  +--de.hunsicker.jalopy.language.MethodType

All Implemented Interfaces:

Comparable, Type

public class MethodType

extends Object

implements Comparable, Type

Represents a method type to distinguish between ordinary method names and those which adhere to the Java Bean naming conventions.

The default order for comparing is: ordinary Java method names, mutator, accessor/tester. This can be changed via setOrder(java.lang.String).

Field Detail

GETTER

public static final MethodType GETTER

Represents a Java Bean accessor.

SETTER

public static final MethodType SETTER

Represents a Java Bean mutator.

TESTER

public static final MethodType TESTER

Represents a Java Bean accessor/tester.

OTHER

public static final MethodType OTHER

Represents an ordinary Java method.

Method Detail

setOrder

public static void setOrder(String str)

Sets the order to use as the natural order.

Parameters:

str - a string representing the new order. The string must consist of exactly four different, comma delimited strings which represents a method type (e.g. isFoo,getFoo,setFoo,foo)

Throws:

IllegalArgumentException - if the given string is invalid.

getOrder

public static String getOrder()

Returns a string representation of the current sort order. To encode the different method types, the common foo abreviation is used:

      

       isFoo,getFoo,setFoo,foo  or
       foo,getFoo,isFoo,setFoo  or
       ...
      
      

Returns:

a string representation of the current sort order.

compareTo

public int compareTo(Object other)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Specified by:

compareTo in interface Comparable

Parameters:

other - the object to be compared.

Returns:

DOCUMENT ME!

Throws:

ClassCastException - if the specified object's type prevents it from being compared to this object.

toString

public String toString()

Returns a string representation of this method type.

Overrides:

toString in class Object

Returns:

a string representation of this type.

valueOf

public static MethodType valueOf(String name)

Returns the method type of the given method name.

Parameters:

name - a method name.

Returns:

the method type of the given name.

Throws:

IllegalArgumentException - if no valid method name is given.

isBean

public boolean isBean()

Indicates whether this type represents a Java Bean method.

Returns:

true if this method type adheres to the Java Bean naming conventions.
