Constructor Detail

Cascade

public Cascade()

Constructs a new Cascade.

Cascade

public Cascade(Cascade other)

Constructs a new Cascade from existing one.

Parameters:

other - other Cascade

Method Detail

get

public <T> T get(String key,
                 T def,
                 Class<T> klass)

Type Parameters:

T - the expected type

Parameters:

key - the key

def - default value, can be null

klass - the same as T

Returns:

if a value that can be converted to class klass has been mapped to key, returns this value, def otherwise

get

public <T> T get(String key,
                 T def,
                 Class<T> klass,
                 boolean suppressWarnings)

Get value for the given key

Type Parameters:

T - the expected type

Parameters:

key - the key

def - default value, can be null

klass - the same as T

suppressWarnings - show or don't show a warning when some value is found, but cannot be converted to the requested type

Returns:

if a value that can be converted to class klass has been mapped to key, returns this value, def otherwise

get

public Object get(String key)

Gets a property for the given key (like stroke, ...)

Parameters:

key - The key of the property

Returns:

The value or null if it is not set. May be of any type
