| CtMethod | | final public class CtMethod extends CtBehavior (Code) | | An instance of CtMethod represents a method.
See the super class CtBehavior since
a number of useful methods are in CtBehavior.
A number of useful factory methods are in CtNewMethod.

| Constructor Summary | |
| | CtMethod(MethodInfo minfo, CtClass declaring)
| | public | CtMethod(CtClass returnType, String mname, CtClass[] parameters, CtClass declaring)
Creates a public abstract method. | | public | CtMethod(CtMethod src, CtClass declaring, ClassMap map)
Creates a copy of a CtMethod object.
The created method must be
added to a class with CtClass.addMethod().
All occurrences of class names in the created method
are replaced with names specified by
map if map is not null.
For example, suppose that a method at() is as
follows:
public X at(int i) {
return (X)super.elementAt(i);
}
(X is a class name.) If map substitutes
String for X, then the created method is:
public String at(int i) {
return (String)super.elementAt(i);
}
By default, all the occurrences of the names of the class
declaring at() and the superclass are replaced
with the name of the class and the superclass that the
created method is added to.
This is done whichever map is null or not.
To prevent this replacement, call ClassMap.fix().
Note: if the .class notation (for example,
String.class) is included in an expression, the
Javac compiler may produce a helper method.
Since this constructor never
copies this helper method, the programmers have the responsiblity of
copying it. |
| Method Summary | |
| public boolean | equals(Object obj)
Indicates whether obj has the same name and the
same signature as this method. | | public String | getName()
Obtains the name of this method. | | public CtClass | getReturnType()
Obtains the type of the returned value. | | final String | getStringRep()
| | public int | hashCode()
Returns a hash code value for the method. | | public boolean | isEmpty()
Returns true if the method body is empty, that is, {}. | | public static CtMethod | make(String src, CtClass declaring)
Compiles the given source code and creates a method.
This method simply delegates to make() in
CtNewMethod. | | public void | setBody(CtMethod src, ClassMap map)
Copies a method body from another method. | | public void | setName(String newname)
Changes the name of this method. | | public void | setWrappedBody(CtMethod mbody, ConstParameter constParam)
Replace a method body with a new method body wrapping the
given method. |
| CtMethod | | public CtMethod(CtClass returnType, String mname, CtClass[] parameters, CtClass declaring)(Code) | | Creates a public abstract method. The created method must be
added to a class with CtClass.addMethod().
Parameters:
declaring - the class to which the created method is added.
Parameters:
returnType - the type of the returned value
Parameters:
mname - the method name
Parameters:
parameters - a list of the parameter types

| CtMethod | | public CtMethod(CtMethod src, CtClass declaring, ClassMap map) throws CannotCompileException(Code) | | Creates a copy of a CtMethod object.
The created method must be
added to a class with CtClass.addMethod().
All occurrences of class names in the created method
are replaced with names specified by
map if map is not null.
For example, suppose that a method at() is as
follows:
public X at(int i) {
return (X)super.elementAt(i);
}
(X is a class name.) If map substitutes
String for X, then the created method is:
public String at(int i) {
return (String)super.elementAt(i);
}
By default, all the occurrences of the names of the class
declaring at() and the superclass are replaced
with the name of the class and the superclass that the
created method is added to.
This is done whichever map is null or not.
To prevent this replacement, call ClassMap.fix().
Note: if the .class notation (for example,
String.class) is included in an expression, the
Javac compiler may produce a helper method.
Since this constructor never
copies this helper method, the programmers have the responsiblity of
copying it. Otherwise, use Class.forName() in the
expression.
Parameters:
src - the source method.
Parameters:
declaring - the class to which the created method is added.
Parameters:
map - the hashtable associating original class nameswith substituted names.It can be null.

| equals | | public boolean equals(Object obj)(Code) | | Indicates whether obj has the same name and the
same signature as this method.
|
| getName | | public String getName()(Code) | | Obtains the name of this method.
|
| hashCode | | public int hashCode()(Code) | | Returns a hash code value for the method.
If two methods have the same name and signature, then
the hash codes for the two methods are equal.
|
| isEmpty | | public boolean isEmpty()(Code) | | Returns true if the method body is empty, that is, {}.
It also returns true if the method is an abstract method.
|
| make | | public static CtMethod make(String src, CtClass declaring) throws CannotCompileException(Code) | | Compiles the given source code and creates a method.
This method simply delegates to make() in
CtNewMethod. See it for more details.
CtNewMethod has a number of useful factory methods.
Parameters:
src - the source text.
Parameters:
declaring - the class to which the created method is added.
See Also: CtNewMethod.make(StringCtClass) |
| setBody | | public void setBody(CtMethod src, ClassMap map) throws CannotCompileException(Code) | | Copies a method body from another method.
If this method is abstract, the abstract modifier is removed
after the method body is copied.
All occurrences of the class names in the copied method body
are replaced with the names specified by
map if map is not null.
Parameters:
src - the method that the body is copied from.
Parameters:
map - the hashtable associating original class nameswith substituted names.It can be null. |
| setName | | public void setName(String newname)(Code) | | Changes the name of this method.
