evaluate

public <T> T evaluate(Object feature,
                      Class<T> context)

Description copied from class: ExpressionAbstract

Default implementation delegates handling of context conversion to Converters utility class.

Subclasses are expected to make use of the Converters utility class (as the easiest way to provide value morphing in conformance with the Filter specification).

Specified by:

evaluate in interface Expression

Overrides:

evaluate in class ExpressionAbstract

Type Parameters:

T - The type of the returned object.

Parameters:

feature - The object to evaluate the expression against.

context - The type of the resulting value of the expression.

Returns:

Evaluates the given expression based on the content of the given object an an instance of context.
