Method Detail

where

public CtBehavior where()
Returns the method or constructor containing the instanceof expression represented by this object.

Overrides:
where in class Expr

getLineNumber

public int getLineNumber()
Returns the line number of the source line containing the instanceof 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 instanceof expression.

Overrides:
getFileName in class Expr
Returns:
null if this information is not available.

getType

public CompileTimeClass getType()
                         throws NotFoundException
Returns the CtClass object representing the type name on the right hand side of the instanceof operator.

Throws:
NotFoundException

mayThrow

public CompileTimeClass[] 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 instanceof operator with the bytecode derived from the given source text.

$0 is available but the value is null.

Parameters:
statement - a Java statement.
Throws:
CannotCompileException
