Method Detail

isEqualDataPath

public static boolean isEqualDataPath(AbstractDataPath path1,
                                      AbstractDataPath path2)

Compares two AbstractDataPath object each other. The result is true if and only if they represents the same sequence of segments.

Parameters:

path1 - - a first path

path2 - - a second path

Returns:

true if the given paths represents the same sequence of segments, false otherwise.

Throws:

NullPointerException - in case one from the specified paths is null

isEqualDataPath

public static boolean isEqualDataPath(AbstractFormDataSourceInfo info1,
                                      AbstractFormDataSourceInfo info2)

Compares two AbstractFormDataSource#getDataPath(ScriptVariant) object each other.

Parameters:

info1 - the first property info

info2 - the second property info

Returns:

true if the given paths represents the same sequence of segments, false otherwise.

Throws:

NullPointerException - in case one from the specified paths is null

startsWith

public static boolean startsWith(AbstractDataPath verifiable,
                                 AbstractDataPath prefix)

Tests if the verifiable data path starts with the specified prefix data path.

Parameters:

verifiable - the verifiable

prefix - the prefix

Returns:

true if the verifiable data path starts with a prefix data path; false otherwise.

isElementDataPath

public static boolean isElementDataPath(AbstractDataPath path)

Checks the data path is a data path of form element

Parameters:

path - the data path

Returns:

return true if is data path of form element.

hasIndex

public static boolean hasIndex(AbstractDataPath path)

The method checks a AbstractDataPath contains indexes data

Parameters:

path - the checking path

Returns:

true if path contains any indexes data; false the otherways

getIndexForSegment

public static Integer[] getIndexForSegment(AbstractDataPath path)

Gets indexes data for segments

Parameters:

path - the path for gets indexes data

Returns:

returns the array with values of indexes for the corresponding segments. Length of returning array equals size of path segments. If segments not contains index then array value equals null

setIndexForSegment

public static void setIndexForSegment(AbstractDataPath path,
                                      Integer[] indexes)

Sets indexes data for segments of the data path

Important: the indexes will be set to current data path, do not forget using the copy data path.

Parameters:

path - the data path to which it will be set indexes.

indexes - the setting indexes

getDataPathForCurrentScriptVariant

public static AbstractDataPath getDataPathForCurrentScriptVariant(AbstractDataPath sourceDataPath,
                                                                  Form form,
                                                                  ScriptVariant scriptVariant,
                                                                  IDataSourceInfoAssociationService associationService)

getDataPathForAutoTable

public static AbstractDataPath getDataPathForAutoTable(DataItem item)

Returns TableHolder's parent path for auto-table which has no data path itself (e.g. GanttChart's embedded table in 8.3.21+)

Parameters:

item - the auto-table candidate, cannot be null

Returns:

path of the parent of TableHolder, can be null
