Method Detail
-
coerceValue
public final Object coerceValue(IType typeToCoerceTo, Object value)
- Specified by:
coerceValue
in interfaceICoercer
-
handlesNull
public boolean handlesNull()
- Specified by:
handlesNull
in interfaceICoercer
- Overrides:
handlesNull
in classStandardCoercer
- Returns:
- true if this coercer knows how to handle the null value.
-
resolveType
public IType resolveType(IType target, IType source)
Description copied from interface:IResolvingCoercer
This method should produce a more appropriately parameterized type for the given target type for this coercion. This allows a coercion to communicate type information through the coercion process. An example is the MetaType-to-Class coercion. MetaType
should be interpreted as Class from a type inference perspective, so this give the coercer a chance to let the compiler know so. If no more appropriate inference type exists, this method should return the source type.
- Specified by:
resolveType
in interfaceIResolvingCoercer
- Parameters:
target
- type- Returns:
- a possibly more appropriately parameterized type or the source type if not
-
getPriority
public int getPriority(IType to, IType from)
- Specified by:
getPriority
in interfaceICoercer
- Overrides:
getPriority
in classStandardCoercer
- 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.
