Method Detail

generate

public String generate(ExpressionVariables expressionVariables)

Attempts to run the expression. If this fails, the expression itself is returned.

Parameters:

expressionVariables - expression parameters

Returns:

expression result or the expression itself

queryFirst

public String queryFirst(Collection<String> strings,
                         ExpressionVariables expressionVariables)

Queries a string out of the list

Parameters:

strings - existing annotations for the data

expressionVariables - expression parameters

Returns:

the annotation that matches the query or null if none matches

queryAll

public List<String> queryAll(Collection<String> strings,
                             ExpressionVariables 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(String string)

Returns true if the query matches the string

Specified by:

test in interface Predicate<String>

Parameters:

string - the string

Returns:

if the query matches

test

public boolean test(String string,
                    ExpressionVariables expressionVariables)

Returns true if the query matches the string

Parameters:

string - the string

Returns:

if the query matches

testAnyOf

public boolean testAnyOf(Collection<String> strings)

Returns true of one of the strings matches the query.

Parameters:

strings - the strings
