Interface DataTypeAnalyzer

All Known Implementing Classes:

AnnotationDataTypeAnalyzer, DefaultDataTypeAnalyzer

public interface DataTypeAnalyzer

Used by BeanModelSource to identify the type of data associated with a particular property (represented as a PropertyAdapter). The data type is a string used to determine what kind of interface to use for displaying the value of the property, or what kind of interface to use for editing the value of the property. Common property types are "text", "enum", "checkbox", but the list is extensible.

Different strategies for identifying the data type are encapsulated in the DataTypeAnalyzer service, forming a chain of command.
