Method Summary

Modifier and Type	Method	Description
String	getFileName()	Returns the source file containing the type-cast expression.

Method Details

where

public CtBehavior where()

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

Overrides:

where in class Expr

getLineNumber

public int getLineNumber()

Returns the line number of the source line containing the type-cast expression.

Overrides:

getLineNumber in class Expr

Returns:

-1 if this information is not available.

getFileName

public String getFileName()

Returns the source file containing the type-cast expression.

Overrides:

getFileName in class Expr

Returns:

null if this information is not available.

getType

public CtClass getType()
                throws NotFoundException

Returns the CtClass object representing the type specified by the cast.

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

public void replace(String statement)
             throws CannotCompileException

Replaces the explicit cast operator with the bytecode derived from the given source text.

$0 is available but the value is null.

Specified by:

replace in class Expr

Parameters:

statement - a Java statement except try-catch.

Throws:

CannotCompileException
