Method Detail

convertToNameValueList

public static java.util.List<java.lang.String> convertToNameValueList(java.util.Map map)

Converts a map in a list of name/value pairs.

Parameters:

map - The map.

Returns:

A list of name/value pairs (name=value).

convertToNameValueList

public static java.util.List<java.lang.String> convertToNameValueList(java.util.Map map,
                                                                      boolean urlEncode)

Converts a map in a list of name/value pairs.

Parameters:

map - The map.

urlEncode - if true, encode the values as URLs.

Returns:

A list of name/value pairs (name=value).

loadBinary

public static byte[] loadBinary(java.lang.String classpathResource)

Loads a binary file from the classpath.

Parameters:

classpathResource - The resource path.

Returns:

The content of the classpath resource.

loadBinary

public static byte[] loadBinary(org.springframework.core.io.Resource classpathResource)

Loads a binary file from the classpath.

Parameters:

classpathResource - The resource path.

Returns:

The content of the classpath resource.

unsafeLoadBinary

protected static byte[] unsafeLoadBinary(java.io.InputStream stream)
                                  throws java.io.IOException

Loads a binary file from a stream.

Parameters:

stream - The stream from where to load. It is open, and it won't be closed by this method.

Returns:

The content of the classpath resource.

Throws:

java.io.IOException - In case of error.

loadString

public static java.lang.String loadString(java.lang.String classpathResource)

Loads a text file from the classpath. NB: UTF-8 header are removed!

Parameters:

classpathResource - The resource path.

Returns:

The content of the classpath resource.

loadString

public static java.lang.String loadString(org.springframework.core.io.Resource classpathResource)

Loads a text file from the classpath. NB: UTF-8 header are removed!

Parameters:

classpathResource - The resource path.

Returns:

The content of the classpath resource.

unsafeLoadString

protected static java.lang.String unsafeLoadString(java.io.InputStream stream)
                                            throws java.io.IOException

Loads a text file from a stream.

Parameters:

stream - The stream from where to load. It is open, and it won't be closed by this method.

Returns:

The content of the classpath resource.

Throws:

java.io.IOException - In case of error.

stripUTF8preamble

public static java.lang.String stripUTF8preamble(java.lang.String s)
                                          throws java.io.UnsupportedEncodingException

Strips the UTF8 preamble, if present. NB: the conversion to byte array, and a following strip won't work. The reason is that: new String(UTF8_PREAMBLE).getBytes() != UTF8_PREAMBLE; Here an explanation.

Parameters:

s - The string to strip.

Returns:

The string without the UTF8 preamble.

Throws:

java.io.UnsupportedEncodingException - If the UTF-8 encoding is not supported.

stripUTF8preamble

public static byte[] stripUTF8preamble(byte[] b)

Strips the UTF8 preamble, if present.

Parameters:

b - The array of bytes (characters).

Returns:

The stripped array.

hasUTF8preamble

public static boolean hasUTF8preamble(byte[] b)

Checks if the array starts with the UTF-8 preamble.

Parameters:

b - The array to inspect.

Returns:

true if the array starts with the UTF-8 preamble.

hasUTF8preamble

public static boolean hasUTF8preamble(java.lang.String s)

Checks if the string starts with the UTF-8 preamble.

Parameters:

s - The string to inspect.

Returns:

true if the string starts with the UTF-8 preamble.

uncamelize

public static java.lang.String[] uncamelize(java.lang.String camelString)

Return an array containing all the substrings of camelString, according to this rule: divide camelString into tokens with every token starting from a capital letter to another. Some examples:

1. 'MyCamelString' gives: {my,camel,string}
2. 'myFantasticCamelString' gives: {my,fantastic,camel,string}
3. 'MYCAMELSTRING' gives: {m,y,c,a,m,e,l,s,t,r,i,n,g}

Parameters:

camelString - The string to uncamelize.

Returns:

The string uncamelized.
