Method Detail

getResourceStream

protected final InputStream getResourceStream()
                                       throws ResourceNotFoundException

Overrides:

getResourceStream in class ClassPathResource

Throws:

ResourceNotFoundException

equals

public boolean equals(Object o)

Two ClassPathStylesheetResource are equal if both of them are instances of ClassPathStylesheetResource and the equals method of ClassPathResource is true.

Overrides:

equals in class ClassPathResource

Returns:

true if the two instances are equal.

hashCode

public int hashCode()

Simple hascode implementation

Overrides:

hashCode in class ClassPathResource

Returns:

a hashcode, comprised from the hashcodes of the classloader and from the file name of the resource.

bufferResource

protected StaticResource.LimitedBuffer bufferResource()
                                               throws IOException,
                                                      ResourceNotFoundException

Description copied from class: StaticResource

Reads the resource into an LimitedBuffer and returns it. If the size of the resource is larger than StaticResource.LimitedBuffer.MAX_SIZE_TO_BUFFER, then the returned Buffer is empty and does not contain the Resource's content (and the isValid() flag is false).

Overrides:

bufferResource in class StaticResource

Returns:

buffered resource as LimitedBuffer, that may be invalid, if the size of the resource is beyond MAX_SIZE_TO_BUFFER. It is null, if the Resource returned an invalid stream.

Throws:

IOException

ResourceNotFoundException
