Constructor Detail

SpelParserConfiguration

public SpelParserConfiguration()

Create a new SpelParserConfiguration instance with default settings.

SpelParserConfiguration

public SpelParserConfiguration(SpelCompilerMode compilerMode,
                               java.lang.ClassLoader compilerClassLoader)

Create a new SpelParserConfiguration instance.

Parameters:

compilerMode - the compiler mode for the parser

compilerClassLoader - the ClassLoader to use as the basis for expression compilation

SpelParserConfiguration

public SpelParserConfiguration(boolean autoGrowNullReferences,
                               boolean autoGrowCollections)

Create a new SpelParserConfiguration instance.

Parameters:

autoGrowNullReferences - if null references should automatically grow

autoGrowCollections - if collections should automatically grow
