                           JIPipeExpressionVariablesMap expressionVariables)

Generates an annotation value

Parameters:

strings - existing annotations for the data

expressionVariables - expression parameters

Returns:

the annotation that matches the query or null if none matches

test

public boolean test(Path string)

Returns true if the query matches the string

Specified by:

test in interface Predicate<Path>

Parameters:

string - the string

Returns:

if the query matches

test

public boolean test(Path string,
                    JIPipeExpressionVariablesMap expressionVariables)

Returns true if the query matches the string

Parameters:

string - the string

Returns:

if the query matches

testAnyOf

public boolean testAnyOf(Collection<Path> strings,
                         JIPipeExpressionVariablesMap expressionVariables)

Returns true of one of the strings matches the query.

Parameters:

strings - the strings

expressionVariables - expression variables

Returns:

if one string matches
