Method Detail

where

public CtBehavior where()
Returns the constructor or method containing the expression.


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.


indexOfBytecode

public int indexOfBytecode()
Returns the index of the bytecode corresponding to the expression. It is the index into the byte array containing the Java bytecode that implements the method.


getLineNumber

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

Returns:
-1 if this information is not available.

getFileName

public java.lang.String getFileName()
Returns the source file containing the expression.

Returns:
null if this information is not available.
