Field Detail

pattern

public static final Pattern pattern

Stores the regular expression that will remove all [] segments.

Constructor Detail

ParameterName

public ParameterName(String name)

Constructs a ParameterName for a given name from the HttpServletRequest. As it is constructed, detects whether or not the name contains indexing or mapping components, and if it does, also creates and stores the stripped name.

Parameters:

name - a name that may or may not contain indexing or mapping

Method Detail

isIndexed

public boolean isIndexed()

Returns true if the name has indexing or mapping components, otherwise false.

getName

public String getName()

Always returns the parameter name as passed in to the constructor. If it contained indexing or mapping components (e.g. [3] or (foo)) they will be present in the String returned.

Returns:

String the name as supplied in the request

getStrippedName

public String getStrippedName()

Returns the name with all indexing and mapping components stripped. E.g. if the name in the request was 'foo[1].bar', this method will return 'foo.bar'.

Returns:

String the name minus indexing and mapping

equals

public boolean equals(Object obj)

Checks for equality as efficiently as possible. First checks for JVM equality to see if we can short circuit, and then checks for equality of the name attribute for a real test.

Overrides:

equals in class Object

toString

public String toString()

Uses the original name as the string representation of the class. This is probably the most useful thing to see in log messages, which is the only place toString will be used.

Overrides:

toString in class Object
