public JavaUtils()

Method Detail

isJavaKeyword

public static boolean isJavaKeyword(String keyword)

Checks if the input string is a valid java keyword.

Returns:

Returns boolean.

Check if the word has any uppercase letters

Parameters:

word -

Returns:

makeNonJavaKeyword

public static String makeNonJavaKeyword(String keyword)

Turns a java keyword string into a non-Java keyword string. (Right now this simply means appending an underscore.)

converts an xml name to a java identifier

Parameters:

name -

Returns:

java identifier

isTrue

public static boolean isTrue(String value)

Tests the String 'value': return 'false' if its 'false', '0', or 'no' - else 'true'

Follow in 'C' tradition of boolean values: false is specific (0), everything else is true;

isTrueExplicitly

public static boolean isTrueExplicitly(String value)

Tests the String 'value': return 'true' if its 'true', '1', or 'yes' - else 'false'

isTrueExplicitly

public static boolean isTrueExplicitly(Object value,
                                       boolean defaultVal)

Tests the Object 'value': if its null, return default. if its a Boolean, return booleanValue() if its an Integer, return 'false' if its '0' else 'true' if its a String, return isTrueExplicitly((String)value). All other types return 'true'

isTrueExplicitly

public static boolean isTrueExplicitly(Object value)

isTrue

public static boolean isTrue(Object value,
                             boolean defaultVal)

Tests the Object 'value': if its null, return default. if its a Boolean, return booleanValue() if its an Integer, return 'false' if its '0' else 'true' if its a String, return 'false' if its 'false', 'no', or '0' - else 'true' All other types return 'true'

isTrue

public static boolean isTrue(Object value)

isFalse

public static boolean isFalse(String value)

Tests the String 'value': return 'true' if its 'false', '0', or 'no' - else 'false'

Follow in 'C' tradition of boolean values: false is specific (0), everything else is true;

isFalseExplicitly

public static boolean isFalseExplicitly(String value)

Tests the String 'value': return 'true' if its null, 'false', '0', or 'no' - else 'false'

isFalseExplicitly

public static boolean isFalseExplicitly(Object value,
                                        boolean defaultVal)

Tests the Object 'value': if its null, return default. if its a Boolean, return !booleanValue() if its an Integer, return 'true' if its '0' else 'false' if its a String, return isFalseExplicitly((String)value). All other types return 'false'

isFalseExplicitly

public static boolean isFalseExplicitly(Object value)

isFalse

public static boolean isFalse(Object value,
                              boolean defaultVal)

isJavaId

public static boolean isJavaId(String id)

split

public static String[] split(String str,
                             char separatorChar)

Splits the provided text into an array, separator specified. This is an alternative to using StringTokenizer.

The separator is not included in the returned String array. Adjacent separators are treated as one separator.

A null input String returns null.

 StringUtils.split(null, *)         = null
 StringUtils.split("", *)           = []
 StringUtils.split("a.b.c", '.')    = ["a", "b", "c"]
 StringUtils.split("a..b.c", '.')   = ["a", "b", "c"]
 StringUtils.split("a:b:c", '.')    = ["a:b:c"]
 StringUtils.split("a\tb\nc", null) = ["a", "b", "c"]
 StringUtils.split("a b c", ' ')    = ["a", "b", "c"]
 

Parameters:

str - the String to parse, may be null

separatorChar - the character used as the delimiter, null splits on whitespace

Returns:

an array of parsed Strings, null if null String input

getWrapperClass

public static Class getWrapperClass(Class primitive)

getWrapperClass

public static Class getWrapperClass(String primitive)

indexOfIgnoreCase

public static int indexOfIgnoreCase(String string,
                                    String search)

Scans the parameter string for the parameter search ignoring case when comparing characters.

Parameters:

string -

search - If test is empty -1 is always returned.

Returns:

-1 if the string was not found or the index of the first matching character

replace

public static final String replace(String name,
                                   String oldT,
                                   String newT)

replace: Like String.replace except that the old new items are strings.

Parameters:

name - string

oldT - old text to replace

newT - new text to use

Returns:

replacement string

callStackToString

public static String callStackToString()

Get a string containing the stack of the current location. Note This utility is useful in debug scenarios to dump out the call stack.

Returns:

String

stackToString

public static String stackToString(Throwable e)

Get a string containing the stack of the specified exception

Parameters:

e -

Returns:

getObjectIdentity

public static String getObjectIdentity(Object obj)

Mimics the default Object.toString() produces a string of the form: obj.getClass().getName() + "@" + object's hashCode. This method can be used to print the debug message when you want just the short name or if using the toString will cause full expansion of underlying data structures. The returned value can also be used as an identity key.

Returns:

obj.getClass().getName() + "@" + Integer.toHexString(System.identityHashCode(obj));
