JvmAssumeCfaEdge

public JvmAssumeCfaEdge(CodeAttribute methodCode,
 int offset,
 boolean isSatisfied)

Create a disconnected JVM CFA assume branch edge.

Parameters:

methodCode - the code attribute of the method the edge belongs to

offset - the offset of the instruction represented by the edge

isSatisfied - an assumption on the branch result

JvmAssumeCfaEdge

public JvmAssumeCfaEdge(JvmCfaNode source,
 JvmCfaNode target,
 CodeAttribute methodCode,
 int offset,
 boolean isSatisfied)

Create a JVM CFA assume branch edge. Also sets it as the entering and leaving edge of the source and target nodes.

Parameters:

source - the source node of the edge

target - the target node of the edge

methodCode - the code attribute of the method the edge belongs to

offset - the offset of the instruction represented by the edge

isSatisfied - an assumption on hte branch result

Method Details

isSatisfied

public boolean isSatisfied()

Returns the assumption on the branch statement result made on this edge.
