Returns:

the composite or null if not exists or is empty

Throws:

BadDataPathCardinalityException - if the value of a part of the data path is multiple. Only the last part can be multiple

IllegalArgumentException - if the given composite path is null or empty

BadItemTypeException - if the stored value at the given path is not a composite

hasValue

boolean hasValue(String dataPath)
          throws IllegalArgumentException,
BadDataPathCardinalityException

Checks if there is a non empty value for the data at the given path

Specified by:

hasValue in interface DataHolder

Parameters:

dataPath - path of the data

Returns:

true if there is a non empty value for the data, false otherwise

Throws:

BadDataPathCardinalityException - if the value of a part of the data path is multiple. Only the last part can be multiple

getValue

<T> T getValue(String dataPath)
        throws IllegalArgumentException,
UnknownTypeException,
NotUniqueTypeException,
BadDataPathCardinalityException

Retrieves the value of the data at the given path The type of the value will be deduced from the stored data. In some cases, the type can be wrong. For example, it is impossible to know if a stored date is a date or a date time

Type Parameters:

T - type of the value to retrieve. Should match the given data type

Parameters:

dataPath - path of the data

Returns:

the value of the data or null if not exists or is empty. The object returned may be of a generic class defined by the storage. For example, an url may be returned as a String. Use the 2 arguments version to ensure to get the right kind of Object.

Throws:

IllegalArgumentException - if the given data path is null or empty

UnknownTypeException - if there is no compatible type with the data at the given data path

NotUniqueTypeException - if there are many compatible types (there is no way to determine which type is the good one)

BadDataPathCardinalityException - if the value of a part of the data path is multiple. Only the last part can be multiple

Type Parameters:

Returns:

the value of the data, null if the data exists but is empty, or the given default value

Throws:

IllegalArgumentException - if the given data path is null or empty

UnknownTypeException - if there is no compatible type with the data at the given data path

NotUniqueTypeException - if there are many compatible types (there is no way to determine which type is the good one)
