de.ipcon.db.grooql.FilterGroovyScript

public class FilterGroovyScript
extends GroovyScript

Sandboxed GroovyScript execution environment for GrooQL filter expressions.

Enforces strict AST restrictions (no method or closure declarations, no arbitrary imports and restricted statement/expression token allowlists).

Method Summary

Modifier and Type	Method and Description
java.lang.Object	evalNT(java.lang.String s, java.lang.Object nullValue, int lineOffset, java.lang.String errorTip) Evaluates a string as a script with a specified null value and line offset and returns the result as Object.
org.codehaus.groovy.control.CompilerConfiguration	getCompilerConfiguration(java.util.List<ScriptImport> imports, java.lang.String baseClassName) Adds custom compiling options to the given CompilerConfiguration.
java.lang.Object	runAsObjectNT(java.lang.Object nullValue, int lineOffset, java.lang.String errorTip) This method is called *NT ("no throw") but actually does throw a GroovyScriptException should the script throw an exception while running.

Method Detail

getCompilerConfiguration

public org.codehaus.groovy.control.CompilerConfiguration getCompilerConfiguration(java.util.List<ScriptImport> imports,
                                                                                  java.lang.String baseClassName)

Description copied from class: GroovyScript

Adds custom compiling options to the given CompilerConfiguration. We need to cache these instances as the performance penalty of using a fresh one is suprisingly high.

runAsObjectNT

public java.lang.Object runAsObjectNT(java.lang.Object nullValue,
                                      int lineOffset,
                                      java.lang.String errorTip)

Description copied from class: GroovyScript

This method is called *NT ("no throw") but actually does throw a GroovyScriptException should the script throw an exception while running.

Overrides:

runAsObjectNT in class GroovyScript

Parameters:

nullValue - The value to return if the script returns null.

lineOffset - An integer line offset to use for error reporting.

errorTip - A string to use as an error message tip if compilation fails.

Returns:

The result of the script execution as Object or "nullValue" if the script returned null.

evalNT

public java.lang.Object evalNT(java.lang.String s,
                               java.lang.Object nullValue,
                               int lineOffset,
                               java.lang.String errorTip)

Description copied from class: AbstractScript

Evaluates a string as a script with a specified null value and line offset and returns the result as Object.

Overrides:

evalNT in class GroovyScript

Parameters:

s - The source of the script to evaluate.

nullValue - The value to return if the evaluation returns null.

lineOffset - An integer line offset to use for error reporting.

errorTip - A string to use as an error message tip if evaluation fails.

Returns:

The result of the script evaluation as Object or "nullValue" if the evaluation returned null.
