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 CtClass getType()
                throws NotFoundException

Returns the CtClass object representing the type name on the right hand side of the instanceof operator.

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 instanceof 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
