  - equals
```
public boolean equals(Object other)
```
    Description copied from class: java.lang.Object
    Indicates whether some other object is "equal to" this one.
    The equals method implements an equivalence relation on non-null object references:
    - It is reflexive: for any non-null reference value x, x.equals(x) should return true.
    - It is symmetric: for any non-null reference values x and y, x.equals(y) should return true if and only if y.equals(x) returns true.
    - It is transitive: for any non-null reference values x, y, and z, if x.equals(y) returns true and y.equals(z) returns true, then x.equals(z) should return true.
    - It is consistent: for any non-null reference values x and y, multiple invocations of x.equals(y) consistently return true or consistently return false, provided no information used in equals comparisons on the objects is modified.
    - For any non-null reference value x, x.equals(null) should return false.
    The equals method for class Object implements the most discriminating possible equivalence relation on objects; that is, for any non-null reference values x and y, this method returns true if and only if x and y refer to the same object (x == y has the value true).
    Note that it is generally necessary to override the hashCode method whenever this method is overridden, so as to maintain the general contract for the hashCode method, which states that equal objects must have equal hash codes.
    Specified by:
    
    equals in interface Map<String,Object>
    
    Overrides:
    
    equals in class Object
    
    Parameters:
    
    other - the reference object with which to compare.
    
    Returns:
    
    true if this object is the same as the obj argument; false otherwise.

    Object.hashCode(), HashMap
  - hashCode
```
public int hashCode()
```
    Description copied from class: java.lang.Object
    Returns a hash code value for the object. This method is supported for the benefit of hash tables such as those provided by HashMap.
    The general contract of hashCode is:
    - Whenever it is invoked on the same object more than once during an execution of a Java application, the hashCode method must consistently return the same integer, provided no information used in equals comparisons on the object is modified. This integer need not remain consistent from one execution of an application to another execution of the same application.
    - If two objects are equal according to the equals(Object) method, then calling the hashCode method on each of the two objects must produce the same integer result.
    - It is not required that if two objects are unequal according to the Object.equals(java.lang.Object) method, then calling the hashCode method on each of the two objects must produce distinct integer results. However, the programmer should be aware that producing distinct integer results for unequal objects may improve the performance of hash tables.
    As much as is reasonably practical, the hashCode method defined by class Object does return distinct integers for distinct objects. (This is typically implemented by converting the internal address of the object into an integer, but this implementation technique is not required by the Java™ programming language.)
    Specified by:
    
    hashCode in interface Map<String,Object>
    
    Overrides:
    
    hashCode in class Object
    
    Returns:
    
    a hash code value for this object.

    Object.equals(java.lang.Object), System.identityHashCode(java.lang.Object)
  - toString
```
public String toString()
```
    Description copied from class: java.lang.Object
    Returns a string representation of the object. In general, the toString method returns a string that "textually represents" this object. The result should be a concise but informative representation that is easy for a person to read. It is recommended that all subclasses override this method.
    The toString method for class Object returns a string consisting of the name of the class of which the object is an instance, the at-sign character `@', and the unsigned hexadecimal representation of the hash code of the object. In other words, this method returns a string equal to the value of:
    getClass().getName() + '@' + Integer.toHexString(hashCode())
    Overrides:
    
    toString in class Object
    
    Returns:
    
    a string representation of the object.

  - clear
```
public void clear()
```
    Description copied from interface: java.util.Map
    
    Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.
    
    Specified by:
    
    clear in interface Map<String,Object>
  - containsKey
```
public boolean containsKey(Object key)
```
    Description copied from interface: javax.script.Bindings
    
    Returns true if this map contains a mapping for the specified key. More formally, returns true if and only if this map contains a mapping for a key k such that (key==null ? k==null : key.equals(k)). (There can be at most one such mapping.)
    
    Specified by:
    
    containsKey in interface Map<String,Object>
    
    Specified by:
    
    containsKey in interface Bindings
    
    Parameters:
    
    key - key whose presence in this map is to be tested.
    
    Returns:
    
    true if this map contains a mapping for the specified key.
  - containsValue
```
public boolean containsValue(Object value)
```
    Description copied from interface: java.util.Map
    
    Returns true if this map maps one or more keys to the specified value. More formally, returns true if and only if this map contains at least one mapping to a value v such that (value==null ? v==null : value.equals(v)). This operation will probably require time linear in the map size for most implementations of the Map interface.
    
    Specified by:
    
    containsValue in interface Map<String,Object>
    
    Parameters:
    
    value - value whose presence in this map is to be tested
    
    Returns:

  - entrySet
```
public Set<Map.Entry<String,Object>> entrySet()
```
    Description copied from interface: java.util.Map
    
    Returns a Set view of the mappings contained in this map. The set is backed by the map, so changes to the map are reflected in the set, and vice-versa. If the map is modified while an iteration over the set is in progress (except through the iterator's own remove operation, or through the setValue operation on a map entry returned by the iterator) the results of the iteration are undefined. The set supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Set.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.
    
    Specified by:
    
    entrySet in interface Map<String,Object>
    
    Returns:
    
    a set view of the mappings contained in this map
  - get
```
public Object get(Object key)
```
    Description copied from interface: javax.script.Bindings
    
    Returns the value to which this map maps the specified key. Returns null if the map contains no mapping for this key. A return value of null does not necessarily indicate that the map contains no mapping for the key; it's also possible that the map explicitly maps the key to null. The containsKey operation may be used to distinguish these two cases.
    More formally, if this map contains a mapping from a key k to a value v such that (key==null ? k==null : key.equals(k)), then this method returns v; otherwise it returns null. (There can be at most one such mapping.)
    
    Specified by:
    
    get in interface Map<String,Object>
    
    Specified by:
    
    get in interface Bindings
    
    Parameters:
    
    key - key whose associated value is to be returned.

    Specified by:
    
    put in interface Bindings
    
    Parameters:
    
    key - The name associated with the value.
    
    value - The value associated with the name.
    
    Returns:
    
    The value previously associated with the given name. Returns null if no value was previously associated with the name.
  - putAll
```

    Specified by:
    
    putAll in interface Bindings
    
    Parameters:
    
    map - The Map to merge with this one.
  - remove
```
public Object remove(Object key)
```
    Description copied from interface: javax.script.Bindings
    
    Removes the mapping for this key from this map if it is present (optional operation). More formally, if this map contains a mapping from key k to value v such that (key==null ? k==null : key.equals(k)), that mapping is removed. (The map can contain at most one such mapping.)
    Returns the value to which the map previously associated the key, or null if the map contained no mapping for this key. (A null return can also indicate that the map previously associated null with the specified key if the implementation supports null values.) The map will not contain a mapping for the specified key once the call returns.
    
    Specified by:
    
    remove in interface Map<String,Object>
    
    Specified by:
    
    remove in interface Bindings
    
    Parameters:
