cling/argument.crInstance Method Summary
-
#[](key : String) : Argument
Indexes an argument by its name and returns the
Argumentobject, not the argument's value. -
#[]?(key : String) : Argument | Nil
Indexes an argument by its name and returns the
Argumentobject ornilif not found, not the argument's value. -
#empty? : Bool
Returns
trueif there are no parsed arguments. -
#get(key : String) : Value
Gets an argument by its name and returns its
Value. -
#get?(key : String) : Value | Nil
Gets an argument by its name and returns its
Value, ornilif not found. -
#has?(key : String) : Bool
Returns
trueif an argument by the given name exists. -
#hash : Hash(String, Argument)
Generates an
UInt64hash value for this object. -
#size : Int32
Returns the number of parsed arguments.
Instance Method Detail
Indexes an argument by its name and returns the Argument object, not the argument's
value.
Indexes an argument by its name and returns the Argument object or nil if not found,
not the argument's value.
Gets an argument by its name and returns its Value, or nil if not found.
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.
