Method Detail

getTargets

java.util.List<org.objectweb.asm.tree.AbstractInsnNode> getTargets(java.util.Map<java.lang.String,IInjectionTarget> injectionTargets,
                                                                   org.objectweb.asm.tree.MethodNode method,
                                                                   CTarget target,
                                                                   CSlice slice)

Get all matching target instructions.

Parameters:

injectionTargets - All existing injection targets

method - The method to search in

target - The CTarget annotation

slice - The CSlice annotation

Returns:

The matching instructions

getShift

default CTarget.Shift getShift(CTarget target)

Get the shift for this target.
By default, it is defined in the CTarget annotation.

Parameters:

target - The CTarget annotation

Returns:

The shift

getSlice

default java.util.List<org.objectweb.asm.tree.AbstractInsnNode> getSlice(java.util.Map<java.lang.String,IInjectionTarget> injectionTargets,
                                                                         org.objectweb.asm.tree.MethodNode method,
                                                                         CSlice slice)

Get all instructions in the given slice.

Parameters:

injectionTargets - All existing injection targets

method - The method to search in

slice - The CSlice annotation

Returns:

The instructions in the slice

Throws:

java.lang.IllegalArgumentException - If the slice is invalid
