Method Detail

computeExpressionObjects

protected Map<String,Object> computeExpressionObjects()

getExpressionObjects

public Map<String,Object> getExpressionObjects()

Description copied from interface: IProcessingContext

Returns the map of expression objects that should be made available to every expression evaluation operation (whenever variable evaluation is available). In OGNL and SpringEL expressions, these will be available as #object1, #object2, etc.

This method cannot return null, and must return a modifiable Map object (which will, in fact, be modified).

Specified by:

getExpressionObjects in interface IProcessingContext

Returns:

the map of objects

getContext

public IContext getContext()

Description copied from interface: IProcessingContext

Returns the current context specified for template processing.

Specified by:

getContext in interface IProcessingContext

Returns:

the current context

getExpressionEvaluationRoot

public Object getExpressionEvaluationRoot()

Description copied from interface: IProcessingContext

Returns the current evaluation root. This is the object on which expressions (normal expressions, like those specified in the standard dialect with ${...}) are executed.

Specified by:

getExpressionEvaluationRoot in interface IProcessingContext

Returns:

the expression evaluation root

getExpressionSelectionEvaluationRoot

public Object getExpressionSelectionEvaluationRoot()

Description copied from interface: IProcessingContext

Returns the current selection evaluation root. This is the object on which selection expressions (like those specified in the standard dialect with *{...}) are executed.

Specified by:

getExpressionSelectionEvaluationRoot in interface IProcessingContext

Returns:

the selection evaluation root

hasSelectionTarget

public boolean hasSelectionTarget()

Description copied from interface: IProcessingContext

Returns whether there currently is a selection going on (e.g. th:object in standard dialect).

Specified by:

hasSelectionTarget in interface IProcessingContext

Returns:

true if there is a selection currently established, false if not

getSelectionTarget

public Object getSelectionTarget()

Description copied from interface: IProcessingContext

Returns the selection target object, and raises an exception if there isn't any.

Meant for internal use.

Specified by:

getSelectionTarget in interface IProcessingContext

Returns:

the selection target object

hasLocalVariables

public boolean hasLocalVariables()

Description copied from interface: IProcessingContext

Returns whether local variables have currently been specified or not. (e.g. th:with in standard dialect).

Specified by:

hasLocalVariables in interface IProcessingContext

Returns:

true if there are local variables, false if not

hasLocalVariable

public boolean hasLocalVariable(String variableName)

Description copied from interface: IProcessingContext

Returns whether a specific local variable is defined or not.

Specified by:

hasLocalVariable in interface IProcessingContext

Parameters:

variableName - the name of the local variable to be checked.

Returns:

true if the variable is currently defined, false if not.

getLocalVariable

public Object getLocalVariable(String variableName)

Description copied from interface: IProcessingContext

Returns the value of a local variable.

Specified by:

getLocalVariable in interface IProcessingContext

Parameters:

variableName - the name of the local variable to be returned.

Returns:

the value of the variable, or null if the variable does not exist (or has null value).

getLocalVariables

public Map<String,Object> getLocalVariables()

Description copied from interface: IProcessingContext

Returns the map of local variables.

Specified by:

getLocalVariables in interface IProcessingContext

Returns:

the local variables

mergeNewLocalVariables

protected Map<String,Object> mergeNewLocalVariables(Map<String,Object> newVariables)
