitted).

Method Detail
clone
public Object clone() throws CloneNotSupportedException(Code)
Returns a clone of this object. A clone.
throws:
  CloneNotSupportedException - not thrown by this class, but subclasses may differ.

public int compareTo(Object o1)(Code)
Returns an integer indicating the order of this object relative to another object.
For the order we consider only the x-value: negative == "less-than", zero == "equal", positive == "greater-than".
Parameters:
  o1 - the object being compared to. An integer indicating the order of this data pair objectrelative to another object.

equals
public boolean equals(Object obj)(Code)
Tests if this object is equal to another.
Parameters:
  obj - the object to test against for equality (nullpermitted). A boolean.

getComparable
protected Comparable getComparable()(Code)
Returns the x-value. The x-value (never null).

getObject
protected Object getObject()(Code)
Returns the y-value. The y-value (possibly null).

hashCode
public int hashCode()(Code)
Returns a hash code. A hash code.

setObject
protected void setObject(Object y)(Code)
Sets the y-value for this data item. Note that there is no corresponding method to change the x-value.
Parameters:
  y - the new y-value (null permitted).
