Method Detail

put

Object put(String attributeName,
         Object 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 putAll(AttributeMap 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 removeAll(MutableAttributeMap 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

Object remove(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

Object extract(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 clear()

Remove all attributes in this map.

Returns:

this, to support call chaining

replaceWith

MutableAttributeMap replaceWith(AttributeMap attributes)
                                throws 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:

UnsupportedOperationException
