Field Details

scriptSource

protected String scriptSource

The source of the script.

shouldBeCompiled

protected volatile boolean shouldBeCompiled

Flag to signal if the script should be compiled

compiledScriptSourceDigest

protected volatile String compiledScriptSourceDigest

Digest of the processed script source used to produce the current CompiledExecutableScript.compiledScript. A null value indicates no compiled artifact is present.

Constructor Details

SourceExecutableScript

public SourceExecutableScript(String language,
 String source)

Method Details

evaluate

public Object evaluate(ScriptEngine engine,
 VariableScope variableScope,
 Bindings bindings)

Overrides:

evaluate in class CompiledExecutableScript

compileScript

protected void compileScript(ScriptEngine engine,
 String processedScript)

compile

public CompiledScript compile(ScriptEngine scriptEngine,
 String language,
 String src)

evaluateScript

protected Object evaluateScript(ScriptEngine engine,
 String processedScript,
 Bindings bindings)
                         throws ScriptException

Throws:

ScriptException

getScriptSource

public String getScriptSource()

setScriptSource

public void setScriptSource(String scriptSource)

Sets the script source code. And invalidates any cached compilation result.

Parameters:

scriptSource - the new script source code

invalidateCompiledScript

protected void invalidateCompiledScript()

Invalidates all cached compilation state for this script instance.

This method clears the currently cached compiled artifact and its associated source digest, and marks the script as eligible for compilation on the next evaluation. The method is synchronized to guarantee that cache reset is applied atomically with respect to concurrent evaluation and source updates.

isShouldBeCompiled

public boolean isShouldBeCompiled()
