Method Detail

getTheInstance

public static GlobalFunctions getTheInstance()

Returns:

theInstance

generateRegEx

public static RegEx generateRegEx(java.lang.String string)

Parameters:

string - input String

Returns:

ArrayList of RegExParts

searchVariableDefinition

public AbstractVariableDefinition searchVariableDefinition(RouterSoftware rs,
                                                           java.lang.String identifier)
                                                    throws ParserException

gets the VariableDefinition of the searched Identifier.

Parameters:

rs - The RouterSoftware to use.

identifier - identifier

Returns:

the VariableDefiniton for an Identifier

Throws:

ParserException - ParserException if VariableDefinition is not found

convertToGeneralIdentifier

public java.lang.String convertToGeneralIdentifier(java.lang.String identifier)

createRESP

private static RegExStringPart createRESP(java.lang.String string)

yet another totally senseless function for PMD to be quiet. Suppresses "Avoid instantiating new objects inside loops" warning.

Parameters:

string - string

Returns:

RegExStringPart

getInstance

private static GlobalFunctions getInstance()

Returns:

the instance

setInstance

private static void setInstance(GlobalFunctions instance)

Parameters:

instance - the instance to set
