Method Detail

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 java.lang.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(java.lang.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.
Throws:
CannotCompileException
