Method Detail

interpolate

public static String interpolate(String argStr, Context vars)
Utility method to interpolate context variables into string literals. So that the following will work: #set $name = "candy" $image.getURI("${name}.jpg") And the string literal argument will be transformed into "candy.jpg" before the method is executed.

specialText

public static String specialText(Token t)
Collect all the s that are carried along with a token. Special tokens do not participate in parsing but can still trigger certain lexical actions. In some cases you may want to retrieve these special tokens, this is simply a way to extract them.

tokenLiteral

public static String tokenLiteral(Token t)
complete node literal
