Method Detail

instance

public static FunctionFromInterfaceCoercer instance()

handlesNull

public boolean handlesNull()

Returns:

true if this coercer knows how to handle the null value.

coerceValue

public Object coerceValue(IType typeToCoerceTo,
                          Object value)

doCoercion

public static Object doCoercion(Class classToCoerceTo,
                                Class ifaceClass,
                                Object value)

isExplicitCoercion

public boolean isExplicitCoercion()

areTypesCompatible

public static boolean areTypesCompatible(IFunctionType functionType,
                                         IType interfaceType)

getPriority

public int getPriority(IType to,
                       IType from)

Returns:

a value between 0 and MAX_PRIORITY, inclusive that indicates the priority of this coercer when resolving overloaded methods. Typically a coercer should return 0, but coercers that have a high affinity between the target and coerced type, such as primitives, can have higher priorities.
