Method Detail

parseBufferIntoLines

public static final java.util.Vector parseBufferIntoLines(java.io.InputStream stream)

Parse a stream of bytes into lines delimited by newline characters

Parameters:

stream -

Returns:

A Vector of String's, each of which represents one line. Trailing CR, LF characters are stripped away. Returns null if there was a problem.

tokenize

public static final java.lang.String[] tokenize(java.lang.String str,
                                                java.lang.String delimiter)

Break apart string into tokens delimited by another string.

Parameters:

str - Input string to tokenize

delimiter - Another string which delimits tokens

Returns:

An array of string tokens

tokenize

public static final java.lang.String[] tokenize(java.lang.String str,
                                                java.lang.String delimiter,
                                                int limit)

getLocaleName

public static final java.lang.String getLocaleName(java.lang.String baseName,
                                                   Locale locale)

Create a property/bundle name of the form "baseName_language_country_variant". Note that if any of the components {language, country, variant} is null or empty, that part (and the preceding underscore) will be omitted from the result.

Parameters:

baseName -

locale -

Returns:

handleEscapeChars

public static java.lang.String handleEscapeChars(java.lang.String str)

fullNameToXmlFileName

public static final java.lang.String fullNameToXmlFileName(java.lang.String fullName)

Convert a fully-qualified classname, like "oracle.adfnmc.model.Products", to a filename relative to the predefined resources base directory, like "/res/oracle/adfnmc/model/Products.xml"

Parameters:

fullName - Fully-qualified classname, e.g. "oracle.adfnmc.model.Products"

Returns:

Absolute filename, e.g. "/res/oracle/adfnmc/model/Products.xml"

fullNameToPropertiesFileName

public static final java.lang.String fullNameToPropertiesFileName(java.lang.String fullName)

fullNameToXliffFileName

public static final java.lang.String fullNameToXliffFileName(java.lang.String fullName)

fullNameToPathName

public static final java.lang.String fullNameToPathName(java.lang.String fullName)

getAppConfigDefinedDir

public static java.lang.String getAppConfigDefinedDir(java.lang.String key,
                                                      java.lang.String defaultVal,
                                                      boolean isJarPath)

Utility method for getting application file configurable paths. A slash separator will be appended to the return value, so callers should not insert a slash character between the result of this call and any descendant path strings as they build up a path.

Parameters:

key -

defaultVal -

isJarPath - TODO

Returns:

getAppConfigFile

public static final PropertyBag getAppConfigFile()

Get the properties for this application. These are typically stored in a JAD file and then loaded during app initialization

Returns:

A PropertyBag which can be used to retrieve values by String keys

getAppConfigFileAsMap

public static final Map getAppConfigFileAsMap()

getMetadataBasedir

public static final java.lang.String getMetadataBasedir()

Deprecated. - Now just use getRootPath() + the path of the resource relative to the root of the jar it is packaged in

-Internal- Get the base path for application metadata resources

Returns:

getDefaultResourceLoader

public static final ResourceLoader getDefaultResourceLoader()

getResourceAsStream

public static final java.io.InputStream getResourceAsStream(java.lang.String resName)

Load the requested resource and return it as an InputStream for reading

Parameters:

resName - Name of resource, like "res/Foo.png" or "/res/SRDEMO.sql"

Returns:

An InputStream if resName was found, or null if it was not

isEmpty

public static final boolean isEmpty(java.lang.String s)

Is the provided string empty?

Parameters:

s - string to test
