Constructor Detail

ConditionalExpression

public ConditionalExpression(java.lang.String booleanExpression,
                             java.util.HashMap<java.lang.String,java.lang.String> variablesMap)

Create a new instance with a boolean expression.

Parameters:

booleanExpression - the boolean expression, which supports placeholder variables

variablesMap - a map of variables whose values can replace the values of placeholder variables, key = variable name, value = variable value

See Also:

EXPRESSION_TYPE_BOOLEAN_EXPRESSION

ConditionalExpression

public ConditionalExpression(java.lang.String regexInput,
                             java.lang.String regex,
                             java.util.HashMap<java.lang.String,java.lang.String> variablesMap)

Create a new instance with a boolean Regex.

Parameters:

regexInput - the input to which the Regex is applied.

regex - the Regex itself, which supports placeholder variables. the placeholder variables are replaced first, before the Regex is evaluated

variablesMap - a map of variables whose values can replace the values of placeholder variables, key = variable name, value = variable value
