Class Method Details

.dot_path(array, value) ⇒ Object

Takes an array of components that usually come from a dotted path such as foo.bar.baz, along with a value that is found at the end of that path, then converts it into a nested Hash with each level of the Hash corresponding to a step along the path.

This was written to help with edge case SCIM uses where (most often, at least) inbound calls use a dotted notation where nested values are more commonly accepted; converting to nesting makes it easier for subsequent processing code, which needs only handle nested Hash data.

As an example, passing:

['foo', 'bar', 'baz'], 'value'

…yields:

{'foo' => {'bar' => {'baz' => 'value'}}}

Parameters:

array

Array containing path components, usually acquired from a string with dot separators and a call to String#split.

value

The value found at the path indicated by array.

If array is empty, value is returned directly, with no nesting Hash wrapping it.
