Method Detail

read

default Object read(RepositoryData parentData,
                    String name)
             throws BadItemTypeException

Description copied from interface: RepositoryElementType

Read the value in the given repository data

Specified by:

read in interface RepositoryElementType<T>

Parameters:

parentData - repository data containing the value

name - the name of the element to read

Returns:

the value. Can return a T or a T[]. That's why the return type is Object

Throws:

BadItemTypeException - if the reading value doesn't match this element type

hasNonEmptyValue

default boolean hasNonEmptyValue(RepositoryData parentData,
                                 String name)
                          throws BadItemTypeException

Description copied from interface: RepositoryModelItemType

Check if there is a non empty value in the given repository data

Specified by:

hasNonEmptyValue in interface RepositoryModelItemType

Parameters:

parentData - repository data containing the value

name - the name of the element to check

Returns:

true if there is a non empty value, false otherwise

Throws:

BadItemTypeException - if the reading value doesn't match this element type

isSingleValueEmpty

boolean isSingleValueEmpty(RepositoryData singleValueData)

Checks if the single value is empty

Parameters:

singleValueData - repository data containing the value to check

Returns:

true if the value is empty, false otherwise

readSingleValue

T readSingleValue(RepositoryData singleValueData)

Read the single value in the given repository data

Parameters:

singleValueData - repository data containing the value

Returns:

the value. Can return null if the given data does not contain the necessary elements

write

default void write(ModifiableRepositoryData parentData,
                   String name,
                   Object value)
            throws BadItemTypeException

Description copied from interface: RepositoryElementType

Write the value into the given repository data

Specified by:

write in interface RepositoryElementType<T>

Parameters:

parentData - repository where to store the value.

name - the name of the element to write

value - the value to write. Can be a T or a T[]. That's why it is an Object

Throws:

BadItemTypeException - If the given value doesn't match this element type

removeValueBeforeWritingIt

default boolean removeValueBeforeWritingIt()

Determines if the existing value has to be removed before writing the new one

Returns:

true if the previous value has to be removed, false otherwise

emptySingleValue

void emptySingleValue(ModifiableRepositoryData parentData,
                      String name)

Empties the single value into the given repositoryData This method is called by the write(ModifiableRepositoryData, String, Object) method, when the given value is null

Parameters:

parentData - repository where to empty the single value.

name - the name of the element to empty

writeSingleValue

void writeSingleValue(ModifiableRepositoryData parentData,
                      String name,
                      T value)

Write the single value into the given repository data This method is called by the write(ModifiableRepositoryData, String, Object) method, once for each value if the value is an array

Parameters:

parentData - repository where to store the single value.

name - the name of the element to write

value - the single value to write. Can be null. In this case, an empty data must be created

isCompatible

default boolean isCompatible(RepositoryData parentData,
                             String name)
                      throws UnknownDataException

Description copied from interface: RepositoryModelItemType

Checks if the value in the given repository data is compatible with the item type

Specified by:

isCompatible in interface RepositoryModelItemType

Parameters:

parentData - repository data containing the data to check

name - the name of the data to check

Returns:

true if the data type matches the current type, false otherwise

Throws:

UnknownDataException - if there is no data in the parent repository data with this name
