Constant Field Values

Method Detail

coerceValue

Object coerceValue(IType typeToCoerceTo,
                   Object value)

isExplicitCoercion

boolean isExplicitCoercion()

handlesNull

boolean handlesNull()

Returns:

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

getPriority

int getPriority(IType to,
                IType from)

Parameters:

to -

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.
