javax.script.SimpleBindings — clojure-interop/javax.script 1.0.4

A simple implementation of Bindings backed by a HashMap or some other specified Map.

->simple-bindings clj

(->simple-bindings)

(->simple-bindings m)

Constructor.

Constructor uses an existing Map to store the values.

m - The Map backing this SimpleBindings. - java.util.Map

throws: java.lang.NullPointerException - if m is null

clear clj

(clear this)

Removes all of the mappings from this map (optional operation). The map will be empty after this call returns.

contains-key clj

(contains-key this 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.)

key - key whose presence in this map is to be tested. - java.lang.Object

returns: true if this map contains a mapping for the specified key. - boolean

throws: java.lang.NullPointerException - if key is null

contains-value clj

(contains-value this value)

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.

value - value whose presence in this map is to be tested - java.lang.Object

returns: true if this map maps one or more keys to the specified value - boolean

empty? clj

(empty? this)

Returns true if this map contains no key-value mappings.

returns: true if this map contains no key-value mappings - boolean

entry-set clj

(entry-set this)

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.

returns: a set view of the mappings contained in this map - java.util.Set<java.util.Map$Entry<java.lang.String,java.lang.Object>>

get clj

(get this 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.)

key - key whose associated value is to be returned. - java.lang.Object

returns: the value to which this map maps the specified key, or null if the map contains no mapping for this key. - java.lang.Object

throws: java.lang.NullPointerException - if key is null

key-set clj

(key-set this)

Returns a Set view of the keys 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), 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.

returns: a set view of the keys contained in this map - java.util.Set<java.lang.String>

put clj

(put this name value)

Sets the specified key/value in the underlying map field.

name - Name of value - java.lang.String value - Value to set. - java.lang.Object

returns: Previous value for the specified key. Returns null if key was previously unset. - java.lang.Object

throws: java.lang.NullPointerException - if the name is null.

put-all clj

(put-all this to-merge)

putAll is implemented using Map.putAll.

to-merge - The Map of values to add. - java.util.Map

throws: java.lang.NullPointerException - if toMerge map is null or if some key in the map is null.

remove clj

(remove this 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.

key - key whose mapping is to be removed from the map. - java.lang.Object

returns: previous value associated with specified key, or null if there was no mapping for key. - java.lang.Object

throws: java.lang.NullPointerException - if key is null

size clj

(size this)

Returns the number of key-value mappings in this map. If the map contains more than Integer.MAX_VALUE elements, returns Integer.MAX_VALUE.

returns: the number of key-value mappings in this map - int

values clj

(values this)

Returns a Collection view of the values contained in this map. The collection is backed by the map, so changes to the map are reflected in the collection, and vice-versa. If the map is modified while an iteration over the collection is in progress (except through the iterator's own remove operation), the results of the iteration are undefined. The collection supports element removal, which removes the corresponding mapping from the map, via the Iterator.remove, Collection.remove, removeAll, retainAll and clear operations. It does not support the add or addAll operations.

returns: a collection view of the values contained in this map - java.util.Collection<java.lang.Object>
