Method Detail

checkParams

public static void checkParams(Class<?> helperClazz,
                               HelperDefinition definition,
                               int paramSize)

Parameters:

helperClazz -

definition -

paramSize -

Throws:

MustacheException - If the helper tag params

checkType

public static void checkType(Class<?> helperClazz,
                             HelperDefinition definition,
                             MustacheTagType... allowedTypes)

Parameters:

helperClazz -

definition -

allowedTypes -

Throws:

MustacheException - If the helper tag type does not match any one of the specified types

checkHash

public static void checkHash(Class<?> helperClazz,
                             HelperDefinition definition,
                             int hashSize)

Parameters:

helperClazz -

definition -

hashSize -

Throws:

MustacheException - If the helper tag params

splitHelperName

@Internal
public static Iterator<String> splitHelperName(String name,
                                                         Segment segment)

Extracts parts from an input string. This implementation is quite naive and should be possibly rewritten. Note that we can't use a simple splitter because of string literals may contain whitespace chars.

Parameters:

name -

segment -

Returns:

the parts of the helper name

Throws:

MustacheException - If a compilation problem occures

getFirstDeterminingEqualsCharPosition

public static int getFirstDeterminingEqualsCharPosition(String part)

Parameters:

part -

Returns:

the index of an equals char outside of any string literal, -1 if no such char is found
