Method Detail

stripLastWord

public static String stripLastWord(String prefix)

Looks behind, gets stuff after the white space. Basically ripping out the last word.

getPreviousExpression

public static String getPreviousExpression(String backText)

getLastExpression

public static String getLastExpression(String backText)

getInnerExpression

public static String getInnerExpression(String backText)

nestedExpressionIndex

public static int nestedExpressionIndex(char[] chars,
                                        int start,
                                        char type)

stripWhiteSpace

public static String stripWhiteSpace(String prefix)

getCompilableText

public static String getCompilableText(String backText)

Attempt to enhance a consequence backtext such that it should compile in MVEL

Parameters:

backText -

Returns:

a substring of the back text, that should be compilable without syntax errors by the mvel compiler TODO: add tests and more use cases

isGetter

public static boolean isGetter(String methodName,
                               int argCount,
                               String returnedType)

isSetter

public static boolean isSetter(String methodName,
                               int argCount,
                               String returnedType)

isIsGetter

public static boolean isIsGetter(String methodName,
                                 int argCount,
                                 String returnedType)

getPropertyName

public static String getPropertyName(String methodName,
                                     int parameterCount,
                                     String returnType)

Given a data depicting a method (name, # or params/args, returned type key), tries to return a bean property name derived from that method. If a bean property name is not found, the initial method name is returned

Parameters:

methodName -

parameterCount -

returnType -

Returns:

a bean property name

getPropertyName

public static String getPropertyName(String methodName,
                                     char[] signature)

getWritablePropertyName

public static String getWritablePropertyName(String methodName,
                                             int parameterCount,
                                             String returnType)

Given a data depicting a method (name, # or params/args, returned type key), tries to return a writable bean property name derived from that method. If a writable (ie setter) bean property name is not found, the initial method name is returned

Parameters:

methodName -

parameterCount -

returnType -

Returns:

a bean property name

getWritablePropertyName

public static String getWritablePropertyName(String methodName,
                                             char[] signature)

Parameters:

cls - -- class reference

Returns:

Simple name of class

getTextWithoutPrefix
