Method Detail

isBlankOrNull

public static boolean isBlankOrNull(java.lang.String string)

Checks if the string is a blank or null. This interface signature is needed because the content server's components are loaded via reflection and without it you get this error: java.lang.NoSuchMethodError: oracle.stellent.wcm.common.utils.WCMCommonUtils.isBlankOrNull(Ljava/lang/String;)Z

Parameters:

string - string to be tested

Returns:

true if the string is null or blank

isBlankOrNull

public static boolean isBlankOrNull(java.lang.Object value)

Checks if a object is null, and if the object is a string then that it is not blank or null

Parameters:

value - object to check for null

Returns:

true, if null or blank

isTrue

public static boolean isTrue(java.lang.String string)

Checks if a string represents a true value

Parameters:

string -

Returns:

false unless string is "1" or starts with either "T" or "t"

getCsvFromCollection

public static java.lang.String getCsvFromCollection(java.util.Collection collection)

Constructs string from a collection

Parameters:

collection - source collection of values

Returns:

Comma-separated string as a result of values concatenation

getListFromCsv

public static java.util.List<java.lang.String> getListFromCsv(java.lang.String value)

Parses comma delimited string to List of String instances

Parameters:

value - Comma delimited string to parse

Returns:

List of Strings extractecd from comma-separated line

isValidElementName

public static boolean isValidElementName(java.lang.String string)

Checks if the string is a valid name for elements, which must follow the JSTL Expression Language Spec. The name must be a valid java variable name and must not be one of the EL reserved words http://java.sun.com/docs/books/tutorial/java/nutsandbolts/variables.html http://java.sun.com/j2ee/1.4/docs/tutorial/doc/JSPIntro7.html

Parameters:

string -

Returns:

true if the string is a valid element name

isValidVariableName

public static boolean isValidVariableName(java.lang.String string)

isJSTLELKeyword

public static boolean isJSTLELKeyword(java.lang.String string)

isJavaKeyword

public static boolean isJavaKeyword(java.lang.String string)

getSegment

public static java.lang.String getSegment(java.lang.String str,
                                          java.lang.String separator,
                                          int segment)

Returns the segment, null if not found, first segment is segment 0

Parameters:

str - Source string

separator - Parsing separator

segment - String segment number

Returns:

Specified segment of the string extracted

evaluateRegexWithCallback

public static java.lang.String evaluateRegexWithCallback(java.lang.String text,
                                                         java.lang.String regEx,
                                                         WCMCommonUtils.RegexAppendCallback callback)

Analyze a string and invoke a callback when a match is found.

Parameters:

text - the text to analyze

regEx - the regular rexpression to match

callback - the callback to invoke when a match is found

Returns:

the modified string

capitalize

public static java.lang.String capitalize(java.lang.String name)

This is the inverse method to the decapitalize() in the Introspector class (@see Introspector.decapitalize(String). This allows as to handle names which starts with a single lowercase char followed by a upper case char in the name. We convert the starting lower case char to upper case so that the Introspector class will correctly map our names to the property names in the bean class. Currently affected names: dSecurityName, dDocAccount, xClbraUserList, xClbraAliasList

Parameters:

name - the property name

Returns:

capitalized name (only first 2 chars are capitalized if required).

nonNull

public static java.lang.String nonNull(java.lang.String original)

This makes sure that the string not null, if it is null then an empty string is returned

Parameters:

original - the original string

Returns:

the original string after trimming or an empty string if it is null.
