Method Detail

read

protected Attribute read(ClassReader cr,
                         int off,
                         int len,
                         char[] buf,
                         int codeOff,
                         Label[] labels)

Description copied from class: Attribute

Reads a type attribute. This method must return a new Attribute object, of type type, corresponding to the len bytes starting at the given offset, in the given class reader.

Overrides:

read in class SourceDebugExtensionAttribute

Parameters:

cr - the class that contains the attribute to be read.

off - index of the first byte of the attribute's content in cr.b. The 6 attribute header bytes, containing the type and the length of the attribute, are not taken into account here.

len - the length of the attribute's content.

buf - buffer to be used to call readUTF8, readClass or readConst.

codeOff - index of the first byte of code's attribute content in cr.b, or -1 if the attribute to be read is not a code attribute. The 6 attribute header bytes, containing the type and the length of the attribute, are not taken into account here.

labels - the labels of the method's code, or null if the attribute to be read is not a code attribute.

Returns:

a new Attribute object corresponding to the given bytes.

asmify

public void asmify(java.lang.StringBuffer buf,
                   java.lang.String varName,
                   java.util.Map labelNames)

Description copied from interface: ASMifiable

Prints the ASM code to create an attribute equal to this attribute.

Specified by:

asmify in interface ASMifiable

Parameters:

buf - A buffer used for printing Java code.

varName - name of the variable in a printed code used to store attribute instance.

labelNames - map of label instances to their names.
