All Implemented Interfaces:

Comparable, MethodSummary.Variable, jwutil.io.Textualizable

Enclosing class:

MethodSummary

public static final class MethodSummary.FieldNode
extends MethodSummary.OutsideNode

A FieldNode represents the result of a 'load' instruction. There are outside edge links from the nodes that can be the base object of the load to this node. Two nodes are equal if the fields match and they are from the same instruction.

Method Detail

get

public static MethodSummary.FieldNode get(MethodSummary.Node base,
                                          jq_Field f,
                                          ProgramLocation obj)

unify

public static MethodSummary.FieldNode unify(jq_Field f,
                                            Set s)

Returns a new FieldNode that is the unification of the given set of FieldNodes. In essence, all of the given nodes are replaced by a new, returned node. The given field nodes must be on the given field.

replaceBy

public void replaceBy(Set set,
                      boolean removeSelf)

Description copied from class: MethodSummary.Node

Replace this node by the given set of nodes. All inside and outside edges to and from this node are replaced by sets of edges to and from the nodes in the set. The passed parameter set of this node is also added to every node in the given set.

Overrides:

replaceBy in class MethodSummary.Node

update

public void update(HashMap um)

Description copied from class: MethodSummary.Node

Update all predecessor and successor nodes with the given update map. Also clones the passed parameter set.

Overrides:

update in class MethodSummary.Node

getAccessPathPredecessors

public Set getAccessPathPredecessors()

Return the set of outside edge predecessors of this node.

getField

public jq_Field getField()

getDefiningMethod

public jq_Method getDefiningMethod()

Description copied from class: MethodSummary.Node

Return the method that this node is defined in, null if it doesn't come from a method.

Specified by:

getDefiningMethod in class MethodSummary.Node

getLocations

public Set getLocations()

fieldName

public String fieldName()

copy

public final MethodSummary.Node copy()

Description copied from class: MethodSummary.Node

Return a shallow copy of this node.

Specified by:

copy in class MethodSummary.Node

getDeclaredType

public jq_Reference getDeclaredType()

Description copied from class: MethodSummary.Node

Return the declared type of this node.

Specified by:

getDeclaredType in class MethodSummary.OutsideNode

toString_long

public String toString_long()

Description copied from class: MethodSummary.Node

Return a string representation of the node in long form. Includes inside and outside edges and passed parameters.

Overrides:

toString_long in class MethodSummary.Node

toString_short

public String toString_short()

Description copied from class: MethodSummary.Node

Return a string representation of the node in short form.

Specified by:

toString_short in class MethodSummary.Node

write

public void write(jwutil.io.Textualizer t)
           throws IOException

Specified by:

write in interface jwutil.io.Textualizable

Overrides:

write in class MethodSummary.Node

Throws:

IOException

read

public static MethodSummary.FieldNode read(StringTokenizer st)
