      • clear

        public void clear()
        Specified by:
        clear in interface java.util.Map<java.lang.String,​java.lang.Object>

      • containsKey

        public boolean containsKey​(java.lang.Object key)
        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 javax.script.Bindings
        Specified by:
        containsKey in interface java.util.Map<java.lang.String,​java.lang.Object>
        Parameters:
        key - key whose presence in this map is to be tested.
        Returns:
        true if this map contains a mapping for the specified key.
        Throws:
        java.lang.NullPointerException - if key is null
        java.lang.ClassCastException - if key is not String
        java.lang.IllegalArgumentException - if key is empty String

      • containsValue

        public boolean containsValue​(java.lang.Object value)
        Specified by:
        containsValue in interface java.util.Map<java.lang.String,​java.lang.Object>

      • entrySet

        public java.util.Set<java.util.Map.Entry<java.lang.String,​java.lang.Object>> entrySet()
        Specified by:
        entrySet in interface java.util.Map<java.lang.String,​java.lang.Object>

      • get

        public java.lang.Object get​(java.lang.Object key)
        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 javax.script.Bindings
        Specified by:
        get in interface java.util.Map<java.lang.String,​java.lang.Object>
        Parameters:
        key - key whose associated value is to be returned.
        Returns:
        the value to which this map maps the specified key, or null if the map contains no mapping for this key.
        Throws:
        java.lang.NullPointerException - if key is null
        java.lang.ClassCastException - if key is not String
        java.lang.IllegalArgumentException - if key is empty String

      • isEmpty

        public boolean isEmpty()
        Specified by:
        isEmpty in interface java.util.Map<java.lang.String,​java.lang.Object>

      • keySet

        public java.util.Set<java.lang.String> keySet()
        Specified by:
        keySet in interface java.util.Map<java.lang.String,​java.lang.Object>

      • remove

        public java.lang.Object remove​(java.lang.Object key)
        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 javax.script.Bindings
        Specified by:
        remove in interface java.util.Map<java.lang.String,​java.lang.Object>
        Parameters:
        key - key whose mapping is to be removed from the map.
        Returns:
        previous value associated with specified key, or null if there was no mapping for key.
        Throws:
        java.lang.NullPointerException - if key is null
        java.lang.ClassCastException - if key is not String
        java.lang.IllegalArgumentException - if key is empty String
