ArgChecker

• java.lang.Object

Fields Summary
private static final boolean	sChecksEnabled
private static final com.sun.enterprise.admin.util.AssertImpl	sImpl

Constructors Summary
private ArgChecker() // need to do this in a static block to guarantee the // setWantStackTrace() call sImpl = new AssertImpl("ArgChecker Failure", AssertImpl.sIllegalArgument); sImpl.setWantStackTrace(false); Assert.assertit(false, "You can't call the ArgChecker constructor!");

Methods Summary
public static void	check(java.lang.String checkMe, int minimumLength, java.lang.String name) Check the String with a custom StringValidator param checkMe a String to check param minimumLength The minimum acceptable length of the String to allow param name The name of the String throws IllegalArgumentException if checkMe is null or zero-length check(checkMe, name, new StringValidator(minimumLength));
public static final void	check(boolean b, java.lang.Object msg) If expression is false, take appropriate action to note the failure. If expression is true, do nothing. param b boolean derived from callers expression. param msg message to be added to IllegalArgumentException upon failure throws IllegalArgumentException if b is false if ( sChecksEnabled ) { sImpl.assertIt(b, msg); }
public static final void	check(long value, long min, long max, java.lang.Object userMsg) Checks that the specified value is in a specified range. A convenience method which calls checkRange() see #checkRange param value the value to be range-checked param min minimum value. value must be >= min param max maximum value. value must be <= max param userMsg additional user message (optional) to be included throws IllegalArgumentException if the specified value is not in the specified range. checkRange(value, min, max, userMsg);
public static void	check(java.lang.Object object, java.lang.String name, com.sun.enterprise.admin.util.Validator validator) Checks that the object is valid generically by using a Validation object. Convenience method. Calls checkValid(). see checkValid(Object, String, IValidator) param object the value to be validated param name name of the object to be validated param validator validation object to validate the object throws IllegalArgumentException if validator says that object is NOT valid checkValid(object, name, validator);
public static void	check(java.lang.Object object, java.lang.String name) Check that the object is valid. Convenience method. Calls checkValid(). see checkValid(Object, String) param object the value to be validated param name name of the object to be validated throws IllegalArgumentException if validator says that object is NOT valid checkValid( object, name);
public static void	check(java.lang.String checkMe, java.lang.String name) Check the String with the standard StringValidator param checkMe a String to check param name The name of the String throws IllegalArgumentException if checkMe is null or zero-length check(checkMe, name, StringValidator.getInstance());
public static final void	checkRange(long value, long min, long max, java.lang.Object userMsg) Checks that the specified value is in a specified range. The test done is ( value >= min && value <= max ) If the test fails, then a descriptive string is generated which lists the value together with the min and max and user-specified message. param value the value to be range-checked param min minimum value. value must be >= min param max maximum value. value must be <= max param userMsg additional user message (optional) to be included throws IllegalArgumentException if the specified value is not in the specified range. if ( sChecksEnabled ) { sImpl.assertRange(value, min, max, userMsg); }
public static void	checkValid(java.lang.Object object, java.lang.String name, com.sun.enterprise.admin.util.Validator validator) Checks that the object is valid generically by using a Validation object. If the validation fails, then the check fails as with other checks. param object the value to be validated param name name of the object to be validated param validator validation object to validate the object throws IllegalArgumentException if validator says that object is NOT valid if ( sChecksEnabled ) { sImpl.assertValid(object, name, validator); }
public static void	checkValid(java.lang.Object object, java.lang.String name) Check that the object is valid. Calls check( object, name, validator ) where validator is either the non-null validator or the object itself, if the object implements IValidator. param object the value to be validated param name name of the object to be validated throws IllegalArgumentException if validator says that object is NOT valid final Validator validator = (object instanceof Validator ) ? (Validator)object : BaseValidator.getInstance(); check( object, name, validator );
