List of elementTypeDescriptor() Examples

Examples of elementTypeDescriptor()

org.springframework.core.convert.TypeDescriptor.elementTypeDescriptor()
If this type is a {@link Collection} or an Array, creates a element TypeDescriptor from the provided collection or array element.Narrows the {@link #getElementTypeDescriptor() elementType} property to the class of the provided collection or array element.For example, if this describes a java.util.List<java.lang.Number< and the element argument is a java.lang.Integer, the returned TypeDescriptor will be java.lang.Integer. If this describes a java.util.List<?> and the element argument is a java.lang.Integer, the returned TypeDescriptor will be java.lang.Integer as well. Annotation and nested type context will be preserved in the narrowed TypeDescriptor that is returned. @param element the collection or array element @return a element type descriptor, narrowed to the type of the provided element @throws IllegalStateException if this type is not a java.util.Collection or Array type @see #narrow(Object)

    // if the object is something that looks indexable by an integer, attempt to treat the index value as a number
    if (targetObject instanceof Collection || targetObject.getClass().isArray() || targetObject instanceof String) {
      int idx = (Integer) state.convertValue(index, TypeDescriptor.valueOf(Integer.class));
