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 StackMapTableAttribute
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(StringBuffer buf,
                   String varName,
                   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.

trace

public void trace(StringBuffer buf,
                  Map labelNames)
Description copied from interface: Traceable
Build a human readable representation of the attribute.

Specified by:
trace in interface Traceable
Parameters:
buf - A buffer used for printing Java code.
labelNames - map of label instances to their names.

appendLabel

protected void appendLabel(StringBuffer buf,
                           Map labelNames,
                           Label l)
