Constructor Detail

PriorityDelegatingCoercer

public PriorityDelegatingCoercer(ICoercer delegate,
                                 int priority)

Method Detail

coerceValue

public final Object coerceValue(IType typeToCoerceTo,
                                Object value)

isExplicitCoercion

public boolean isExplicitCoercion()

handlesNull

public boolean handlesNull()

Returns:

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

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.
