Method Summary

Modifier and Type	Method	Description
String	getClassName()	Returns the class name of the target object, which the method is called on.
String	getFileName()	Returns the source file containing the method call.
int	getLineNumber()	Returns the line number of the source line containing the method call.
CtMethod	getMethod()	Returns the called method.
String	getMethodName()	Returns the name of the called method.
String	getSignature()	Returns the method signature (the parameter types and the return type).
boolean	isSuper()	Returns true if the called method is of a superclass of the current class.
CtClass[]	mayThrow()	Returns the list of exceptions that the expression may throw.
void	replace(String statement)	Replaces the method call with the bytecode derived from the given source text.
CtBehavior	where()	Returns the method or constructor containing the method-call expression represented by this object.

Method Details

where

public CtBehavior where()

Returns the method or constructor containing the method-call expression represented by this object.

Overrides:

where in class Expr

getLineNumber

public int getLineNumber()

Returns the line number of the source line containing the method call.

Overrides:

getLineNumber in class Expr

Returns:

-1 if this information is not available.

getFileName

public String getFileName()

Returns the source file containing the method call.

Overrides:

getFileName in class Expr

Returns:

null if this information is not available.

getClassName

public String getClassName()

Returns the class name of the target object, which the method is called on.

getMethodName

public String getMethodName()

Returns the name of the called method.

getMethod

public CtMethod getMethod()
                   throws NotFoundException

Returns the called method.

Throws:

NotFoundException

getSignature

public String getSignature()

Returns the method signature (the parameter types and the return type). The method signature is represented by a character string called method descriptor, which is defined in the JVM specification.

Since:

3.1

See Also:

• CtBehavior.getSignature()
• Descriptor

mayThrow

public CtClass[] mayThrow()

Returns the list of exceptions that the expression may throw. This list includes both the exceptions that the try-catch statements including the expression can catch and the exceptions that the throws declaration allows the method to throw.

Overrides:

mayThrow in class Expr

isSuper

public boolean isSuper()

Returns true if the called method is of a superclass of the current class.

replace

public void replace(String statement)
             throws CannotCompileException

Replaces the method call with the bytecode derived from the given source text.

$0 is available even if the called method is static.

Specified by:

replace in class Expr

Parameters:

statement - a Java statement except try-catch.

Throws:

CannotCompileException
