Instance Method Details

#exec(x, y, options = {}) ⇒ Boolean

Executes a less-or-equal operation.

Examples:

Executes less-or-equal operations with the default context

Groonga::Operator::LESS_EQUAL.exec(1, 1) # => true
Groonga::Operator::LESS_EQUAL.exec(1, 2) # => true
Groonga::Operator::LESS_EQUAL.exec(2, 1) # => false

Executes less-or-equal operations with the specified context

context = Groonga::Context.new
Groonga::Operator::LESS_EQUAL.exec(1, 1,
                                   :context => context) # => true
Groonga::Operator::LESS_EQUAL.exec(1, 2,
                                   :context => context) # => true
Groonga::Operator::LESS_EQUAL.exec(2, 1,
                                   :context => context) # => false

Returns true if x is less than or equal toy, 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 is less than or equal toy, false otherwise.
