Method Detail

balancedCapture

public static int balancedCapture(char[] chars,
                                  int start,
                                  char type,
                                  String templateFileName)

This is an important aspect of the core parser tools. This method is used throughout the core parser and sub-lexical parsers to capture a balanced capture between opening and terminating tokens such as: ( [ { ' "

For example: ((foo + bar + (bar - foo)) * 20;

If a balanced capture is performed from position 2, we get "(foo + bar + (bar - foo))" back.
If a balanced capture is performed from position 15, we get "(bar - foo)" back.
Etc.

Parameters:

chars - -

start - -

type - -

templateFileName - -

Returns:

-

balancedCapture

public static int balancedCapture(char[] chars,
                                  int start,
                                  int end,
                                  char type,
                                  String templateFileName)

captureStringLiteral

public static int captureStringLiteral(char type,
                                       char[] expr,
                                       int cursor,
                                       int end,
                                       String templateFileName)

createCompileException

public static org.everit.templating.util.CompileException createCompileException(String templateName,
                                                                                 String message,

                                                                                 int cursor,

Instantiates a new CompileException based on the parameters.

Parameters:

templateName - The name of the template or null if no template name is available. If defined, the template name will be concatenated with the message.

message - The message of the exception.

expr - The expression that caused the exception

cursor - The cursor within the expression character array.

cause - The cause of the exception.

Returns:

The instantiated CompileException.
