Constructor Detail

SimpleBindings

public SimpleBindings()

Constructs a SimpleNamespace.

SimpleBindings

public SimpleBindings(java.util.Map map)

Constructs a SimpleNamespace and initializes it using a specified map.

Parameters:

map - a map which is used to initialize the SimpleNamespace

Method Detail

put

public java.lang.Object put(java.lang.Object key,
                            java.lang.Object value)
                     throws java.lang.IllegalArgumentException

Associates the specified value with the specified key in a java.util.Map. If the map previously contained a mapping for this key, the old value is replaced.

Specified by:

put in interface java.util.Map

Specified by:

put in interface Bindings

Parameters:

key - the String value which uniquely identifies the object

value - the object to be stored.

Returns:

The old object

Throws:

java.lang.IllegalArgumentException - if the key is null or is not java.lang.String type

putAll

public void putAll(java.util.Map toMerge)
            throws java.lang.IllegalArgumentException

Copies all of the mappings from the specified map to this map. These mappings will replace any mappings that this map had for any of the keys currently in the specified map.

Specified by:

putAll in interface java.util.Map

Specified by:

putAll in interface Bindings

Parameters:

toMerge - mappings to be stored in the map.
