Instance Method Details

#exec(x, y, options = {}) ⇒ Boolean

Executes a not-equal operation.

Examples:

Executes not-equal operations with the default context

Groonga::Operator::NOT_EQUAL.exec("hello", "Hello") # => true
Groonga::Operator::NOT_EQUAL.exec("hello", "hello") # => false

Executes not-equal operations with the specified context

context = Groonga::Context.new
Groonga::Operator::NOT_EQUAL.exec("hello", "Hello",
                                  :context => context) # => true
Groonga::Operator::NOT_EQUAL.exec("hello", "hello",
                                  :context => context) # => false

Returns true if x does not equal to y, false otherwise.

Parameters:

  • x (::Object) —

    The left hand side value.

  • y (::Object) —

    The right hand side value.

  • options (::Hash) (defaults to: {}) —

    The options.

Options Hash (options):

  • (Groonga::Context.default) (Groonga::Context) —

    The context to executes the operation.

Returns:

  • (Boolean) —

    true if x does not equal to y, false otherwise.
