All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.Map, VariableResolver

public class DefaultVariableResolver
extends java.util.HashMap
implements VariableResolver

The DefaultVariableResolver is a HashMap based default implementation of the VariableResolver interface. It may be used by plugins to implement the interface for the request and is also used by the WebConsoleUtil.getVariableResolver(javax.servlet.ServletRequest) as the variable resolver if none has yet been assigned to the request.

Constructor Detail

DefaultVariableResolver

public DefaultVariableResolver()

Creates a new variable resolver with default capacity.

DefaultVariableResolver

public DefaultVariableResolver(int initialCapacity,
                               float loadFactor)

DefaultVariableResolver

public DefaultVariableResolver(java.util.Map source)

Creates a new variable resolver copying the variables from the given map.

Parameters:

source - the map whose variables are to be placed in this resolver.

Method Detail

resolve

public java.lang.String resolve(java.lang.String variable)

Returns the string representation of the value stored under the variable name in this map. If no value is stored under the variable name, null is returned.

Specified by:

resolve in interface VariableResolver

Parameters:

variable - The name of the variable whose value is to be returned.

Returns:

The variable value or null if there is no entry with the given name in this map.
