1.116.6 Namespace: overrides for superspaces

associationAt: key ifAbsent: aBlock

Return the key/value pair associated to the variable named as specified by ‘key’. If the key is not found search will be brought on in superspaces, finally evaluating aBlock if the variable cannot be found in any of the superspaces.

associationsDo: aBlock

Pass each association in the namespace to aBlock

at: key ifAbsent: aBlock

Return the value associated to the variable named as specified by ‘key’. If the key is not found search will be brought on in superspaces, finally evaluating aBlock if the variable cannot be found in any of the superspaces.

at: key ifPresent: aBlock

If aKey is absent from the receiver and all its superspaces, answer nil. Else, evaluate aBlock passing the associated value and answer the result of the invocation

do: aBlock

Pass each value in the namespace to aBlock

includesKey: key

Answer whether the receiver or any of its superspaces contain the given key

keysAndValuesDo: aBlock

Pass to aBlock each of the receiver’s keys and values, in two separate parameters

keysDo: aBlock

Pass to aBlock each of the receiver’s keys

set: key to: newValue ifAbsent: aBlock

Assign newValue to the variable named as specified by ‘key’. This method won’t define a new variable; instead if the key is not found it will search in superspaces and evaluate aBlock if it is not found. Answer newValue.

size

Answer the number of keys in the receiver and each of its superspaces
