Method Detail

where

public CtBehavior where()

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

Overrides:

where in class Expr

getLineNumber

public int getLineNumber()

Returns the line number of the source line containing the new expression.

Overrides:

getLineNumber in class Expr

Returns:

-1 if this information is not available.

getFileName

public String getFileName()

Returns the source file containing the new expression.

Overrides:

getFileName in class Expr

Returns:

null if this information is not available.

getClassName

public String getClassName()

Returns the class name of the created object.

getSignature

public String getSignature()

Get the signature of the constructor The signature is represented by a character string called method descriptor, which is defined in the JVM specification.

Returns:

the signature

getConstructor

public CtConstructor getConstructor()
                             throws NotFoundException

Returns the constructor called for creating the object.

Throws:

NotFoundException

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

replace

Parameters:

statement - a Java statement except try-catch.

Throws:
