Method Details

retrieveFrom

public static <T> void retrieveFrom(ImmutablePathTable<T> aFromPathTable,
 String aFromPath,
 PathTable<T> aToPathTable)

Hook method for implementing the ImmutablePathTable.retrieveFrom(String) method.

Type Parameters:

T - The type of the ImmutablePathTable the functionality is to be applied to.

Parameters:

aFromPathTable - The ImmutablePathTable from which to retrieve.

aFromPath - The path from where to start extracting the paths.

aToPathTable - The PathTable which to put the result in.

retrieveTo

public static <T> void retrieveTo(ImmutablePathTable<T> aFromPathTable,
 String aToPath,
 PathTable<T> aToPathTable)

Hook method for implementing the ImmutablePathTable.retrieveTo(String) method.

Type Parameters:

T - The type of the ImmutablePathTable the functionality is to be applied to.

Parameters:

aFromPathTable - The ImmutablePathTable from which to retrieve.

aToPath - The path where to relocate the paths of this ImmutablePathTable to.

aToPathTable - The PathTable which to put the result in.

toDataStructure

public static Object toDataStructure(ImmutablePathTable<?> aPathTable,
 String aFromPath)

Hook method for implementing the ImmutablePathTable.toDataStructure() method.

The org.refcodes.runtime.SystemProperty#STRUCT_KEEP_MAPS "struct.keepMaps" as well as the org.refcodes.runtime.EnvironmentVariable#STRUCT_KEEP_MAPS "STRUCT_KEEPMAPS" can be used to disable the conversion of Map instances into arrays by setting it to true (system property beats environment variable).

Parameters:

aPathTable - The ImmutablePathTable from which to get the data structure.

aFromPath - The path below which the ImmutablePathTable to be converted into a data structure.

Returns:

A data structure being a mixture of Map instances and arrays representing the data below the given path.

toGenericPath

public static String toGenericPath(ImmutablePathTable<?> aPathTable,
 String aPath)

Normalizes the path as of ImmutablePathTable.toNormalizedPath(String) and unifies it so that a path never ends with a delimiter (DelimiterAccessor.getDelimiter()). This is necessary as the root path is represented just by the delimiter, meaning that it also ends with the delimiter, though generic operations may require that a path must not end with the delimiter. This means that the root path is an empty String.

Parameters:

aPathTable - The ImmutablePathTable for which to unify the path.

aPath - The path to be unified.

Returns:

The resulting generic path never ending with a delimiter.
