Method Detail

parse

public IStandardExpression parse(String expression)

Parses an expression, returning the matching expression type.

Parameters:

expression -

Returns:

Matching expression type.

parseFragmentExpression

public FragmentExpression parseFragmentExpression(String expression)

Parses an expression under the assumption it is a fragment expression. This method will wrap fragment expressions written in Thymeleaf 2 syntax as a backwards compatibility measure for those migrating their web apps to Thymeleaf 3. (This is because Thymeleaf 3 currently does the same, but expect this method to go away when Thymeleaf starts enforcing the new fragment expression syntax itself.)

Parameters:

expression -

Returns:

A fragment expression.

process

public Object process(String expression)

Parse and executes an expression, returning whatever the type of the expression result is.

Parameters:

expression -

Returns:

The result of the expression being executed.

processAsString

public String processAsString(String expression)

Parse and execute an expression, returning the result as a string. Useful for expressions that expect a simple result.

Parameters:

expression -

Returns:

The expression as a string.

getContext

public final IExpressionContext getContext()
