Methods Summary
public java.lang.Object	getContext(java.lang.Class key) Returns the context object associated with the given key. The ELContext maintains a collection of context objects relevant to the evaluation of an expression. These context objects are used by ELResolvers. This method is used to retrieve the context with the given key from the collection. By convention, the object returned will be of the type specified by the key. However, this is not required and the key is used strictly as a unique identifier. param key The unique identifier that was used to associate the context object with this ELContext. return The context object associated with the given key, or null if no such context was found. throws NullPointerException if key is null. if(key == null) { throw new NullPointerException(); } return map.get(key);
public abstract javax.el.ELResolver	getELResolver() Retrieves the ELResolver associated with this context. The ELContext maintains a reference to the ELResolver that will be consulted to resolve variables and properties during an expression evaluation. This method retrieves the reference to the resolver. Once an ELContext is constructed, the reference to the ELResolver associated with the context cannot be changed. return The resolver to be consulted for variable and property resolution during expression evaluation.
public abstract javax.el.FunctionMapper	getFunctionMapper() Retrieves the FunctionMapper associated with this ELContext. return The function mapper to be consulted for the resolution of EL functions.
public java.util.Locale	getLocale() Get the Locale stored by a previous invocation to {@link #setLocale}. If this method returns non null, this Locale must be used for all localization needs in the implementation. The Locale must not be cached to allow for applications that change Locale dynamically. return The Locale in which this instance is operating. Used primarily for message localization. return this.locale;
public abstract javax.el.VariableMapper	getVariableMapper() Retrieves the VariableMapper associated with this ELContext. return The variable mapper to be consulted for the resolution of EL variables.
public boolean	isPropertyResolved() Returns whether an {@link ELResolver} has successfully resolved a given (base, property) pair. The {@link CompositeELResolver} checks this property to determine whether it should consider or skip other component resolvers. see CompositeELResolver return true if the property has been resolved, or false if not. return resolved;
public void	putContext(java.lang.Class key, java.lang.Object contextObject) Associates a context object with this ELContext. The ELContext maintains a collection of context objects relevant to the evaluation of an expression. These context objects are used by ELResolvers. This method is used to add a context object to that collection. By convention, the contextObject will be of the type specified by the key. However, this is not required and the key is used strictly as a unique identifier. param key The key used by an @{link ELResolver} to identify this context object. param contextObject The context object to add to the collection. throws NullPointerException if key is null or contextObject is null. if((key == null) || (contextObject == null)) { throw new NullPointerException(); } map.put(key, contextObject);
public void	setLocale(java.util.Locale locale) Set the Locale for this instance. This method may be called by the party creating the instance, such as JavaServer Faces or JSP, to enable the EL implementation to provide localized messages to the user. If no Locale is set, the implementation must use the locale returned by Locale.getDefault( ). this.locale = locale;
public void	setPropertyResolved(boolean resolved) Called to indicate that a ELResolver has successfully resolved a given (base, property) pair. The {@link CompositeELResolver} checks this property to determine whether it should consider or skip other component resolvers. see CompositeELResolver param resolved true if the property has been resolved, or false if not. this.resolved = resolved;
