Class DebugDiagnostic

java.lang.Object
  extended by oracle.jbo.common.DebugDiagnostic


public final class DebugDiagnostic
extends java.lang.Object

Provides tracing and logging methods for use during application development.

This class cannot be directly instantiated; it is instantiated in DiagonsticFactory#createDiagnostic().

These methods can be invoked even in critical code sections, because all methods in this class will be compiled out of the production release of the product.

Since:
Jdeveloper 3.0

Method Detail

print

public static void print(java.lang.String message,
                         int level)
Prints a trace message to the diagnostic device.
Parameters:
message - the text to be printed.
level - the message's nesting level.

print

public static void print(java.lang.String message)
Prints a trace message.
Parameters:
message - the text to be printed.

println

public static void println(java.lang.String message,
                           int level)
Prints a trace message line to the diagnostic device.
Parameters:
message - the text to be printed.
level - the message's nesting level.

println

public static void println(java.lang.String message)
Prints a trace message line to the diagnostic device.
Parameters:
message - the text to be printed.

ASSERT

public static void ASSERT(boolean test,
                          java.lang.String message,
                          java.lang.Object[] param)
Conditionally prints a warning message.

The message is constructed from a format string and an array of parameters. An exception is raised if enabled by setStopOnAssert().

Parameters:
test - the result of the test being asserted.
message - the message's format string.
param - the array of message parameters.
Throws:
JboAssert - if test is true.

ASSERT

public static void ASSERT(boolean test,
                          java.lang.String message)
Conditionally prints a warning message and raises an exception.

An exception is raised if enabled by setStopOnAssert().

Parameters:
test - the result of the test being asserted.
message - the message.
Throws:
JboAssert - if test is true.

ASSERT

public static void ASSERT(boolean test)
Conditionally raises an exception.

An exception is raised if enabled by setStopOnAssert().

Parameters:
test - the result of the test being asserted.
Throws:
JboAssert - if test is true.

NULL

public static void NULL(java.lang.String s)
Does nothing: this method allows fragments of code to be embedded that will be compiled away for release-mode builds.
Parameters:
s - not used.

setStopOnAssert

public static void setStopOnAssert(boolean b)
Enables ASSERT() methods to throw exceptions.
Parameters:
b - if true, subsequent invocations of ASSERT() methods will throw exceptions.

printStackTrace

public static void printStackTrace()
Prints a stack trace for the current environment.

printStackTrace

public static void printStackTrace(java.lang.Throwable ex)
Prints a stack trace for an exception.
Parameters:
ex - the exception to be traced.
