Method Detail

shouldProcessAnnotations

protected boolean shouldProcessAnnotations()

shouldProcessCode

protected boolean shouldProcessCode()

getScope

protected IMetadataScope getScope()

Specified by:

getScope in class MetadataReader

getParser

public MetadataParser getParser()

Specified by:

readAttributeCore

protected SourceAttribute readAttributeCore(java.lang.String name,
                                            Buffer buffer,
                                            int originalOffset,
                                            int length)

Reads a SourceAttribute from the specified buffer.

Overrides:

readAttributeCore in class MetadataReader

Parameters:

name - The name of the attribute to decode.

buffer - A buffer containing the attribute blob.

originalOffset - The offset of position 0 in the buffer relative to the start of the original class file. This is needed during lazy inflation of CodeAttribute (and possibly others). In the case of CodeAttribute, it is helpful to know exactly where each method's body begins so we can load it on demand at some point in the future.

length - The length of the attribute. Implementations should not rely on buffer.size().
