Constructor Detail

IlrRuntimeException

protected IlrRuntimeException(Throwable target,
                              Member member)

Constructs an IlrRuntimeException with a target exception thrown by the JVM and a Java reflection member (method or field) which has caused the exception.

Parameters:

target - The target exception.

member - The target reflection member.

IlrRuntimeException

protected IlrRuntimeException(Throwable target)

Constructs an exception using a target exception object thrown by the JVM.

Parameters:

target - The target exception.

Method Detail

getMessage

public String getMessage()

Overrides:

getMessage in class Throwable

getTargetMember

public Member getTargetMember()

Returns the target member (a field, a method or a constructor of some class in the application) which caused the exception.

Returns:

a member (field, method or constructor), or null if the exception is not related to a specific class member.

getTargetException

public Throwable getTargetException()

Returns the target exception reported by the Java virtual machine.

Returns:

a throwable object. This exception is never null.

printRuleStackTrace

public void printRuleStackTrace()

Prints the rule stack trace to System.err. A rule stack trace does not include the stack trace of the original Java exception.

printRuleStackTrace

public void printRuleStackTrace(PrintWriter s)

Prints the rule stack trace to a PrintWriter. A rule stack trace does not include the stack trace of the original Java exception.

Parameters:

s - The PrintWriter to write the rule stack trace.

printHeader

public void printHeader(PrintWriter s)

Prints the header of the rule stack trace. The header is composed of the exception class name.

Parameters:

s - The PrintWriter to write the rule stack trace.

printRuleStackTrace

public void printRuleStackTrace(PrintStream s)

Prints the rule stack trace to a PrintStream. A rule stack trace does not include the stack trace of the original Java exception.

printStackTrace

public void printStackTrace()

Prints a stack trace using the target member and the target exception. A stack trace is composed of a rule stack trace and the original Java exception's stack trace.

Overrides:

printStackTrace in class Throwable

printStackTrace

public void printStackTrace(PrintWriter s)

Prints a stack trace using the target member and the target exception. A stack trace is composed of a rule stack trace and the original Java exception's stack trace.

Overrides:

printStackTrace in class Throwable

Parameters:

s - A print writer to which the stack trace will be printed.

printStackTrace

public void printStackTrace(PrintStream s)

Prints a stack trace using the target member and the target exception. A stack trace is composed of a rule stack trace and the original Java exception's stack trace.

Overrides:

printStackTrace in class Throwable

Parameters:

s - A print stream to which the stack trace will be printed.
