```
public class TriMap<T1,T2,T3>
extends java.lang.Object
```
TriMap is a triple-directional map. It is intended to hold items, T1, T2, and T3, that have a 1-1 relationship and it is desired to look up item T1 from T2 or T3, T2 from T1 or T2, or T3 from T1 or T2. If a new item is inserted that already exists in the map the add will fail

Modifier and Type	Method	Description
`void`	`addT1(T1 iT1, T2 iT2, T3 iT3)`	addT1 puts the iT1, iT2, and iT3 into the internal tri-maps. throws IllegalArgumentException if T1, T2, or T3 already exist in the map
`void`	`clear()`	clear will remove all entries in the tri-maps
`boolean`	`containsT1(T1 iT1)`	containsT1 return true is iT1 is in the tri-maps
`boolean`	`containsT2(T2 iT2)`	containsT2 return true is iT2 is in the tri-maps
`boolean`	`containsT3(T3 iT3)`	containsT2 return true is iT2 is in the tri-maps
`java.util.Set<TriMap.Entry<T1,T2,T3>>`	`entrySet()`	entrySet returns a Set of Entry objects from the tri-maps.

`boolean`	`isEmpty()`
`TriMap.Entry<T1,T2,T3>`	`removeByT1(T1 iT1)`	removeByT1 removes the entry in the tri-maps corresponding to iT1.
`TriMap.Entry<T1,T2,T3>`	`removeByT2(T2 iT2)`	removeByT2 removes the entry in the tri-maps corresponding to iT2.
`TriMap.Entry<T1,T2,T3>`	`removeByT3(T3 iT3)`	removeByT3 removes the entry in the tri-maps corresponding to iT3.

                  T3 iT3)
           throws java.lang.IllegalArgumentException
```
    addT1 puts the iT1, iT2, and iT3 into the internal tri-maps. throws IllegalArgumentException if T1, T2, or T3 already exist in the map
    
    Throws:

```
  - removeByT1
```
public TriMap.Entry<T1,T2,T3> removeByT1(T1 iT1)
```
    removeByT1 removes the entry in the tri-maps corresponding to iT1. Returns the entry of the map
  - removeByT2
```
public TriMap.Entry<T1,T2,T3> removeByT2(T2 iT2)
```
    removeByT2 removes the entry in the tri-maps corresponding to iT2. Returns the entry of the map
  - removeByT3
```
public TriMap.Entry<T1,T2,T3> removeByT3(T3 iT3)
```
    removeByT3 removes the entry in the tri-maps corresponding to iT3. Returns the entry of the map
  - size
```
public int size()
```
  - isEmpty
```
public boolean isEmpty()
```
  - containsT1
```
public boolean containsT1(T1 iT1)
```
    containsT1 return true is iT1 is in the tri-maps
  - containsT2
```
public boolean containsT2(T2 iT2)
```
    containsT2 return true is iT2 is in the tri-maps
  - containsT3
```
public boolean containsT3(T3 iT3)
```
    containsT2 return true is iT2 is in the tri-maps
  - clear
```
public void clear()
```
    clear will remove all entries in the tri-maps
  - entrySet
```
public java.util.Set<TriMap.Entry<T1,T2,T3>> entrySet()
```
    entrySet returns a Set of Entry objects from the tri-maps. It is intended to be used when iterating over the tri-maps. It works very similarly (same syntax) as the HashMap.entrySet(). However, the returned Set is independent of the contents of the tri-map. Thus, if you modify the returned Set, you will NOT modify the underlying tri-maps
