Assigns a new value to the hash:
hash = EscapeJavaProperties::Properties.new hash[:key] = 'value'
This value can be later fetched using either :key
or +'key'+.
Calls superclass method
# File lib/escape_java_properties/properties.rb, line 12 def []=(key, value) super(convert_key(key), value) end
delete(key)

Removes the specified key from the hash.
Calls superclass method
# File lib/escape_java_properties/properties.rb, line 51 def delete(key) super(convert_key(key)) end
fetch(key, *extras)

Same as Hash#fetch
where the key passed as argument can be either a string or a symbol:
counters = EscapeJavaProperties::Properties.new counters[:foo] = 1 counters.fetch('foo') # => 1 counters.fetch(:bar, 0) # => 0 counters.fetch(:bar) {|key| 0} # => 0 counters.fetch(:zoo) # => KeyError: key not found: "zoo"
Calls superclass method
# File lib/escape_java_properties/properties.rb, line 36 def fetch(key, *extras) super(convert_key(key), *extras) end
key?(key)

Checks the hash for a key matching the argument passed in:
hash = EscapeJavaProperties::Properties.new hash['key'] = 'value' hash.key?(:key) # => true hash.key?('key') # => true
Calls superclass method
# File lib/escape_java_properties/properties.rb, line 22 def key?(key) super(convert_key(key)) end
values_at(*indices)
click to toggle source
Returns an array of the values at the specified indices:
hash = EscapeJavaProperties::Properties.new hash[:a] = 'x' hash[:b] = 'y' hash.values_at('a', 'b') # => ["x", "y"]
# File lib/escape_java_properties/properties.rb, line 46 def values_at(*indices) indices.collect {|key| self[convert_key(key)]} end
