Constructor Detail

AbstractAsmClassScanningBeanDefinitionReader

public AbstractAsmClassScanningBeanDefinitionReader(org.springframework.beans.factory.support.BeanDefinitionRegistry beanFactory)

Parameters:

beanFactory -

Method Detail

addTypeFilter

public void addTypeFilter(TypeFilter tf)

isComponentOrFactoryClass

protected boolean isComponentOrFactoryClass(org.objectweb.asm.ClassReader classReader)

Parameters:

classReader - ASM ClassReader for the class

Returns:

true if this class is a component or component factory class and thus of interest to us

searchClass

protected int searchClass(java.io.InputStream stream)
                   throws java.io.IOException

Search the given stream for class information. ASM library is used to parse the stream and extract the classname. Using the stream allows consistent behavior when reading classes across network, from jars or just folders without creating a classloader implementation.

Specified by:

searchClass in class AbstractClassScanningBeanDefinitionReader

Parameters:

stream -

Returns:

Throws:

java.io.IOException
