Method Detail
-
getInternalForm
public java.lang.String getInternalForm(java.lang.String className, boolean descriptor)
Converts the given class name to its internal form.- Parameters:
className
- the name to convertdescriptor
- true if the name is to be used for a descriptor section -- the difference seems to be that for descriptors, non-primitives are prefixed with 'L' and ended with ';'
-
getExternalForm
public java.lang.String getExternalForm(java.lang.String internalName, boolean humanReadable)
Given the internal name of the class, return the 'normal' java name.- Parameters:
internalName
- the internal name being usedhumanReadable
- if the returned name should be in human-readable form, rather than a form suitable for aClass.forName(java.lang.String)
call -- the difference lies in the handling of arrays
-
getDescriptor
public java.lang.String getDescriptor(java.lang.String returnType, java.lang.String[] paramTypes)

-
getDescriptorParamNames
public java.lang.String[] getDescriptorParamNames(java.lang.String descriptor)
Return the parameter types, in internal form, for the given method descriptor string.
-
getComponentName
public java.lang.String getComponentName(java.lang.String name)
