Method Detail

getInternalForm

public String getInternalForm(String className,
                              boolean descriptor)

Converts the given class name to its internal form.

Parameters:

className - the name to convert

descriptor - 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 String getExternalForm(String internalName,
                              boolean humanReadable)

Given the internal name of the class, return the 'normal' java name.

Parameters:

internalName - the internal name being used

humanReadable - if the returned name should be in human-readable form, rather than a form suitable for a Class.forName(java.lang.String) call -- the difference lies in the handling of arrays

getDescriptor

public String getDescriptor(String returnType,
                            String[] paramTypes)

Construct a method descriptor from the given return and parameter types, which will be converted to internal form.

getDescriptorReturnName

public String getDescriptorReturnName(String descriptor)

Return the return type, in internal form, for the given method descriptor string.

getDescriptorParamNames

public String[] getDescriptorParamNames(String descriptor)

Return the parameter types, in internal form, for the given method descriptor string.

getComponentName

public String getComponentName(String name)

Return the component type name for the given array type, or null if the given string does not represent an array type name. The name given should be in proper Class.forName(java.lang.String) form.

clear

public void clear()

Clear the cache.
