Method Detail
-
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.
