PropertyTypeConverter (Alfresco Repository)

All Known Implementing Classes:

DefaultPropertyTypeConverter
```
public interface PropertyTypeConverter
```
Interface for converters that to translate between persisted values and external values.
Implementations must be able to convert between values being stored and Long, Double, String - and back again.

Since:

3.2

Method Summary

Methods
Modifier and Type	Method and Description
`java.io.Serializable`	`constructInstance(java.lang.String clazzName)` Construct an instance of an object that was deemed to be `PropertyValueEntity.PersistedType.CONSTRUCTABLE`.
`java.lang.Object`	`convert(java.lang.Class targetClass, java.io.Serializable value)` Convert a value to a given type.
`PropertyValueEntity.PersistedType`	`getPersistentType(java.io.Serializable value)` When external to persisted type mappings are not obvious, the persistence framework, before persisting as `PropertyValueEntity.PersistedType.SERIALIZABLE`, will give the converter a chance to choose how the value must be persisted: `PropertyValueEntity.PersistedType.LONG` `PropertyValueEntity.PersistedType.DOUBLE` `PropertyValueEntity.PersistedType.STRING` `PropertyValueEntity.PersistedType.SERIALIZABLE` `PropertyValueEntity.PersistedType.CONSTRUCTABLE` The converter should return `PropertyValueEntity.PersistedType.SERIALIZABLE` if no further conversions are possible.

  - getPersistentType
```
PropertyValueEntity.PersistedType getPersistentType(java.io.Serializable value)
```
    When external to persisted type mappings are not obvious, the persistence framework, before persisting as PropertyValueEntity.PersistedType.SERIALIZABLE, will give the converter a chance to choose how the value must be persisted:
    The converter should return PropertyValueEntity.PersistedType.SERIALIZABLE if no further conversions are possible. Implicit in the return value is the converter's ability to do the conversion when required.
    If the converter can fully reconstruct an equal instance using just the name of the value's class, then PropertyValueEntity.PersistedType.CONSTRUCTABLE can be used.
    Parameters:
    value - the value that does not have an obvious persistence slot
    
    Returns:
    Returns the type of persistence to use
  - convert
```
java.lang.Object convert(java.lang.Class targetClass,
                       java.io.Serializable value)
```
    Convert a value to a given type.
    
    Parameters:
    targetClass - the desired type to convert to
    value - the value to convert
    
    Returns:
    Returns the persisted type and value to persist
  - constructInstance
```
java.io.Serializable constructInstance(java.lang.String clazzName)
```
    Construct an instance of an object that was deemed to be PropertyValueEntity.PersistedType.CONSTRUCTABLE.
    
    Parameters:
    clazzName - the name of the class
    
    Returns:
    Returns the new instance
