Usage

From source file:therian.operator.ELCoercionConverter.java

public boolean supports(Convert<?, ?> operation) {
    final Class<?> rawTargetType = getRawTargetType(operation);
    final Class<?> useTargetType = ObjectUtils.defaultIfNull(ClassUtils.primitiveToWrapper(rawTargetType),
            rawTargetType);/*from   ww w . j  av a 2 s. c o m*/

    // per UEL spec v2.2 section 1.18:
    if (String.class.equals(useTargetType)) {
        return true;
    }
    final Object source = operation.getSourcePosition().getValue();

    if (BigDecimal.class.equals(useTargetType) || BigInteger.class.equals(useTargetType)
            || Number.class.isAssignableFrom(useTargetType)
                    && ClassUtils.wrapperToPrimitive(useTargetType) != null) {
        return source == null || source instanceof String || source instanceof Character
                || source instanceof Number;
    }
    if (Character.class.equals(useTargetType)) {
        return source == null || source instanceof String || source instanceof Number;
    }
    if (Boolean.class.equals(useTargetType)) {
        return source == null || source instanceof String;
