getProgram

public java.lang.String getProgram(java.lang.String... statements)

getSubProgram

public java.util.List<java.lang.String> getSubProgram(ExprDef exprDef)

Description copied from class: ExprScriptEngineFactory

Returns a subprogram for the specified ExprDef. The subprogram may be included in an engine specific script that aggregates individual scripts.

The subprogram should define a fuction that is invokable within the context of a containing script.

Similar to ScriptEngineFactory.getProgram(String...).

Specified by:

getSubProgram in class ExprScriptEngineFactory

Returns:

a List of statements that can be included as a function in an aggregate script.

getSubPrograms

public java.util.List<CodeSourceImpl.MethodSource> getSubPrograms(ExprCodeSource codeSource)

Description copied from class: ExprScriptEngineFactory

An approximate inverse to #getSubprogram(ExprDef).

Specified by:

getSubPrograms in class ExprScriptEngineFactory

Returns:

a List of MethodSources representing the ExprDef subprograms that are present in the CodeSource.

getParseCount

public long getParseCount()

Description copied from class: ExprScriptEngineFactory

The number of script parses that were performed by the engine.

Specified by:

getParseCount in class ExprScriptEngineFactory

getExecuteCount

public long getExecuteCount()

Description copied from class: ExprScriptEngineFactory

The number of script executions that were performed by the engine.

Specified by:

getExecuteCount in class ExprScriptEngineFactory

getCacheHitCount

public long getCacheHitCount()

Description copied from class: ExprScriptEngineFactory

The number of hit on the engine's script cache. The engine holds a cache of parsed script instances. A hit count indicates that the evaluator was able to frequently reuse scripts that were parsed for an earlier expression execution.

Specified by:

getCacheHitCount in class ExprScriptEngineFactory

getCacheMissCount

public long getCacheMissCount()

Description copied from class: ExprScriptEngineFactory

The number of misses on the engine's script cache.

Specified by:

getCacheMissCount in class ExprScriptEngineFactory

getNamePrefix

public java.lang.String getNamePrefix()

Description copied from class: ExprScriptEngineFactory

Returns a prefix that may be used to identify scripts genereated by this engine.

Specified by:

getNamePrefix in class ExprScriptEngineFactory

getNamePostfix

public java.lang.String getNamePostfix()

Description copied from class: ExprScriptEngineFactory

Returns a postfix that may be used to identify scripts generated by this engine.

Specified by:

getNamePostfix in class ExprScriptEngineFactory
