specialText

public static java.lang.String specialText(Token t)

已过时。 use getSpecialText(Token t)

getSpecialText

public static org.apache.commons.lang.text.StrBuilder getSpecialText(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.

参数:

t - the Token

返回:

StrBuilder with the special tokens.

tokenLiteral

public static java.lang.String tokenLiteral(Token t)

complete node literal

参数:

t -

返回:

A node literal.

interpolate

public static java.lang.String interpolate(java.lang.String argStr,
                                           Context vars)
                                    throws MethodInvocationException

已过时。 this method isn't called by any class

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.

参数:

argStr -

vars -

返回:

Interpoliation result.

抛出:

MethodInvocationException
