Method Details

getCssConverter

public org.jhotdraw8.base.converter.Converter<CssDefaultableValue<T>> getCssConverter()

Specified by:

getCssConverter in interface ReadOnlyStyleableMapAccessor<T>

getInitialValue

public T getInitialValue()

Returns the initial value of the attribute.

We use the definition from CSS initial value:

"Each property has an initial value, defined in the property's definition table. If the property is not an inherited property, and the cascade does not result in a value, then the specified value of the property is its initial value."

We intentionally do not use the definition from SVG initial value:

"The initial value of an attribute or property is the value used when that attribute or property is not specified, or when it has an invalid value."
