Class CompiledExpressionFactory

java.lang.Object

jakarta.el.ExpressionFactory

io.micronaut.el.CompiledExpressionFactory

public class CompiledExpressionFactory
extends jakarta.el.ExpressionFactory

The ExpressionFactory returning the expressions compiled at compilation time.

The factory does not parse expressions at runtime. An expression that was not compiled, and that is not a literal-expression, cannot be created.

Constructor Details

CompiledExpressionFactory

public CompiledExpressionFactory()

Creates a factory loading the generated expression sources with the SoftServiceLoader.

The sources are loaded with the context class loader of the thread, which is the loader ExpressionFactory.newInstance() locates this factory with, so that the expressions generated into a class loader that is a child of the one holding this class — a deployment, a plugin, an isolated test — are found. The loader of this class is used when the thread has none.

CompiledExpressionFactory

public CompiledExpressionFactory(ClassLoader classLoader)

Creates a factory loading the generated expression sources from the given class loader.

Parameters:

classLoader - The class loader holding the generated sources and the optional parser

CompiledExpressionFactory

public CompiledExpressionFactory(List<ELExpressionSource> sources)

Parameters:

sources - The expression sources

CompiledExpressionFactory

public CompiledExpressionFactory(List<ELExpressionSource> sources,
 @Nullable ELExpressionParser parser)

Parameters:

sources - The expression sources

parser - The parser creating the expressions that were not compiled, can be null
