get(collection, key, default)

Return the value stored for the given key, or the given default value if no mapping for the key is present.

Examples

julia> d = Dict("a"=>1, "b"=>2);

julia> get(d, "a", 3)
1

julia> get(d, "c", 3)
3

get(f::Union{Function, Type}, collection, key)

Return the value stored for the given key, or if no mapping for the key is present, return f(). Use get! to also store the default value in the dictionary.

This is intended to be called using do block syntax

get(dict, key) do
    # default value calculated here
    time()
end

get(x::Nullable[, y])

Attempt to access the value of x. Returns the value if it is present; otherwise, returns y if provided, or throws a NullException if not.

Examples

julia> get(Nullable(5))
5

julia> get(Nullable())
ERROR: NullException()
Stacktrace:
 [1] get(::Nullable{Union{}}) at ./nullable.jl:102

get(sd,k,v)

Returns the value associated with key k where sd is a SortedDict, or else returns v if k is not in sd. Time: O(c log n)

get(collection, key, default)

Return the value stored for the given key, or the given default value if no mapping for the key is present.

Examples

julia> d = RobinDict("a"=>1, "b"=>2);

julia> get(d, "a", 3)
1

julia> get(d, "c", 3)
3

get(f::Function, collection, key)

Return the value stored for the given key, or if no mapping for the key is present, return f(). Use get! to also store the default value in the dictionary.

This is intended to be called using do block syntax

get(dict, key) do
    # default value calculated here
    time()
end

get(collection, key, default)

Return the value stored for the given key, or the given default value if no mapping for the key is present.

Examples

julia> d = OrderedRobinDict("a"=>1, "b"=>2);

julia> get(d, "a", 3)
1

julia> get(d, "c", 3)
3
