Constructor Detail

ELContextWrapper

public ELContextWrapper(ELContext target,
                        FunctionMapper fnMapper)

Construct a new ELContextWrapper.

Parameters:

target - The target ELContext to wrap

fnMapper - The function mapper to use

Method Detail

getELResolver

public ELResolver getELResolver()

Description copied from class: jakarta.el.ELContext

Returns the ELResolver used to resolve properties and method invocations during expression evaluation.

Specified by:

getELResolver in class ELContext

Returns:

the ELResolver for this context

getFunctionMapper

public FunctionMapper getFunctionMapper()

Description copied from class: jakarta.el.ELContext

Returns the FunctionMapper used to resolve EL function names to Java methods during expression evaluation.

Specified by:

getFunctionMapper in class ELContext

Returns:

the FunctionMapper for this context

getVariableMapper

public VariableMapper getVariableMapper()

Description copied from class: jakarta.el.ELContext

Returns the VariableMapper used to resolve EL variable names to ValueExpression instances during expression evaluation.

Specified by:

getVariableMapper in class ELContext

Returns:

the VariableMapper for this context

getContext

public java.lang.Object getContext(java.lang.Class<?> key)

Description copied from class: jakarta.el.ELContext

Obtain the context object for the given key.

Overrides:

getContext in class ELContext

Parameters:

key - The key of the required context object

Returns:

The value of the context object associated with the given key

getLocale

public java.util.Locale getLocale()

Description copied from class: jakarta.el.ELContext

Returns the locale associated with this EL context. The locale is used for type conversion operations such as parsing numbers and dates during expression evaluation.

Overrides:

getLocale in class ELContext

Returns:

the locale for this context, or null if not set

isPropertyResolved

public boolean isPropertyResolved()

Description copied from class: jakarta.el.ELContext

Returns whether a property has been resolved during the current evaluation step. ELResolver implementations call ELContext.setPropertyResolved(boolean) to indicate resolution, and the expression evaluator checks this flag to determine if resolution was successful.

Overrides:

isPropertyResolved in class ELContext

Returns:

true if a property has been resolved, false otherwise

putContext

public void putContext(java.lang.Class<?> key,
                       java.lang.Object contextObject)
                throws java.lang.NullPointerException

Description copied from class: jakarta.el.ELContext

Add an object to this EL context under the given key.

Overrides:

putContext in class ELContext

Parameters:

key - The key under which to store the object

contextObject - The object to add

Throws:

java.lang.NullPointerException - If the supplied key or context is null

setLocale

public void setLocale(java.util.Locale locale)

Description copied from class: jakarta.el.ELContext

Sets the locale for this EL context. The locale is used for type conversion operations such as parsing numbers and dates during expression evaluation.

Overrides:

setLocale in class ELContext

Parameters:

locale - the locale to use for this context

setPropertyResolved

public void setPropertyResolved(boolean resolved)

Description copied from class: jakarta.el.ELContext

Sets the internal flag indicating whether a property has been resolved during the current evaluation step. This method is used by ELResolver implementations to signal that they have handled the current base/property combination.

Overrides:

setPropertyResolved in class ELContext

Parameters:

resolved - true if a property has been resolved, false otherwise
