public interface MutableAttributeMap<V>
extends AttributeMap<V>

An interface for accessing and modifying attributes in a backing map with string keys.

Implementations can optionally support listeners that will be notified when they're bound in or unbound from the map.

Method Detail

put

V put(java.lang.String attributeName,
      V attributeValue)

Put the attribute into this map.

If the attribute value is an AttributeMapBindingListener this map will publish binding events such as on "bind" and "unbind" if supported.

Note: not all MutableAttributeMap implementations support this.

Parameters:

attributeName - the attribute name

attributeValue - the attribute value

Returns:

the previous value of the attribute, or null of there was no previous value

putAll

MutableAttributeMap<V> putAll(AttributeMap<? extends V> attributes)

Put all the attributes into this map.

Parameters:

attributes - the attributes to put into this map

Returns:

this, to support call chaining

removeAll

MutableAttributeMap<V> removeAll(MutableAttributeMap<? extends V> attributes)

Remove all attributes in the map provided from this map.

Parameters:

attributes - the attributes to remove from this map

Returns:

this, to support call chaining

remove

java.lang.Object remove(java.lang.String attributeName)

Remove an attribute from this map.

Parameters:

attributeName - the name of the attribute to remove

Returns:

previous value associated with specified attribute name, or null if there was no mapping for the name

extract

java.lang.Object extract(java.lang.String attributeName)

Extract an attribute from this map, getting it and removing it in a single operation.

Parameters:

attributeName - the attribute name

Returns:

the value of the attribute, or null of there was no value

clear

MutableAttributeMap<V> clear()

Remove all attributes in this map.

Returns:

this, to support call chaining

replaceWith

MutableAttributeMap<V> replaceWith(AttributeMap<? extends V> attributes)
                                   throws java.lang.UnsupportedOperationException

Replace the contents of this attribute map with the contents of the provided collection.

Parameters:

attributes - the attribute collection

Returns:

this, to support call chaining

Throws:

java.lang.UnsupportedOperationException
