Class ExamplesTable

  • Direct Known Subclasses:

    public class ExamplesTable
    extends Object
    Represents a tabular structure that holds rows of example data for parameters named via the column headers:
     |header 1|header 2| .... |header n|
     |value 11|value 12| .... |value 1n|
     |value m1|value m2| .... |value mn|

    Different header and value column separators can be specified to replace the default separator "|":

     !!header 1!!header 2!! .... !!header n!!
     !value 11!value 12! .... !value 1n!
     !value m1!value m2| .... !value mn!

    Rows starting with an ignorable separator are allowed and ignored:

     |header 1|header 2| .... |header n|
     |-- A commented row --|
     |value 11|value 12| .... |value 1n|
     |-- Another commented row --|
     |value m1|value m2| .... |value mn|

    Ignorable separator is configurable and defaults to "|--".

    The separators are also configurable via inlined properties:

     !header 1!header 2! .... !header n!
     !-- A commented row --!
     !value 11!value 12! .... !value 1n!
     !-- Another commented row --!
     !value m1!value m2! .... !value mn!

    By default all column values are trimmed. To avoid trimming the values, use the "trim" inlined property:

     | header 1 | header 2 | .... | header n |
     | value 11 | value 12 | .... | value 1n |

    Comments is column values are supported via the "commentSeparator" inlined property:

     | header 1#comment | header 2 | .... | header n |
     | value 11#comment | value 12 | .... | value 1n |
    Comments including the separator are stripped.

    The table allows the retrieval of row values as converted parameters. Use getRowAsParameters(int) and invoke Parameters.valueAs(String, Type) specifying the header and the class type of the parameter.

    The table allows the transformation of its string representation via the "transformer" inlined property (multiple transformers will be applied in chain-mode):

     |header 1|header 2| .... |header n|
     |value 11|value 12| .... |value 1n|
     |value m1|value m2| .... |value mn|
    The transformers need to be registered by name via the TableTransformers.useTransformer(String, TableTransformer). A few transformers are already registered by default in TableTransformers.

    The table allow filtering on meta by row via the "metaByRow" inlined property:

     | Meta:       | header 1 | .... | header n |
     | @name=value | value 11 | .... | value 1n |

    Once created, the table row can be modified, via the withRowValues(int, Map) method, by specifying the map of row values to be changed.

    A table can also be created by providing the entire data content, via the withRows(List) method.

    The parsing code assumes that the number of columns for data rows is the same as in the header, if a row has less fields, the remaining are filled with empty values, if it has more, the fields are ignored.
