Tells whether or not the given string string matches the given regular expression.

An invocation of this method of the form matches(str, regex) yields exactly the same result as the expression

Pattern. matches (regex, str)

Parameters:

pString - the string

pRegex - the regular expression to which this string is to be matched

Returns:

true if, and only if, this string matches the given regular expression

Throws:

java.util.regex.PatternSyntaxException - if the regular expression's syntax is invalid

Replaces the first substring of the given string that matches the given regular expression with the given pReplacement.

An invocation of this method of the form replaceFirst(str, regex, repl) yields exactly the same result as the expression

Pattern.compile(regex). matcher(str). replaceFirst(repl)

Parameters:

pString - the string

pRegex - the regular expression to which this string is to be matched

pReplacement - the replacement text

Returns:

The resulting String

Throws:

java.util.regex.PatternSyntaxException - if the regular expression's syntax is invalid

replaceAll

public java.lang.String replaceAll(java.lang.String pString,
                          java.lang.String pRegex,
                          java.lang.String pReplacement)

Replaces each substring of this string that matches the given regular expression with the given pReplacement.

An invocation of this method of the form replaceAll(str, pRegex, repl<) yields exactly the same result as the expression

Pattern.compile(pRegex). matcher(str). {@link java.util.regex.Matcher#replaceAll replaceAll}(repl)

Parameters:

pString - the string

pRegex - the regular expression to which this string is to be matched

pReplacement - the replacement string

Returns:

The resulting String

Throws:

java.util.regex.PatternSyntaxException - if the regular expression's syntax is invalid

See Also:

Pattern, String.replaceAll(String,String)

split

public java.lang.String[] split(java.lang.String pString,
                       java.lang.String pRegex,
                       int pLimit)

Splits this string around matches of the given regular expression.

The array returned by this method contains each substring of this string that is terminated by another substring that matches the given expression or is terminated by the end of the string. The substrings in the array are in the order in which they occur in this string. If the expression does not match any part of the input then the resulting array has just one element, namely this string.

The pLimit parameter controls the number of times the pattern is applied and therefore affects the length of the resulting array. If the pLimit n is greater than zero then the pattern will be applied at most n - 1 times, the array's length will be no greater than n, and the array's last entry will contain all input beyond the last matched delimiter. If n is non-positive then the pattern will be applied as many times as possible and the array can have any length. If n is zero then the pattern will be applied as many times as possible, the array can have any length, and trailing empty strings will be discarded.

An invocation of this method of the form split(str, regex, n) yields the same result as the expression

Pattern. compile(regex). split(str, n)

Parameters:

pString - the string

pRegex - the delimiting regular expression

pLimit - the result threshold, as described above

Returns:

the array of strings computed by splitting this string around matches of the given regular expression

Throws:

java.util.regex.PatternSyntaxException - if the regular expression's syntax is invalid

See Also:

Pattern, String.split(String,int)

split

public java.lang.String[] split(java.lang.String pString,
                       java.lang.String pRegex)

Splits this string around matches of the given regular expression.

This method works as if by invoking the two-argument split method with the given expression and a limit argument of zero. Trailing empty strings are therefore not included in the resulting array.

Parameters:

pString - the string

pRegex - the delimiting regular expression

Returns:

the array of strings computed by splitting this string around matches of the given regular expression

Throws:

java.util.regex.PatternSyntaxException - if the regular expression's syntax is invalid

See Also:

Pattern, String.split(String)

camelToLisp

public static java.lang.String camelToLisp(java.lang.String pString)

Parameters:

pString - the camel-style input string

Returns:

the string converted to lisp-style naming convention

Throws:

java.lang.IllegalArgumentException - if pString == null

See Also:

lispToCamel(String)

lispToCamel

public static java.lang.String lispToCamel(java.lang.String pString)

Eg. "foo" => "foo", "foo-bar" => "fooBar", "http-request-wrapper" => "httpRequestWrapper" "my-45-caliber" => "my45Caliber" "allreadyCamel" => "allreadyCamel"

Parameters:

lispToCamel

public static java.lang.String lispToCamel(java.lang.String pString,

Converts the input string from Lisp-style naming convention (hyphen delimitted, all lower case) to camel-style (Java in-fix) naming convention. Other characters in the string are left untouched.

To create a string starting with a lower case letter (like Java variable names, etc), specify the pFirstUpperCase paramter to be false. Eg. "foo" => "foo", "foo-bar" => "fooBar", "allreadyCamel" => "allreadyCamel"

To create a string starting with an upper case letter (like Java class name, etc), specify the pFirstUpperCase paramter to be true. Eg. "http-request-wrapper" => "HttpRequestWrapper" "my-45-caliber" => "My45Caliber"

Parameters:

pString - the lisp-style input string

pFirstUpperCase - true if the first char should be upper case

Returns:
