Method: Weak::Map#delete

Defined in:
lib/weak/map.rb

#delete(key = UNDEFINED) {|key| ... } ⇒ Object?

Note:

Weak::Map does not test member equality with == or eql?. Instead, it always checks strict object equality, so that, e.g., different String keys are not considered equal, even if they may contain the same content.

Deletes the key-value pair and returns the value from self whose key is equal to key. If the key is not found, it returns nil. If the optional block is given and the key is not found, pass in the key and return the result of the block.

Parameters:

  • key (Object) (defaults to: UNDEFINED)

    the key to delete

Yields:

  • (key)

Yield Parameters:

  • key (Object)

    the given key if it was not part of the map

Returns:

  • (Object, nil)

    the value associated with the given key, or the result of the optional block if given the key was not found, or nil if the key was not found and no block was given.
