Interface JexlScript
A script is some valid JEXL syntax to be executed with a given set of JexlContext variables.
A script is a group of statements, separated by semicolons.
The statements can be blocks (curly braces containing code),
 Control statements such as if and while
 as well as expressions and assignment statements.
Do not create classes that implement this interface; delegate or compose instead.

Method Details- 
callableCreates a Callable from this script.This allows to submit it to an executor pool and provides support for asynchronous calls. The interpreter will handle interruption/cancellation gracefully if needed. - Parameters:
- context- the context
- Returns:
- the callable

- 2.1

- context- the context
- args- the script arguments
- Returns:
- the callable
- Since:
- 2.1
 
- 
curryCurries this script, returning a script with bound arguments.If this script does not declare parameters or if all of them are already bound, no error is generated and this script is returned. - Parameters:
- args- the arguments to bind
- Returns:
- the curried script or this script if no binding can occur
 
- 
executeExecutes the script with the variables contained in the suppliedJexlContext.- Parameters:
- context- A JexlContext containing variables.
- Returns:
- The result of this script, usually the result of the last statement.
 
- 
executeExecutes the script with the variables contained in the suppliedJexlContextand a set of arguments corresponding to the parameters used during parsing.- Parameters:
- context- A JexlContext containing variables.
- args- the arguments
- Returns:
- The result of this script, usually the result of the last statement.

- 2.1

getLocalVariablesGets this script local variables.- Returns:
- the local variables or null
- Since:
- 2.1
 
- 
getParametersString[] getParameters()Gets this script parameters.- Returns:
- the parameters or null
- Since:
- 2.1
 
- 
getParsedTextRecreates the source text of this expression from the internal syntactic tree.- Returns:
- the source text
 
- 
getParsedTextRecreates the source text of this expression from the internal syntactic tree.- Parameters:
- indent- the number of spaces for indentation, 0 meaning no indentation
- Returns:
- the source text
 
- 
getPragmasGets this script pragmas.- Returns:
- the (non null, may be empty) pragmas map
 
- 
getSourceTextReturns the source text of this expression.- Returns:
- the source text
 
- 
getUnboundParametersGets this script unbound parameters.Parameters that haven't been bound by a previous call to curry(). - Returns:
- the parameters or null
- Since:
- 3.2
 
- 
getVariablesSet<List<String>> getVariables()Gets this script variables.Note that since variables can be in an ant-ish form (ie foo.bar.quux), each variable is returned as a list of strings where each entry is a fragment of the variable ({"foo", "bar", "quux"} in the example. - Returns:
- the variables or null
- Since:
- 2.1
