Cling::Arguments

Inherits Struct < Value < Object

An input structure to access validated arguments at execution time.

Instance methods

[](key : String) : Argument

Indexes an argument by its name and returns the Argument object, not the argument's value.

Source

[]?(key : String) : Argument | Nil

Indexes an argument by its name and returns the Argument object or nil if not found, not the argument's value.

Source

empty?

Returns true if there are no parsed arguments.

Source

get(key : String) : Value

Gets an argument by its name and returns its Value.

Source

get?(key : String) : Value | Nil

Gets an argument by its name and returns its Value, or nil if not found.

Source

has?(key : String) : Bool

Returns true if an argument by the given name exists.

Source

hash

Generates an UInt64 hash value for this object.

This method must have the property that a == b implies a.hash == b.hash.

The hash value is used along with == by the Hash class to determine if two objects reference the same hash key.

Subclasses must not override this method. Instead, they must define hash(hasher), though usually the macro def_hash can be used to generate this method.

Source

size

Returns the number of parsed arguments.
